Bridging-the-Headgate in Texas
Sub Surface Drip Irrigation Demonstration Field Day - Tom Green WCID#1
2004 was the first year of a cooperative 3 year demonstration program to show that sub-surface drip irrigation (SDI) technology is feasible utilizing treated effluent as a source of water. Partners in the effort include Reclamation, Tom Green County Water Control and Improvement District #1, Natural Resources Conservation Service, Tom Green County Soiland Water Conservation Board, Texas State Soil and Water Conservation Board, Texas Cooperative Extension Service. Local irrigators h
ave been slow to adopt micro-irrigation technology in the water district due to concerns about system plugging when using treated wastewater. This project demonstrates design, operation & maintenance, and proper management of a state of the art, high efficiency, subsurface drip irrigation system. The design incorporates water supply chemical treatment and filtration. This demonstration will help to encourage local farmers to adopt water more efficient irrigation technologies which save water and further stretch short water supplies in a competitive area. To help highlight the demonstration on June 20, 2004, the partners hosted a field day for approximately 50 local farmers.
Lower Rio Grande Valley
In December 1999, Reclamation staff toured the Lower Rio Grande Valley in southern Texas with State Conservationist John Burt and other NRCS staff to learn more about proposed legislation for a comprehensive irrigation improvement program that could involve both on-farm and off-farm measures. During the visit, the group met with the Rio Grande Valley Irrigation District Managers Association, and attended a joint meeting of the Southmost, Hidalgo, and Willacy Soil & Water Conservation Districts to discuss the proposed legislation and some of the local conservation issues, water management practices, and water supply infrastructural needs.
Erosion Control at Twin Buttes
In 1999 Reclamation and NRCS signed a joint agreement to work cooperatively with the NRCS in Texas, and the City of San Angelo, on an analysis of methods to control erosion on the face of Twin Buttes Dam. The study was conducted to evaluate alternatives to control erosion and stabilize the steep-sloped earthen face of the dam. NRCS provided expertise in soil bio-engineering, erosion stabilization, and plant material adaptation.
On-Farm Irrigation Management Support
In 2000 the Oklahoma-Texas Area Office purchased three portable transit-time flowmeters for use by the NRCS to support irrigation water management activities in Oklahoma and Texas. Reclamation The flow meters were provided to NRCS field offices in Lubbock, Texas; Altus Oklahoma; and Anadarko, Oklahoma.
Reclamation Sponsored Training
As part of the "Bridging-the-Headgate" coordination offered through Reclamation OTAO tuition for two NRCS irrigation engineers were sponsored to attend the January 2000 flow measurement training course in Denver, Colorado.
