Continued Statewide Delivery of the Texas Watershed Steward Program

Project Background:All watersheds in Texas are threatened by nonpoint sources (NPS) of pollution which are detrimental to the valuable water resources of the state. To help combat this threat, federal and state water resource management agencies have adopted a watershed-scale approach for managing water quality. One vital component of this approach involoves engaging local stakeholders to become actively involved in planning and implementing water resources managment and protection programs in their watershed.

Implementing the Arroyo Colorado WPP by Providing Technical and Financial Assistance to Reduce Agricultural NPS

Project Background: The Arroyo Colorado (Segment 2201 and 2202), an ancient distributary channel of the Rio Grande, extends about 90 miles from Mission, Texas to the Laguna Madre in the Lower Rio Grande Valley. Flow in the Arroyo Colorado is sustained by wastewater discharges, agricultural irrigation return flows, urban runoff, and base flows from shallow groundwater. Elevated levels of bacteria and low dissolved oxygen have severely impacted recreational use of the lower Arroyo Colorado for fishing and swimming.
