Phosphorus Load to Lake Champlain from Vermont, (2001-2010)
Current Value
631 metric tons/year
Definition
Story Behind the Curve
With the passage of the Vermont Clean Water Act, total maximum daily load phosphorus levels were established to monitor improvement in the health of Lake Champlain. Phosphorus concentration is currently 631 metric tons (MT/year), which does not meet EPA water quality standards. The loads and targets are established for the point source wasteload allocations (WLA) and the non-point source load allocations (LA), along with a margin of safety (MOS) for 12 lake segments. Please see http://www.epa.gov/region1/eco/tmdl/lakechamplain.html for more information.
Why Is This Important?
Lake Champlain is an important ecological, cultural, and economic resource for Chittenden County that is threatened by excessive phosphorous levels which negatively affect the health of Lake Champlain by promoting too much plant and algae growth and depleting available oxygen in the water.
