The Bay provides significant economic and recreational benefits to the water catchment’s population, estimated to exceed USD 33 billion annually (U.S. Environmental Protection Agency, 2010a). While total pollution levels have declined since 1985, most of the Bay’s waters are degraded and are incapable of fully supporting fishing, crabbing, or recreational activities. Algal blooms fed by nutrient pollution block sunlight from reaching underwater Bay grasses and lead to low oxygen levels in the water.
