Description Results of a 2013-2014 TMDL effectiveness monitoring study in the Henderson Inlet watershed indicate that fecal coliform bacteria (FC) levels are declining at the watershed and sites level. This FC reduction occurred despite an increase in human population in the watershed and an increase in parcel density within the urban growth areas. An assessment of two state funding programs indicates that between 1990 and 2014 a total of 40 water cleanup, restoration, or protection projects were implemented in the watershed. A comparison of projects implemented and water quality trend data suggests that stormwater retrofits, septic-to-sewer projects, and land acquisition projects are likely responsible for the majority of the FC declines.
