Keep the San Saba River Flowing!

Ask State Sen. Fraser to Co-sponsor Texas House Bill 2546 and the TX Committee on Enviro. Quality to correct water waste and abuse and enforce the existing law.

The San Saba River is a scenic waterway located on the northern boundary of the Edwards Plateau in Texas. Flows of sparkling, clear water course through limestone bluffs and hills, supporting fish, wildlife, and recreation. Through wasteful water use and unregulated pumping, irrigators are transforming a vibrant, pristine river into a dried-up riverbed.

The Texas Commission on Environmental Quality must enforce the law to ensure adequate flows are maintained. Further, the Texas Legislature should appoint a watermaster on the upper stretch of the San Saba River to better manage flows and protect the river long-term.

The Threat

Texas law provides that all natural surface water found in rivers is owned by the state and is held in trust for its citizens.  There are no sealed meters and no accurate methods for the state to know whether irrigators around Menard, Texas, are exceeding their allowed limits.

Excessive pumping for agricultural irrigation has been diverting the river’s flow into a canal (where 30 percent or more is lost due to evaporation and leaks).  Moreover, some irrigators place extremely shallow wells next to the river to pull water from the river under the guise of groundwater wells.  This unregulated pumping in the last twelve years has almost dried up over 50 miles of the river for an average of five months of the year.  This hurts downstream ranchers who need water, damages the river ecosystem, and negatively impacts the Austin chain of lakes.

While pumping is certainly legal by permitted landowners, such permit holders are required to leave a flow in the river sufficient to service the domestic and livestock users downstream.  In 2011, after priority calls were made by ranchers, the Texas Commission on Environmental Quality (TCEQ) did the right thing and suspended pumping.  The river filled up and flowed again despite irrigators’ claims that it was drought– not excessive pumping– that had dried up the river.  When irrigators pumped the river dry again in 2012, the TCEQ inexplicably denied the priority calls from downstream ranchers, refusing to enforce the law because they claimed they did not feel the suspension would result in restored river flows.  This position was puzzling since the flow returned to the river after the suspension in 2011– the year of the worst drought in more than 60 years.

What Must Be Done

Enhanced enforcement of the existing law is needed to ensure the river continues to flow.  Ultimately, the appointment of a watermaster on the upper stretch of the San Saba River is necessary to monitor stream flows, reservoir levels, and water use, and to prevent the wasting of water and its use in quantities beyond a user’s right.  In the past, Texas has successfully implemented such a system on other rivers whereby the watermaster regulates the pumping so that the river maintains a stable flow.  The legislature should appoint a watermaster for the river’s upper stretch to maintain the health of the river for its many users, the Highland Lakes and the coastal Bays.

The TCEQ is the state agency responsible for protecting the state’s rivers.  However, with no meters to regulate how much water is actually being pumped, and given the State’s ineffective and underfunded enforcement program, the San Saba River has no protection.  Based on TCEQ records obtained through the Public Information Act, there has been illegal pumping and management irregularities in this basin.  The agency must act to enforce the law and stop waste and abuse.

To do this, TCEQ should require sealed meters to monitor pumping activity, eliminate shallow water wells, and suspend pumping when flow is threatened.
