This document outlines federal and state efforts to achieve the binational phosphorus load reduction targets adopted in 2016 under the Great Lakes Water Quality Agreement.
The United States and Canada adopted phosphorus load reduction targets to combat Lake Erie algal blooms.
Pennsylvania outlines actions to reduce phosphorus in Lake Erie.
Canada and Ontario outline actions to reduce phosphorus loading to Lake Erie.
The Great Lakes Water Quality Agreement (GLWQA), signed by Canada and the United States, is a commitment to protect the waters of the Great Lakes. It was most recently updated in 2012. Annex 4 was formed to manage phosphorus concentrations and loadings (and other nutrients if warranted) in the Great Lakes.

Tributary monitoring data was used by the USGS, NCWQR, USEPA and ECCC to calculate spring and annual phosphorus loads. Annual loads were estimated at the river mouth using tributary monitoring and municipal discharge data from NCWQR, OEPA, MDEQ, USEPA, USGS, ECCC, and OMECC.
As large-scale restoration plans for degraded aquatic habitats evolve, it is essential that multiorganizational collaborations have a common vision to achieve consensus on restoration goals. Development of restoration targets and postrestoration monitoring strategies can be focused using a viability analysis framework that supports an adaptive management process. Resource managers in the corridor can use these results to identify knowledge gaps, research and restoration priorities, and to assess progress towards meeting restoration goals.
The Coastal Assembly pursues strategies to improve collaboration, establish basin-wide conservation goals, track progress, and adjust actions on a regular basis.
The five main strategies are described below:
