Background

The Greens Bayou watershed covers 208 square miles of densely developed area in Harris County. Much of the watershed area is made up of disadvantaged and underserved communities—with over 60% of the population of low to moderate income. Greens Bayou and its tributaries face water quality challenges including elevated fecal bacteria impairments, and dissolved oxygen and nutrient concerns.

There have been various projects and coordination efforts to address water quality issues on the bayou. The Bacteria Implementation Group (BIG) is one such project. The group covers a broad Houston area of which the Greens Bayou is a sub-segment. They are developing a total maximum daily load to reduce bacteria.
