Indian River Bay
Background The Indian River Bay watershed is a subwatershed of the Indian River Bay. Indian River Bay makes up one of three of Delaware's Inland Bays. The Inland Bays consist of three interconnected bodies of water - Rehoboth Bay, Indian River Bay, and Little Assawoman Bay - all located in southeastern Sussex County. The land use of the watershed is made up primarily of agriculture and wetlands.
Water Quality There are nutrient and bacteria TMDLs for the Indian River Bay Watershed which requires a 40% reduction in nitrogen and phosphorus, 40% reduction in freshwater nonpoint bacteria, 23% reduction in marine nonpoint bacteria, and a cap on point source bacteria at a geometric mean concentration level of 35 CFU enterococcus/100mL. This watershed has sites sampled for a consistent suite of environmental contaminants. These contaminants are broadly classified as Volatile Organic Compounds (VOCs), Semi-Volatile Organic Compounds (SVOCs), Pesticides, Polychlorinated Biphenyls (PCBs) and Metals as listed using USEPA and DNREC defined standards. When sites are adjacent to water bodies sediment samples are collected to assess potential impact from a site on the health of the waters. Learn more information specific to this watershed from the DNREC Advanced Facility Search Tool.
Plants and Wildlife Delaware's Department of Natural Resources and Environmental Control (DNREC), Division of Fish and Wildlife conducts on-going inventories of natural communities as well as rare and declining species, (e.g., state and globally-rare plants, birds, insects, mussels, reptiles, and amphibians). It maintains a database, both electronic and manual, of its findings throughout the state. Learn more about the wildlife and plant communities in this watershed from the DNREC Division of Fish and Wildlife Conservation Programs. In addition, the Division of Fish and Wildlife, working with the University of Delaware's Institute for Public Administration - Water Resources Center, maintains online databases about plants and plant communities in Delaware. Learn more about the plant communities in this watershed from the DNREC Division of Fish and Wildlife.
