Background
Indian River Bay watershed 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 that are further divided into subwatersheds. The Iron Branch Watershed is a subwatershed of the Indian River Bay.
  
Land Uses
The land use of the watershed is made up primarily of agriculture and wetlands.
  
Nutrients and Bacteria
There are nutrient and bacteria TMDLs for the Iron Branch Watershed which requires a 40% reduction in phosphorus and nitrogen, 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 until all point sources are eliminated as required in the 1998 Inland Bays Nutrient TMDL Regulation.
  
Contaminants
The Iron Branch Watershed has one site listed in the Site Investigation and Restoration Section database. The one site is a National Priorities List (NPL) site.

The site is sampled through the program listed above 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.

If you would like to view reports for any of the sites in the SIRS program please follow the link the DNREC Environmental Navigator to search by map for the Iron Branch Watershed.
