Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Solar Pump - worth the $?

So my 8.5 acre lake is running low again this year, seems like 2 of 3 years we are running drought conditions in my part of Texas...

My brother came up with the idea of a solar pump. After doing the math - its clear that no solar pump will draw enough water to fill the lake, however one model I looked at will supply about 33,000 gallon per day.

The idea is that over time the lake will fill with rain and then the solar system would keep up with evaporation and theoretically keep the lake full. It seems too good to likely be true...

Your thoughts?
