2010 Summary

AIM worked on the Chateaugay Lakes for the first time in 2010. An eight diver crew was brought in for 2 weeks to tackle dense areas in the connecting channel between Upper and Lower Chateaugay Lakes. The milfoil growth was extremely dense and tall resulting in lots of mass. As a result the crew harvested 22.5 tons of milfoil in two weeks. There is much to be done on the Chateaugay Lakes as they are facing one of the worst Eurasian milfoil infestations in the Adirondack Park. AIM hopes to employ new methods and technologies in the future to control the lake’s large-scale problem.

The following are four maps generated by Dr. Dan Kelting of the Adirondack Watershed Institute (AWI) detailing the extent of the milfoil growth on Lower Chateaugay Lake, the Channel and Upper Chateaugay Lake as well as the specific area where AIM worked in 2010. Current milfoil growth is shown in green. The red line indicates the boundary of potential milfoil growth if left unchecked. The final map shows transect lines used by AWI to monitor the milfoil growth over time.

The following maps show Lower, the Narrows and Upper Chateaugay Lake.  The AIM work area in 2010 is boxed in red on the Narrows.  The final map is a closeup of the AIM work area.
