Erosion control project improves Lake Iroquois feeder stream

The Lake Iroquois Association partnered with the Vermont Department of Environmental Conservation and the Vermont Youth Conservation Corps this summer to restore the floodplain and control sediment from of one of the muddier streams that feeds the lake.

Lake Iroquois is fed by 10 streams that flow through its border towns of Williston, Hinesburg, St. George and Richmond. The streams carry pollutants like nitrogen and phosphorous into the lake. According to association director Pat Suozzi, the stream near Pine Shore Drive in Hinesburg has proven, over 40 years of water sampling, to be one of the most polluted of the lake’s feeder streams.

The state provided a $34,000 ecosystem restoration grant for an erosion control project on the stream. Regional Watershed Coordinator Karen Bates and River Scientist Gretchen Alexander created a plan for the project, and Vermont Youth Conservation Corp Director Daniel Schmidt organized work crews to implement it, alongside volunteers with the Lake Iroquois Association and the Pine Shore Drive homeowners association.

More than 100 native plants were planted to anchor the stream bank, culverts were improved or removed, stones were placed for erosion control and timber dams were installed to slow runoff and capture sediment before it enters the lake. Also, Pine Shore Drive was re-graded to better manage runoff.

The Lake Iroquois Association is a collaboration of the lake’s four surrounding towns that works to maintain and enhance the lake ecosystem and public uses. The association works on water monitoring, research, education, management and advocacy involving lakefront property owners, municipalities and state and federal agencies.
