>Had an excellent fall season for the lakes with the West Oakwood freezing over on
December 7, 2009 with good ice. But then came the Christmas snow storm
dumping Lots of snow on top of the ice. Oxygen test on Saturday December 19,
2009 was 11 ppm. December 29th tests were 9 ppm. Then another accumulation of
snow the 1st of January and below zero temps. Then January 10 oxygen test
dropped to 3 ppm due to the extreme snow cover on the lake.
>> Tuesday January 12, 2010 Roger Bommersbach, Doug Leighton and Larry
Wittmeier began work of cutting one section of ice out to place one floating
aeration unit into the lake. On January 13th they installed the second aeration unit.
Both of these aerators are plugged into 220V and operating. One unit is plugged
into 220 outlet from the Bommersbach's residence and the other unit is plug into
Peterson's 220 outlet. As per year ago utilities these units cost approximately $3.00
per day to run or about $180.00 per month which is paid for by the Oakwood
Lakes Development Association. These units were placed on the northwest area by
Boiler Pass on Tetonkaha Lake of West Oakwood. With the operation of these two
units forcing oxygen into the lake and movement of the lake water will cause thin ice
in that area. A number of "THIN ICE" signs have been placed in the area where
these two aerators are located.
>>>The main aeration system, on West Oakwood, is operating with both motors
sonce Dece,ber 9, 2009. With the addition of the two aerators installed this past
week, it is hoped that it will keep the oxygen content in the lake from deteriorating
further and thus be able to save the fish population on West Oakwood. Oxygen test
will be taken over the course of the next 6 to 8 week to track the oxygen levels since
installing these two aerators.
>>>>The *aerators just installed, consists of an electric motor drive above the
water surface on a float mounting. The motor is connected to a hollow shaft within
a protective housing positioned at a 45 degree angle downward into the water. The
shaft is connected to and drives a propeller beneath the water surface. The propeller
thrust the water past the diffuser, drawing air through intake holes above the water
surface down through the rotating hollow shaft and diffuser into the water.
