Continued Implementation of the Geronimo and Alligator Creeks Watershed Protection Plan


In 2007, the TSSWCB Regional Watershed Coordination Steering Committee, using established criteria, ranked Geronimo Creek in the top 3 watersheds for selection of WPP development. The development of the WPP for Geronimo and Alligator Creeks has been a stakeholder driven process lead by Extension with support from the GBRA. The Geronimo and Alligator Creeks Watershed Partnership (the Partnership) Steering Committee includes local officials, land and business owners and citizens and is supported by state and federal agency partners. With technical assistance from project staff, the Steering Committee has identified issues that are of particular importance to the surrounding communities, and has contributed information on land uses and activities that has been helpful in identifying the sources of nutrient and bacterial impairments, and in guiding the development of the WPP.

Nonpoint source pollution is considered a significant contributor to water quality issues in Plum Creek. Based on information gathered in the watershed and through discussions with local stakeholders, key potential pollutant contributors were determined to be urban runoff, wastewater, agriculture. Implementation of the WPP is underway to coordinate the implementation, implement agricultural components of the WPP, and to monitor Surface Water Quality in the Watershed.

Coordinating Implementation

Extension will facilitate the Geronimo and Alligator Creek watershed Partnership through coordination with all key stakeholder groups and partner agencies to implement management measures for all three key categories of nonpoint source pollution: urban, wastewater and agriculture.

Extension will facilitate and coordinate outreach and education activities in the watershed.

Implementing Agricultural Nonpoint Source Components of the WPP

This project will provide agricultural producers in the Geronimo and Alligator Creeks watershed with an opportunity to participate in water quality educational activities and receive technical and financial assistance for the development of Water Quality Management Plans (WQMPs) and implementation of best management practices (BMPs).This project provides funding to support implementation of recommended agricultural management measures identified for action in the WPP during the first 3 years of the 10- year implementation schedule. To achieve this goal, the Comal-Guadalupe SWCD #306 willhire one District Technician who will provide technical assistance to agricultural producers in developing and implementing WQMPs and Prescribed Grazing Plans in the Geronimo and Alligator Creeks Watershed.

Surface Water Quality Monitoring in the Geronimo and Alligator Creeks Watershed

Guadalupe Blanco River Authority currently conducts Surface Water Quality Montoring in the watershed to look for data trends and fill data gaps. Maintaining an effective monitoring program will provide critical water quality data that will be used to judge the effectiveness of WPP implementation efforts and serve as a tool to quantitatively measure water quality restoration.
