Zebra Mussels take hold in Lake Waubesa

As Lake Waubesa residents prepare for winter, the ritual of removing docks and boat hoists uncovered some unwanted guests.  The Zebra Mussels have moved in, once they are established, there is little that can be done to control them. 

Zebra Mussels feed on algae which can help improve water clarity.  That is where the good news ends.  Water clarity allows the sun to reach more bottom surface.  This enhances weed growth creating larger and thicker weed beds.  Less good algae means a smaller food supply for native organisims and small fish. 

Clear Horizon Manure Digester Spill

On November 24, a pipe from the Waunakee Community digester burst and began discharging manure.  The pipe failure released 300,000 gallons of manure.  The impacts of the spill are being monitored by the Dane County Land and Water Resources Department.  The spill was quickly contained and early evaluation of the spill indicate approximately 30 pounds of phosphorus will reach the lake.  This amount is minimal compared to a 1.5 inch rain this past March resulted in 4,450 pounds of phosphorus registering at the same monitoring station.  For more information see:
