Dam was built in the 1970’s
Property was purchased and homes built on the promise of a full & beautiful lake.
Skepticism arose and many doubted the lake would ever be realized.
Land values were low and property was available via sheriffs sale.

Troy, I checked in several water quality manuals concerning alkalinity and hardness. The following statement should assure that your pumping operation will have no negative impact on the fish population in Beaver Lake. The statement is as follows: "Fish grow well over a wide range of alkalinities and hardness, but values of 120 to 400 parts per million are optimum". From that statement and the values you provided me you are good to proceed with the pumping. You should be complimented on doing your research prior to any action as we usually are contacted after the fact and there is a problem. Best of luck filling the lake and hope we get more rain.

HHS LETTERHHS LETTERTroy,I had a couple people look at the numbers, and they don't see anything that should cause any problems. To be really sure you should probably run this by your engineers that designed the plant. They should be able to tell you what you will be able to handle.I hope that helps. If you have any other questions. Let us know.
