Kelso Lake, is actually a reservoir about 80 acres in size. One area of the lake is used for recreational swimming, while the other end of the lake is used for fishing, canoeing and boating. 

The client was mainly concerned about water clarity issues. The water level in the lake was temporarily lowered to accommodate nearby bridge construction, and was expected to last about 2 years. With the lower water levels, the water clarity was not as good as it had been in previous years. 

We did not do our regular pond assessment because the client was specifically interested in adding an aeration system. They provided us with detailed depths and measurements of the area where the aeration system was to be installed.

From the information provided to us by the client, we first devised a plan for the placement of the diffusers. Then, we determined that a 1 HP Rotary Vane Aeration System with 6 diffusers, 800′ of 3/8″ weighted airline tubing and 400′ of 5/8″ weighted airline tubing was required to meet their needs. The lockable cabinet was to be placed beside a small building with electricity, about 40′ from the shore.

Since the staff at Kelso had the machinery and manpower, they dug a trench from the building where the compressor cabinet was located, to the waters’ edge. The weighted airline tubing was buried in this trench to hide it from sight. Once we laid the 6 lines of airline tubing in the trench, we hopped aboard the boat to place the diffusers. 

The picture above shows 4 of the rotary vane aeration system diffusers placed behind the swimming boundary buoys.
