Phosphorous and water quality subject of annual Moose Mountains Greenways cruise

WOLFEBORO — More than 50 guests participated in the Moose Mountains Regional Greenways' 3rd annual "Water Quality Cruise" held recently on the Winnipesaukee Belle Charter Boat. Participants enjoyed the scenery, refreshments and live traditional music as they cruised around the south end of the lake.
When a quiet lake area was found, the boat stopped for a lively presentation by Pat Tarpey, Executive Director of the Lake Winnipesaukee Watershed Association (LWWA). Tarpey explained the effects of phosphorus loading on the water quality of the lake. Phosphorus is naturally present in soils and undesirable algae blooms occur when phosphorus levels are elevated as a result of silt carried into the lake due to erosion. LWWA has examined land use patterns within several sub-watersheds around Lake Winnipesaukee and measured the phosphorus levels in the associated lake coves and bays. The work reveals that areas with the greatest density of forests do the best job of controlling the flow of phosphorus into the lake.
