Basically, the information on the site you referenced was very
special. It assumes that the drought conditions that existed prior to
October 2005 have no bearing on the groundwater table and that only
information since that date is worth studying. Also, it bases all its
information on Brookhaven rather than Ronkonkoma so your assertion
that he claime the Lake Ronkonkoma area got 31.5 inches of
precipitation is misleading at best.
I have updated this topic to include the data from NOAA (National
Oceanic & Atmospheric Administration) for Ronkonkoma and Brookhaven
for the period in question so you can judge for yourself what kind of
propaganda is being spread by the political forces who want you to
believe that nothing can be done to help us and that all of our
problems are due to rainfall.
SCWA consumption has doubled since 1987 while the population only grew
by 1.5%. SCWA does change well productions and interconnect wells in
their delivery system. They also make delivery system adjustments when
they take over other water companies. The majority of homes north of
the lake and south of the divide are mostly on 1/4 acre plots. The
clay Lens tends to be 50' below the surface. The groundwater
elevation just north of the Mall and south of the divide is
approximately 10 feet higher than at the lake. Well 1812 is about 1/2
mile west of the lake and. The Brown's Road Pumping Station is
directly south of the Mall & directly north of the lake. Every inch
of land north of Lake Ronkonkoma up to the N/S water divide is
developed with the exception of the Bog & 60 acres of old forest just
north of the lake. According to SCWA & the USGS water does travel
horizontally at the rate of one foot a day from the divide to the
lake.

gives groundwater elevations.
