Conowingo Reservoir Infill and Its Influence on Chesapeake Bay Water Quality

Workshop participants identified a set of 9 recommendations for immediate (next six months) and future management actions regarding Conowingo infill.  Overall, the report recommends that the existing body of research and monitoring data be used to constrain model simulations of the future behavior of Conowingo dam, in order to assist partners in efficiently achieving the TMDL.  Further, the report expresses support for sustained studies of Conowingo infill that are a combination of monitoring, data analysis, process research, and modeling, and seeks to identify high priority science needs.

The recommendations can be summarized broadly below:

1. Address biogeochemical processes related to sediment scour and nutrient cycling that may influence bioavailability in reservoir sediments, under variable flow ranges in the Conowingo Reservoir.

2. Ensure representation of effects of Conowingo inputs to Chesapeake Bay for the full range of flow conditions including ‘extreme’ high-flow events.

3. Improve representation of reactivity of particulate organic matter in Conowingo outflow.
