August is Water Quality Month, and we are sharing information from the Water Security issue of txH2O, How does water quality monitoring work?, an explainer on the process of watershed restoration.
The Navasota River is a predominantly rural watershed with portions of the river below Lake Limestone and several of its tributaries listed as impaired on the Texas Water Quality Inventory and 303(D) List due to high levels of E. coli. These bacteria come from the many animal and human sources across the watershed. Their presence in surface water above state water quality standards indicates an increased risk to human health for those choosing to contact recreate (swimming, diving, children wading, etc.) in these waters.
In an effort to reduce E. coli levels in the river, TWRI is working with watershed stakeholders to address water quality concerns and improve watershed health and function. A planning process was completed that yielded a scientifically supported plan to restore water quality through voluntary management of E. coli at its source across the watershed. A watershed protection plan, a total maximum daily load and an implementation plan were all developed for the watershed. These plans are built upon stakeholder feedback and addresses human sources (septic systems and wastewater infrastructure) and animal sources (feral hogs, livestock, and pets) through physical management and increased education and outreach.
