The Vermont Department of Environmental Conservation is seeking input on proposed phosphorus cleanup plan for Lake Memphremagog

On Tuesday November 15th from 2:00 to 3:30 at the East Side Restaurant, 47 Landing St in Newport, The Vermont Department of Environmental Conservation will be seeking input on proposed phosphorus cleanup plan for Lake Memphremagog that will be the basis of a Total Maximum Daily Load (TMDL).

Phosphorus levels in the Vermont portion of Lake Memphremagog are above the water quality standard and contribute to cyanobacteria blooms as well as excessive plant and algae growth that limits the quality of the lake for recreational use.  Modeling of phosphorus runoff from the Lake Memphremagog watershed estimates that much of the phosphorus load is coming from agricultural lands (45%), developed lands  which contribute 23%, with an additional 20% from stream channel instability and 12% from natural sources.  Modeling also estimates that loading from these sources needs to be reduced by 29% for the lake to meet its water quality standards.

 

At this meeting proposed phosphorus reduction targets for each of these land use sectors will be presented along with control strategies including regulatory programs, technical and financial resources that are needed to support municipalities, individuals, farmers in meeting these loading reduction targets.  Attached is a summary of the TMDL proposal that will be discussed at this meeting.

 

Ahead of the TMDL meeting from 1:30 to 2:00 at the same location, the Memphremagog Watershed Association will present the results of a stormwater master planning study for the Lake Memphremagog Watershed that has identified several projects to reduce stormwater runoff in the watershed including the towns of Barton, Orleans, Derby and the City of Newport.  These projects will be  priorities for future grants to reduce phosphorus loading to Lake Memphremagog.

ByMWA

In the Lakes and Ponds Program, we are geting reports of very high-water levels in many lakes and ponds across the state and related property damage, including Peacham Pond, Joe’s Pond, Lake Dunmore, Shadow Lake (Glover), Lake Elmore, Woodbury Lake, Valley Lake, Sabin Pond, and various reservoirs. I am sure there are many others, and this is not an exhaustive list. It is always useful to hear from people about what is going on after the storm at individual lakes, so don’t hesitate to reach out and share information and photos.

How Vermont’s physical and human geography help explain recent flooding

How Vermont’s physical and human geography help explain recent flooding

ByMWA

Vermont’s physical features affect its weather, its rivers and how humans have come to inhabit it.
When flooding hit Vermont this month, destruction spanned the length of the state, from Windham County up through Northeast Kingdom.

But the series of storms did not damage regions equally, with many mountain towns and riverside communities bearing the brunt of the impact.

The precipitation itself, as well as the flood-prone nature of many Vermont towns, can be explained by the state’s physical features, experts say. The Green Mountains along the state’s spine determined where Vermonters settled, where they worked and the weather they endured.
