In 2007, the Ohio Environmental Protection Agency convene the Ohio Lake Erie Phosphorus Task Force to identify and evaluate potential point and nonpoint sources of phosphorus to Ohio tributaries; determine what practices may have changed since 1995 that could increase dissolved reactive phosphorus (DRP) loads; examine various aspects of agriculture that might influence the increase in DRP loads; review the possible/probable relationships of the increased DRP loads to the eutrophication problems that have returned to Lake Erie (particularly the western basin); consider the impacts of zebra and quagga mussels in altering the internal cycling of phosphorus in the lake itself; determine if these issues were unique to Lake Erie or occurring on a broader basis; identify research and monitoring needs; and recommend management actions that could be implemented to alleviate current conditions. They published their final report in 2010.
