Finally - Rain causes Lake Lanier to rise (a teeny-tiny bit)
For the first time since this this blog was started nearly two months ago, the level of Lake Lanier went up due to the rain yesterday.
Granted, it only went up by 0.01 feet (about 1/10 of an inch), and it’s already dropping today, but it was certainly nice to see.
December 16th, 2007 at 10:47 am
After a good soaking rain, like last night, it will take a few days for the run-off of watershed to flow into Lake Lanier. 2 inches of rain can rise the level by 6 to 10 inches. That is if ACE does not increase the release amount from Buford Dam to refill Lake Seminole at Florida border.
December 16th, 2007 at 12:33 pm
I took the pots and pans out of my shower, flushed my commode for the first time this month, and during halftime of the Falcons game I plan on washing my car!
Seriously, releases from Buford Dam by the Corps should be reduced this week since the river will be flowing like a mofo.
December 16th, 2007 at 2:01 pm
Jay Randal - “2 inches of rain can rise the level by 6 to 10 inches.”
Not gonna happen with this rain. Regardless of ACE.
I think you are overlooking the seriously depleted soil moisture and very thirsty plants. They will absorb and utilize it first. The soil will retain it (some of the area soils can easily hold 20% water) and the plants will transpirate the water into the air. If you want 6+ inches out on the first rain in a long time you will need to pave over all of the land in Lanier’s catchment area.
Wait … maybe that is the plan…
December 16th, 2007 at 3:06 pm
notanumber > soil in the north Georgia Mountains got prepped for runoff, by a smaller storm a week before this one, but yes some runoff would tend to sink into the dry banks of Lake Lanier. When the watershed has saturated soil, then more runoff into the lake.
December 16th, 2007 at 3:25 pm
Note: The small 6 acre lake next to my property in Stone Mountain has risen dramatically today, but series of small lakes in my area feed into each other.
Will be interesting to see what the level might be in Lanier in about 3 days.
December 16th, 2007 at 5:25 pm
It’s actually been several months since the depth at Lanier went up. You have to harken back to early summer.
December 16th, 2007 at 5:47 pm
I wasn’t sure of the exact date — I don’t have data going back far enough. Do you know exactly when it was?
December 16th, 2007 at 6:00 pm
rkolter - “Will be interesting to see what the level might be in Lanier in about 3 days.”
Yes it will!
Water level is now 1051.00. To reach your minimum prediction Lanier’s water level will need to 1051.50 on Wednesday.
I hope Wednesday proves you correct.
December 16th, 2007 at 6:23 pm
notanumber - where’d you pull that quote from? Or a minimum prediction of 1051.50 from?
Mickey- I’ll look it up Monday for you.
December 16th, 2007 at 9:04 pm
This last storm will give a good indication of what Lake Lanier’s watershed drains into the reservoir from approx. 2 inches of rain. Plus how many days of benefit from the level rise of lake. So watch the ACE outflows from Buford Dam for the next few days versus the intake amount from Georgia mountains. I am hoping for minimum 6 inches of rise between Wednesday and Friday. If my prediction fails, then at least we all get an idea what amount of rain is needed to eventually refill Lake Lanier.
December 16th, 2007 at 9:48 pm
Well, today looks like it’ll be nearly dead even. Tomorrow will be a better test, since they take bigger releases on the weekdays. Yesterday’s inflow was give or take 515 million gallons.
December 16th, 2007 at 11:32 pm
rkolter - “notanumber - where’d you pull that quote from? Or a minimum prediction of 1051.50 from?”
Here is the url for Lanier’s water level - http://waterdata.usgs.gov/ga/nwis/uv?cb_00062=on&format=html&period=3&site_no=02334400
The minimum prediction was as a result of adding Jay Randal’s minimum amount of Lanier’s water level rise, 6″ (or .5 ft) to the level that the USGS measured at 5:30pm today. As I write this the reported level is 1050.98′
(It is not going your way Jay, but you keep stretching out the day of your predicted 6″-10″ rise (from 3 days to now 5 days!) so someday you might be correct. Just keep moving the day on out.)
December 16th, 2007 at 11:33 pm
Back up to 1051.00!
December 17th, 2007 at 6:40 am
notanumber > the full flow runoff into Lanier can take a few days from its watershed. If basically the Lake level rises only a couple inches by Friday, then a 2 inch rainstorm has no benefit to recharge the reservoir. Some areas of Georgia received 3 inches of rain, from this last storm, but I have not seen any confirmed amounts for locations above Lake Lanier. I will not be changing my prediction for beyond Friday > whatever runoff from the storm should all flow into the lake by then.
December 17th, 2007 at 6:42 am
A true test of water rise for Lanier would require the outflow to be shut off for a few days, but ACE would never do it.
December 17th, 2007 at 6:49 am
Correction to last post: Actually I mean only releasing the exact amount of intake into the lake before the storm versus allowing the extra flow from the rain to accumulate.
December 17th, 2007 at 8:18 am
notanumber - Sorry, it looked like you were quoting me. You were talking to me, but quoting Jay. My bad.
Mickey - 7/28/2007 was the last time the lake gained any water.
December 17th, 2007 at 11:21 am
The lake will not be rising any further from this rain. The only reason it rose the last two days is because it happened to rain on a weekend when they don’t do the big releases. The weekday releases will be much more than the extra water from rain. Probably, though, there will only be one release per day for the next week or so just like after the last rain due to extra water from the rain down stream. But a 6 inch rise? Not a chance.
December 17th, 2007 at 12:16 pm
Jay Randal - “a 2 inch rainstorm has no benefit to recharge the reservoir”
Somehow I think you just don’t understand the impact of drought deficit and the amount of moisture over time it will take to overcome the drought deficit. Droughts are long term situations. They take a long time to develop and a long time to resolve. If they do. Here is a good web page to get a relative drought understanding - http://www.droughtscore.com/about/Methodology.aspx
If the soils had been truly saturated by the earlier 1″ rain as you said, there would have been some flooding. Why? Because saturated soils can no longer handle any moisture. 2″ is of benefit, but its contribution is dwarfed by the demands of soils and plants due to the long standing moisture deficit. That is why in the arid west , water companies remove many trees and plants from along rivers and streams. The soil and plants get the water first. But as they are recharged, more water becomes avail to recharge Lanier.
You probably have seen this page but if not please take a look on this webpage how the US Weather Service includes a soil moisture measurement in the different drought stages - http://www.lawrencevilleweather.com/drought.html
As far as stream flow, I think that virtually all the available water from the recent rain will be in Lanier by tonight. Stream flows in most of N GA have been dropping for the last half day. Here is an interesting webpage with real time stream flow measurements that will help you understand the time it takes for water to move through a drainage, just click on the dots - http://waterdata.usgs.gov/ga/nwis/rt/
Their home page is good too - http://ga.water.usgs.gov/

rkolter
Thanks. But I think it was my mistake. Sorry.
December 17th, 2007 at 3:53 pm
At the beginning of the blog it stated that 0.01 is 1/10th of an inch. Isn’t 0.10 a tenth of an inch?
richard
December 17th, 2007 at 3:56 pm
It was 0.01 feet, which is 0.12 inches, or around 1/10 of an inch.
December 17th, 2007 at 6:00 pm
I’ve been watching the precipitation and the Lanier water levels very closely. From observing the lake elevation trace, this much I can state with reasonable confidence: Given the parched nature of the river basin above Lanier, and the amount of rain required to saturate the ground, I would suggest that the slight, incrimental rises in lake elevation are immediately attributable to the effect of the rainfall falling into the lake, NOT from an increase in inflow.
I had observed this effect on approx Nov 15 when 1.2 inches of rain fell at Buford dam, and the lake elevation increased by approximately .10 feet, a rise which ended when the rainfall ended.
This effect has been noticable on other dates of lesser rainfall as well: Nov 21, Nov 26, and December 15.
I think that the rainfalls around Lake Lanier have been contributing in any appreciable way to the inflow of the lake, and thus to a more sustainable rise.
However some of the rainfalls to the south (Eg: At the Coast Guard dock at Eufaula showed a rainfall of +2.5 inches. WF George Lake just downstream showed a jump from 186.6 to 187..18, which must reflect not only the 2.5 inches rainfall, but some increased inflow as well. The elevation level jumped around a bit after, but may have rounded out at a max elevation height of 187.25.
December 17th, 2007 at 8:37 pm
What you WILL see as a result of the increased inflow is a slight reduction in the rate of loss for the next day or two.
December 18th, 2007 at 12:59 am
notanumber > as long as ACE keeps releasing loads more water than inflows into Lake Lanier daily, thus no real way to determine the rise from the last rainstorm. As for taking a few days for the watershed to flow into the lake, I used info from an ACE hydrologist who claimed a 2 to 3 inch rainstorm can raise lake level about 6 to 10 inches and takes a few days to accumulate.
