Hi All,
The following data regarding our recent regional rainfall and it's effect on the Water Table may prove interesting.

RAINFALL AND THE WATER TABLE

David, if I understand well your research, buying our 750,000 gallons a day could maintain our lake level at this height or even better. Why don't we do it? Does the County have sufficient recycled water available on a daily basis to provide us with what we want?
In 2008, the County gave us 80% of the water we bought in 2 months ( May and July ). I am trying to find data from Water Management as to their daily production and its distribution. Can you help in this regard. Thanks Andre
Correction to my last post; May and June instead of May and July. Andre
Hi Andre

I am putting together a report using all of the numbers available on this issue. It will include all information such as Evaporation, Percolation/seepage, mean Rainfall, Irrigation losses, impact of Water table variations on closed lake seepage....Etc.
This is a non-trivial project, and since it is not my assigned UCO area, it will probably be ignored, but I will write the report anyway.
Preliminary indications are that IF we received our contractual cap of 750K gallons DAILY we would indeed, albeit slowly, bring the lakes up to a reasonable level all year long.
Have you taken a reading of the level gauge at the effluent pipe recently?
Thanks,
Dave Israel
Dave - Level? The meter reads today 173,767,960 (last 6 on way to 7). Water not flowing.
The new ruler stuck in wet hole in sand reads 2”. It is next to, and lower than the concrete slab for the old white, brown, blue vertical pipe.

It's the reading on that pipe ruler I was asking about.
That is the level above NGVD and can be used to correllate with the USGS site data to compute the effect of the water table on Percolation/Seepage.
Also of course it will give us a feeling for the net impact of the rain event on Lake Levels.
I will make a Field Trip.
Thanks,
Dave Israel
