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.
17 Aug 2006

Lake filled in 1976.
Property values increased & Beaver Lake
was finally a good investment.
An entire community grew as the
result of the lake.
The number of residents increased
steadily after the lake filled.

Troy,
Letter From Game and Parks
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 LETTER
Troy,
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.
