Local authorities, environmental groups and the University continue to pursue water conservation policies even after heavy local rainfall in March.

With lakes Travis and Buchanan still less than half full, Central Texas remains in a drought, said Clara Tuma of the Lower Colorado River Authority, which provides wholesale water to the City of Austin. Austin is still under the enhanced stage two water use restrictions set by LCRA, she said.

“Enhanced stage two allows landscape watering no more than once a week,” Tuma said. “Enhanced stage two occurs when the combined storage of lakes Travis and Buchanan falls to 750,000 acre-feet or less.”

The recent rainfall raised water levels in those lakes, but it did not fall far enough west in the crucial aquifer recharge zone, said Tyson Broad of the Sierra Club.

“It appears that the rain fell in the low parts of the [Colorado River] basin, not in the major recharge area of porous limestone that helps the lakes stay up,” he said.

It is unlikely that Austin will return to the less severe stage one restriction, said Michael Frisch, the University’s senior building energy and water conservation project manager.

“It’s more likely that we will move to stage three,” he said. “There probably won’t be enough rain to warrant a move in the other direction.”

The stage three restriction, as it is currently defined by the LCRA, is not designed to address a long-term water shortage, said Jason Hill, spokesman for Austin Water.

“The stage three restriction code is intended to respond to a catastrophic event,” he said. “If stage two is not enough, the groups involved are looking to make changes to the code.”

Hill said the diminished water supply results from events in nature, not the mismanagement of resources. He said Austinites should be proud of the extent to which they have conserved water since the onset of the present-day drought.

“Stage two restrictions have been very effective in decreasing water consumption, and we applaud our customers,” he said. “If we haven’t done the best job [in implementing water conservation among other Texas cities], we’ve certainly been very competitive.”

Frisch said the University has been doing its part to reduce water use. He said a new irrigation system installed in response to the drought conserves water and reduces the University’s water bill.

“The new system measures how much water is evaporating from plants and knows how much rainfall there has been,” he said. “It also detects leaks and sends a signal to the main control system. We then deploy an irrigation technician to check out the problem.”

The improved watering system saves the University from consuming 50 million gallons of water each year because it prevents leaks and unnecessary irrigation, Frisch said. With the University paying $11 per 1000 gallons, according to Frisch, conserving that much water saves the University a significant amount of money.

Farmers, businesses, environmentalists vie for precious resource amid one of the worst statewide droughts in history

Rice farmer Ronald Gertson uses millions of gallons of water each year to maintain his crop in southeast Texas. A full Lake Travis is the lifeblood of marina owner Janet Caylor. The Sierra Club’s Jennifer Walker monitors water conditions throughout the lower Colorado River to ensure plants and animals continue to thrive.

As drought conditions worsen across Texas, these and other stakeholders who rely on the river’s reservoirs compete to ensure the Lower Colorado River Authority protects their interests. For the first time in more than 10 years, droughts are affecting every part of Texas, according to the U.S. Drought Monitor. Lack of rain combined with warm, windy weather have led to one of the worst droughts in history, causing wildfires across the state, said LCRA meteorologist Bob Rosec.

Last summer, the LCRA created the Water Management Advisory Committee to gather input from groups that depend on Lakes Travis and Buchanan to update the Water Management Plan, which determines allocation of the increasingly limited water resources. The two lakes are dammed sections of the Lower Colorado River that serve as the water supply reservoirs for the 600-mile section of the river the authority oversees.

It’s difficult to meet the demands of farmers, environmentalists, waterfront homeowners, business owners and others as the need for water increases with a growing population, said Mark Jordan, manager for River Management for the LCRA.

“Drought and the resulting potential curtailments cause a lot of emotions to fly,” said Gertson, a fourth-generation rice producer and committee member.

Gertson planted his crop last month, the driest March on record, according to the LCRA. Water keeps the soil saturated and prevents weeds and grasses from competing with the rice crop. During drought, Gertson and other farmers must take additional measures to ensure successful harvests.

“When we’re dry [during the] early season like this, we have to use more water in establishing the crop than we would otherwise,” Gertson said.

Rice farmers use more water from the reservoirs and pay less to access it compared to any other type of major customer, including cities or waterfront businesses, but the LCRA considers farmers interruptible customers, so their water can be cut off during drought. The authority guarantees cities, businesses and industries will keep their water even if droughts reach record levels.

The LCRA has not curtailed the farmers’ water supply, but Gertson remains cautious. With the rice industry in Texas smaller than it was decades ago, the growing demand of cities on the water supply could edge out the rice farmers, Gertson said.

Gertson’s great-grandfather moved to Texas from Kansas in 1908 and discovered a few years later that rice was a lucrative crop. Today, Gertson runs the business with his three brothers, their wives and his father. Gertson’s son Timothy, an engineer, has joined the family business against his father’s wishes.

“During Tim’s lifetime, there will be lots of times there won’t be crops planted as a result of a lack of water,” Gertson said.

Lakeside, waterfront property and business owners see rice farmers as culprits responsible for visibly low lake levels. When the authority maintained the downstream water supply to the rice farmers during the previous drought, waterfront business owners and homeowners felt an impact on their pocketbooks because of emptying reservoirs. The Highland Lakes area, which includes lakes Travis and Buchanan, is an economic engine for the state, said Janet Caylor, who is a member of the committee and owns a marina on Lake Travis.

“When the lake goes down, visits to the lake drop dramatically,” Caylor said, who bought her first marina 13 years ago.

During the previous two-year drought, business owners had to relocate all floating restaurants and marinas, and lake-area property values declined, Caylor said. Two marinas and a restaurant went out of business when droughts caused combined storage levels in Lakes Travis and Buchanan to fall below 800,000 acre-feet in 2009, she added. An acre-foot is a measurement that describes the volume of a foot of water on top of an acre.

Waterfront business owners and homeowners want to increase the minimum amount of water stored for the two lakes so the reservoirs will serve their needs. Under the current water management plan, the storage level is permitted to fall as low as 200,000 acre-feet.

“The fact that the other interest groups can engage in the conversation where they think the volume in these two lakes should be drawn to the 200,000 acre-feet level is astonishing to us,” Caylor said.

Recently, residents and business owners with an interest in lake water levels formed a coalition to acquire more political clout and urge the authority to prioritize their economic interests in the new plan, she said.

“This is about preserving revenue for the state of Texas and preserving the livelihood for these hundreds of thousands of people who moved to the [lake] area,” Caylor said.

Jennifer Walker, a water resources specialist for the Lone Star Chapter of the Sierra Club, said wildlife that live in the river are at risk. From an environmental perspective, drought is a normal, cyclical phenomenon. Walker, also a committee member, said environmentalists want to avoid above-normal drought conditions in the Colorado River and the Matagorda Bay downstream.

Walker said that the river and bay provide ecological services to support wildlife. Stakeholders and the LCRA must consider how the water maintains a level and saltwater gradient that supports wildlife in the river and bay, she said.

The committee has until the end of June to agree on a possible course of action, but with each player deeply invested in the river’s future management, it’s an emotional and difficult process. The authority won’t vote on a final Water Management Plan until November 2012. It will then go to the Texas Commission on Environmental Quality, which will go through its own planning process before implementing changes.