I have not seen any posted rainfall amounts from the last storm for areas north of Lanier that drain into the reservoir. AJC newspaper claims 2 to 3 inches fell in parts of Georgia. My yard in Stone Mountain got 1.40 inches.
As for how long to refill the lake when drained completely? Took 3 years after Buford Dam was built to fill it, but with drought could take longer. If Georgia starts getting heavier rains, then the drought will lessen in severity.
Also as long as we concentrate on watching Lanier levels, then ACE gets away with releasing more water to recharge Lake Seminole at Florida border. The daily release of 3+ billion gallons from Woodruff Dam is robbing the upper reservoirs to feed that flow.
December 18th, 2007 at 1:17 am
Jay Randal - “I used info from an ACE hydrologist who claimed a 2 to 3 inch rainstorm can raise lake level about 6 to 10 inches and takes a few days to accumulate.”
There we are again with the Corps.
Jay Randal - “If Georgia starts getting heavier rains, then the drought will lessen in severity”
I was wondering about that. Thanks for the info.
December 18th, 2007 at 2:12 am
Over the next 4 months > January through April > then we will know if the drought is getting worse or easing. At present ACE outflows from Lanier are about 50% reduction from a couple months ago, but as summer gets closer the outflows will increase if Florida insists the 3+ billion flow continues from Woodruff Dam/Lake Seminole.
December 18th, 2007 at 10:36 am
For those who don’t normally watch Lanier closely, the pattern is generally that the lake level drops through the summer and fall. Now is about the time the lake generally starts rising to it’s springtime peak. I can’t tell you if it is generally because of more inflow, less usage and evaopration, or what - just that this is the typical pattern.
This spring we peaked at around two feet below full pool even after a dry year last year. Now it is 20 feet below full pool. The lake has to start refilling soon. Even if it rises ten feet by spring, that will leave us ten feet below full pool to start the year. We may be lucky to get that.
Luckily yesterday Sonny bargained with the governors of Florida and Alabama and got - Zero reduction in flow!!!! Way to go Sonny - That will solve the problem!!!!!!
December 18th, 2007 at 1:23 pm
Jay Randal - “Over the next 4 months > January through April > then we will know if the drought is getting worse or easing. ”
Well, you know what they say about denial… Jay, the drought has been getting worse for over a year now. It is and has getting worse for months. What is your criteria for deciding the drought easing? Above average precipitation? The weather forecasters are calling for winter (a normally dry period) to be drier than normal. Why do you you want to push it another 17 weeks before you make up your mind? And what will you do if you decide it is getting worse? Whatever that is, why not do that now?
December 18th, 2007 at 1:52 pm
RKolter - I would respectfully submit that a .35 inch rainfall on the parched terrain in the basin above Lanier will have zero effect on the inflow into the lake. That .35 inches of rain got slurped up by the dry soil and desperate weeds.
I’ll leave it to the hydrologists to tell us what rainfall is needed in northern Georgia to increase streamflow, but I’d venture it is much more than .35 inches.
December 18th, 2007 at 2:04 pm
Actually I have heard a different take than some of you are putting forward regarding the dry ground. An article I read some months ago said the dry ground actually forms a crust which takes rain over quite some time to penetrate. The scientist interviewed for that article said the dry ground actually caused more runoff not less. Anyway - that’s a small point.
COE has new forecast data posted today. Forcasting another four foot drop over the next month. http://water.sam.usace.army.mil/lanfc.htm
Lanier just doesn’t have enough water to keep the river flowing at these unnatural levels.
December 18th, 2007 at 2:38 pm
RichS - I’ve been watching those forecasted lake levels as well. The forecast one month ago looked as ominous as the present forceast, even though the reality was less than a two foot drop in the last month. Even the shape of the forceasted lake level drop looks the same. I’m beginning to think the ACE is simply shifting the old forecast curve rightward on the chart, regardless of actual conditions on the ground.
December 18th, 2007 at 2:39 pm
I don’t see how they can forecast a 4 foot drop with an average of 0.07 feet a day for the last few weeks. The ACE may be planning to ramp up releases again.
Tim - I’d agree with you but the data just doesn’t follow. After a rain, the following day or two’s declines are less than normal, while the releases have held constant.
