Navasota River: A Community Project to Protect Recreational Uses

A project to reduce bacteria and protect recreational safety in the Navasota River. The community has developed an Implementation Plan (I-Plan), which together with total maximum daily loads (TMDLs) developed by the TCEQ with community feedback, provide the the road map for improving water quality. The commission has adopted the TMDLs and approved the I-Plan.

Background and Goals

The Navasota River, Segment 1209, begins below Lake Limestone and flows until it connects with the Brazos River southwest of the town of Navasota. It is a predominately rural watershed in the larger Brazos River Basin. Bryan and College Station are the largest urban areas.

High concentrations of bacteria, which are found in both human and animal waste, have been observed in the river. The presence of these bacteria may indicate a health risk to people who swim or wade in the bayou—activities referred to as “contact recreation” in the Texas Surface Water Quality Standards.

The goal of this project is to improve water quality in order to protect recreational uses. Toward that goal, the TCEQ is developing a TMDL and an I-Plan to reduce bacteria in the Navasota River.
