Fall 2009

   

Good Clarity, Algae Alert in Preliminary Summer Report

Secchi disk transparency (a measure of water clarity and light penetration) between Memorial Day and Labor Day was very good again this year. Water clarity readings were taken once a week all summer by our summer intern and once a month by our scientists from Ecosystems Consulting Service. The range of water clarity depth readings was from a low of 7 feet to a high of 14 feet.

However, this improved clarity and light penetration also helped spur aggressive weed growth and floating algae accumulations in shallow shoreline areas, especially at the Sucker Brook outlet.

The lake restoration systems were turned off at the end of September. With lake turnover occurring, phosphorus and other nutrients will mix up from the bottom layer of the lake. We expect this to feed a fall algae bloom.

When we receive our full annual report on the results of our lake monitoring program from Dr. Robert Kortmann, we will provide more information on the 2009 season on this site.


Invasive Removals Highlight Joint LWTF/LWA Meeting

The annual joint meeting of the Task Force and the Lake Waramaug Association was held on Sept. 13 at the Lake Waramaug Country Club.

Bruce Lockhart of Water's Edge Restoration & Management presented a comprehensive overview of the lake's invasive plant removal program, providing aerial photo documentation of invasive plant locations and areas where the plants have been removed. Lockhart was retained by the Task Force in 2006 to oversee the removal of invasive plants from Waramaug. He explained what divers do in removing and covering plants with bottom barriers (benthic barriers) and reported that locations where barriers were placed last year showed no signs of invasive plant reappearance.

Mr. Lockhart indicated that all known invasive plant locations had been hand-removed or covered. However he cautioned that due to the soft sediments in the lake, the small size of the plants and areas of poor transparency; he can never be certain that all plants have been removed from all locations.

Save the Lake — "Leaf It Alone"

It's that time of year again, and the autumn leaves are falling... When you rake up leaves, arenít you always amazed at how many leaves come off a single tree and the size of the piles it takes for a good fall leaf clean-up?

As pretty as they are, each leaf that washes into the lake releases a little nutrient storehouse. As the leaf decays it releases nutrients including phosphorous. Leaves raked or blown into the lake during fall clean-up will accelerate next year's shoreline algae and weed growth. Just what you donít want! If you hire people to rake your yard near the lake or feeder streams, please instruct them to make sure that leaves are removed or put in a compost area well away from the water.
