The Dam Spillway Project
In 2012 we suffered a major drought, combined with a dam spillway leakage problem that had been steadily increasing over decades. The water level was so low that many of the coves in the lake were dry dirt, accessible to walk across.
No work had previously been done on the spillway from it's inception in 1973 thru 2013.
PHASE ONE of the Spillway Project was completed in 2013, and major improvements were made to the spillway by means of a grout curtain across the entire spillway. The water seepage was been reduced from 4000 GPM (gallons per minute) in 2013, down to just 750 GPM during April 2017.
PHASE TWO of the Spillway Project was underway (April 2017)
A three-man professional geotechnical dive team went into the water during April 2017 to inspect and videotape the interior (lake side) face of the limestone formations at the spillway or what Lakewood Residents refer to as “The Rock”. With the implementation of Phase Two, the goal is to reduce seepage through the limestone down to a final acceptable rate of 100 GPM.
The mission was to try to find the lower pressure inlet of lake water in the face of the Limestone. This can lead to a simple and economical fix to block the inlet. If we are unable to locate the inlet(s), then we will commence with the final grouting as planned to seal off the seepage.