December 18th, 2007 at 2:40 pm
RichS, Thank you for the link to the graph. At that rate in another Randal Unit (4 months) Lanier could be very near the 1035 level. At which point, according to Jay Randal, we will have an idea if the drought is getting worse.
December 18th, 2007 at 3:07 pm
I have been watching that graph for two+ years now and unfortunately their predictions have been pretty accurate. I have no idea what data goes into it but I suspect they have some idea what the expected inflow should be and what they are planning to release. A good rain can make it deviate from their predictions though as happened in late November which flattened out the downward curve since then. They may not factor in rain predictions? Who knows.
I’m loving the Randal Unit. I think that should be used in all future calculations. A little harsh - but still funny.
December 18th, 2007 at 3:11 pm
Rkolter - I would disagree with your conclusion and point directly to the data: the Dec 15/16 releases occuring around the time of the rainfall were significantly smaller than the weekday releases. Check USGS river level site.
http://waterdata.usgs.gov/ga/nwis/uv/?site_no=02334430&PARAmeter_cd=00065,00060,00062
December 18th, 2007 at 4:52 pm
Tim, remember that December 15 and December 16 were weekends - releases are less on weekends. Compare Thursday and Friday to Monday:
December 13 - discharge of 1287, drop of 0.07
December 14 - discharge of 1310, drop of 0.07
December 17 - discharge of 1289, drop of 0.05
Or compare the 16th with the 9th. Sunday to Sunday.
9th - 845 discharge, drop of 0.03
16th - 851 discharge, drop of 0.01
It’s not a huge dip. But, it’s there.
December 18th, 2007 at 5:05 pm
rkolter - Since the Corps controls Lanier’s discharge I have a hunch that they can come close to meeting their own projection.
It is a “rigged” game. They get to do both, the prediction and the reality.
Anyway, I hope they retain at least that level of competency.
December 18th, 2007 at 7:01 pm
I never suggested the game was rigged notanumber. You’ve got a disconcerting habit of putting words into my mouth. I only said that given the current rate is only a bit over a couple feet a month, to do four feet a month, they will have to go back to two discharges a day.
December 18th, 2007 at 10:37 pm
Has anyone figured out why they discharge less on the weekends? I wonder if it has to do with COE workschedules? I know that seems a little strange but why would downstream water needs be less on the weekend than weekdays?
December 18th, 2007 at 10:38 pm
And I hate to take up for notanumber, but rkolter I think he was making his own point - not quoting you.
December 18th, 2007 at 10:57 pm
rkolter - I was replying to your December 18th, 2007 at 2:39 pm post above in which you stating that you didn’t see how the Corps could achieve their predicted level drop. I was attempting to stress that the Corps gets to manage both sides of the “game” and is very able to have results that meet their predictions.
December 18th, 2007 at 10:58 pm
richs - “why would downstream water needs be less on the weekend”
I think that in the winter weekend tap water consumption is less.
December 19th, 2007 at 1:27 am
Lol notanumber > I believe the drought is already catastrophic, but I do believe the next 4 months will determine if the drought will ease or get even worse. If rainfall is way below average from January to April, then Lanier will probably be bone dry by mid or late summer.
Take out your anger on Gov. Perdue, since he seems to be brain-dead about it. Plus both our Senators act dumb about the drought as well.
If Lanier does end up empty, then it will be weird to watch Perdue and Crist fighting over the few million gallons of water still flowing daily down the Hooch river from the North Georgia mountains.
December 19th, 2007 at 1:53 am
Jay, I am not angry, it is interesting to me to “observe” people and their reactions to slowly growing chrises such as the historic and exceptional drought in the SE. The reactions seem very similar to Kubler-Ross’ 5 stages of death and dying. The threads in this blog resonate a lot of denial (stage 1) with some anger (stage 2) emerging particularly towards elected officials and “outsiders”.
I don’t mean to put words in your mouth, but your plan is not to do anything until April? How did you decide on January - April? And if you determine that the drought is not easing in the Jan - April period what will you do?
December 19th, 2007 at 9:06 am
notanumber > I did not infer that I am not doing anything personally about the drought till end of April. I am just making an observation that drought could ease or get even worse by then. Georgia government officials are in denial about it.
