Water Quality Monitoring Report

The Secchi Disc is the most commonly used device for determining water quality. It is an 8” diameter disc with alternating black and white quadrants. It is lowered into the lake on a tether and the test is to see how deep it can be lowered into the lake and still see it.  The observer uses a scope which is much like a swimming mask to observe the disc.

A program called the Secchi  Dip- In is run by Kent State University in Ohio and they collect data from all over the country and in many foreign countries as well.  Over the years this data has been catalogued and one can compare the data from their lake with those all over the country.  Great East Lake is one of a small percentage of lakes which has had an average secchi disk reading in the vicinity of 10 meters.  A national average might be more in the vicinity of 2 or 3 meters.

Water Quality Monitoring Report
Written by Chuck Hodsdon   

The lake monitors for this year as for the past several years were Chuck Hodsdon and Dave Lafond, with occasional help from our wives. We also made one trip as we do every year with a team from UNH as they make some additional measurements with much more sophisticated equipment than ours. We also made one trip with some youngsters so that they could see what we were doing to test the water quality in the lake. We found that the youngsters could see our Secchi Disk somewhat deeper in the lake than we could and our wives disagreed with us on the colors of the alkalinity indicator. (Alkalinity is based on a vague blue to gray to pink color change as acid is added to the water.) Have no fear. When Dave and I compare our data with the professionals from UNH we are usually right on.

Thrills and Chills - Fireworks on Our Lakes
Written by Chuck Hodsdon   

Excerpted from "Lake Tides, a Univ. of Wisconsin publication

"It was a black and sultry night. Not a breath of air was stirring. The lakes surface was as flat as glass. The first starburst lit up the sky in a wild and sizzling display of crimson and white. The water mirrored an exact duplicate, doubling the visual thrill… The Independence Day celebration had begun."

Water Quality Monitoring 2006 Great East Lake
Written by Chuck Hodsdon   

This summer we managed to monitor 4 sites on a consistent basis for the whole summer beginning in June and continuing until October. We continue to send our data and samples for study to the Lakes Lay Monitoring Program at UNH. In addition we will be sending our data to the Volunteer Lake Monitoring Program operated by the State of Maine. Chuck Hodsdon was recertified at a workshop in early May by the VLMP in Maine. In addition we had a team from the Freshwater Biology Group from UNH visiting Great East Lake this summer as we have done for many years to collect more extensive data on the condition of the lake.
