These rivers are the Susquehanna, Potomac, James, Rappahannock, Appomattox, Pamunkey, Mattaponi, Patuxent, and Choptank. The RIM stations are located near U.S. Geological Survey (USGS) streamgages to permit estimates of nutrient and suspended sediment loadings and trends of the amount of constituents delivered downstream. The USGS partners with the Maryland Department of Natural Resources, and the Virginia Department of Environmental Quality for the collection and analysis of RIM network data."

     "text": "Issue: The amount of nutrients and suspended sediment entering the Chesapeake Bay affect water-quality conditions in tidal waters. Excess nutrients contribute to algal blooms that lower the oxygen levels in tidal waters that are important for fish and shellfish. The algal blooms, along with suspended sediment, also decrease visibility in shallow waters for submerged aquatic grasses. The grasses are important because they put oxygen into tidal waters, provide habitat for fish and crabs, and food for waterfowl."