Worst case scenario: Lake Lanier is emptied out completely, by end of next summer, and thus the outflow tubes under Buford Dam are left open so whatever watershed from upper Chattahoochee river can flow out and trickle down to Florida. So let’s assume the remaining flow is 500 million gallons daily from the Georgia Mountains. That means all the downstream users would be fighting over that remaining flow. Metro Atlanta might get maximum 50 to 100 million gallons out of it daily. That is if Gov. Crist of Florida even allows it. That flow is not enough for power plants, so all of them would be forced to shut-down. Mussels below Woodruff Dam, at Lake Seminole, would die off. Economic panic would ensue in Georgia & Florida.
December 19th, 2007 at 9:22 am
notanumber > I use end of April as a reference point, because starting in May the temperature goes up and water use tends to increase. If the spring rains are way below average, then little recharge to Lake Lanier, thus the heat of summer months would finish off the reservoir.
Average Georgians will not react to the drought seriously until their lawns, plants and trees start dying from lack of rain/water. In May all that will start to occur unless the state gets heavy rainfall. Major water shortages would also kick in starting in May.
December 19th, 2007 at 1:12 pm
Jay Randal > Where’s the water?!
Except for a blip in the streams and a measured “rise” of about .03″ in Lanier late on the 15th and early on the 16th there is nothing so far. Other than the further continued decline of Lanier. Regardless of the false hope promised by the Corps representative who said that a 2″ rain would provide 6″=10″ rise or the “scientist” who said that once the ground was crusted by drought that even more run off would be available to the streams.
I point this out to stress that the situation is serious now and beyond the time frame remedy of large publics works projects. I also would not assume that the 500MGD is a given. Stream flows are at an almost historic low and are trending lower. If the near surface aquafiers continue to drain without recharge some of the streams may go all but dry.
It seems misguided to hope on an abnormally wet winter when all the forcasts call for it to be dryer than normal. It is too bad that the news does not prepare the “average Georgians” to understand today’s reality, rather than cooperate with the politicians.
December 19th, 2007 at 4:05 pm
All kidding aside, I need some help.
Jay, how tall is your head? I’m going to use it for a new measurement called the Randall-head (Rh) which I’ll use for depth calculations.
And if you give me it’s circumfrence, I’ll figure out the Randall-volume (Rv) which can be used for volume calculations.
We can still call one four month period a Randall, making three Randalls a year. It’d be better if a Randall was 2.4 months, giving us 5 Randalls a year, or 1/2 randall equalling 1/10th a year.
A Randall based time period is still in the works, based potentially on the average length of time between new blog entries, and the time it takes Jay Randall to respond with a comment about the coal plant in Florida.
Actually, this could be kind of fun. A Randall predictor, based on the rainfall of the entire planet NORTH of Lake Lanier, but below the arctic snow belt.
And the Randall economic water indicator - a value based on the volume of rainfall that falls in Alabama and Florida and Georgia, divided by three, then subtracting Georgia’s volume of rainfall. This value being the amount of water Alabama and Florida must donate to Georgia.
Sorry, I’m not picking on you Jay. I’ve had way too much caffeine and am punch-happy and this seemed like a fun thing to talk about.
December 20th, 2007 at 2:51 am
Lol whatever makes you slap-happy rkolter. Measuring my response time to posts would be boring, because I might be busy and not see it for a day or two.
As for the drought > use my 4 month increments. Jan to Apr, May to Aug, and Sep to Dec. Next 4 months determines whether the drought eases or gets worse. Then next 4 months determines whether Georgians panic about severe water shortages. Then next 4 months determines if half the population flees from the state.
December 20th, 2007 at 11:07 am
Hey Jay Randal, are you still expecting a 6″-10″ rise today or tomorrow in Lanier from last Saturday’s rain?
December 21st, 2007 at 10:03 pm
notanumber > as long as the storms weaken over Georgia, then I cannot make any more predictions of runoff benefit to Lake Lanier. Drizzle was all I got at my place in Stone Mountain the past few days, so no runoff from that.
December 21st, 2007 at 10:25 pm
notanumber > AJC newspaper claims 292 days more water in Lanier now, so they believe more runoff has entered the lake and/or the Corps is releasing less daily from Buford Dam to boost their clock run out time.
Did read a recent article that claims the Corps releases only 750 million gallons from Lanier now. Also the article claimed the 3+ billion required flow from Woodruff Dam, into Florida, is being supplied from other reservoirs on Chattahoochee River below Atlanta and from Flint River watershed.
December 21st, 2007 at 11:01 pm
Hey Jay Randal, my question was about the prediction of 6″-10″ based on last Saturday’s rain that you made at the very top of this thread as the first reply.
Was not asking about any other prediction based on any other rains.
As far as 292 days, so are you choosing to believe that number? Until the AJC shares the underlying algorithms so that the radical deltas they post can be understood I am very skeptical of their water “clock”. As far as lake level, the daily maximum level has been lower every day this last week.
December 21st, 2007 at 11:33 pm
I do not believe in AJC clock numbers, but just said it has gone up to 292 days now. I have no idea what reality they base it on, but AJC thinks every rainstorm is adding to the lake in capacity.
As for the previous storm it seems most of the dry watershed absorbed it before it could flow into lake. Plus I did see a posting that rainfall in north Georgia mountains was under one inch for that storm and not 2 plus as reported in news.
December 21st, 2007 at 11:45 pm
Jay Randal - “As for the previous storm it seems most of the dry watershed absorbed it before it could flow into lake.”
Yep, I tried to tell you that back on the 16th. So did Paul.
Jay Randal - “but AJC thinks”
I have no idea what they think, and don’t believe anyone outside the editorial staff and publisher does either.
December 21st, 2007 at 11:57 pm
notanumber > my prediction was based on a 2 to 3 inch rainfall in Georgia Mountains, above Lake Lanier, but the area actually received less than one inch of rain for that storm. That amount does not produce much runoff.
When Blue Ridge mountains actually get a 2 to 3 inches rainstorm, then we will see how much rise in level for Lanier.
Watershed for Flint River is below Atlanta, and Stone Mountain, so the 2 to 3 inches did make a difference for Lake Seminole at Florida border.
December 22nd, 2007 at 9:43 am
Note to Jay Randal, Facts are important things. It is not wise to make future predictions based upon past events that did not happen.
First you shift time span from Wens to Sat, now you want to shift place from Lanier to Lake Seminole.
December 22nd, 2007 at 10:42 am
notanumber > nope I stated the criteria for my prediction did not take place. Storm that was supposed to have produced over 2 inches of rain in North Georgia mountains did not take place. Less than a inch occurred, thus not much runoff from watershed into Lake Lanier.
I believe you like to argue no matter what over trivial matters. The rain that did occur soaked into the dry soil before reaching the lake, so pat yourself on the back for that, but at same time my criteria for recharge water for the lake did not occur because less rain fell than what was reported to have fallen.
Rain of less than a inch is practically worthless for any benefit to Lake Lanier. As long as ACE releases more water daily than flows into it, thus the lake cannot refill. That is the issue and nothing else matters.
December 22nd, 2007 at 12:26 pm
Jay Randal states - “As long as ACE releases more water daily than flows into it, thus the lake cannot refill”.
There are other issues that affect the capabilty of Lake Lanier to refill. Some municipalities remove water dirrectly from the lake and, as the weather warms in the spring and summer months, surface evaporation will remove a greater amount of water that will not have the opportunity to be released by ACE.
Also, while probably not an important issue yet, Lake Lanier is slowly filling with silt, further reducing the total water storage capacity.
December 22nd, 2007 at 4:47 pm
Jay Randal > In the top post of this thread you wrote as fact after the rain storm the following “After a good soaking rain, like last night, it will take a few days for the run-off of watershed to flow into Lake Lanier. ” Now you are syaing that you didn’t know anything about the rain. Yet last weekend you claimed to observe it by calling it a “good soaking rain” that would take a few days “to flow into Lake Lanier”.
Now you say the rain did not occur in Lanier’s catchment area. Very good, but I (and probably many others since it is on the USGS pages) knew that days ago. You could have too. So, my question is why did you post about the rain as a personal observation (”good soaking rain”) of fact? And how much of what you post here, to be polite, is similarly misguided?
I recognize that predictions are just that, predictions. As Yogi Berra reportedly said “predicting is difficult, especially about the future”. But, most useful people at least try to base their future predictions on events that have actually happened.
December 22nd, 2007 at 4:55 pm
Coelacanth6 > Another factor that affects lakes and rivers is the water usage of biomass. Each one of the mature pines, estimate 30 gals per day during spring/summer. Mature deciduous tree anywhere from 100 - 500 gals (depending upon species per day) in the same season. And don’t forget all the grasses, forbs, shrubs etc. Those wild plants just like the domestic ones in residential yards need water. That is why there are almost no trees and shrubs permitted to be growing along irrigation canals in the arid SW.
