Mandatory Water Use Restrictions -- New Guidelines Announced for Lawn Irrigation from Catawba-Wateree Lakes September 5, 2007

In order to conserve water in the Catawba-Wateree lakes, Duke Energy continues to reduce hydroelectric generation. In addition, Duke Energy is announcing new guidelines regarding the use of lake pumps, which lake residents often use for lawn irrigation.

"Declining lake levels have slowed slightly due to further reductions in hydro station flow releases and water conserved through broad implementation of mandatory water use restrictions this past week," said Jeff Lineberger, hydro licensing manager. "If you think of the river as a glass of water, it’s still just over half full when normally it would be around three-fourths full. However, we can tell people are conserving, and it’s making a difference."

One way to further reduce water consumption is to reduce lawn irrigation. Lake pumps are used to pull water from lakes to irrigate lawns. According to the North Carolina Department of Environment and Natural Resources, fescue and bluegrass lawns need only one-half inch to one inch of water every three weeks to stay alive.

Duke Energy’s new guidelines for Catawba-Wateree lake pumps are designed to limit the amount of water used for lawn irrigation. Beginning Sept. 12, 2007, the company will begin patrolling Catawba-Wateree lake pump use as part of routine shoreline observations. Residents who use lake pumps should begin following Duke Energy’s guidelines. The guidelines are:

1. Limit lake pump use to Tuesdays and Saturdays between sunset and sunrise. Remember, only one-half inch to one inch of water is needed every three weeks for most lawns to stay alive. The grass will turn brown as it naturally goes dormant, but as long as it springs back when you walk on it, it’s still alive. If any other use of lake pumps is observed, the resident will be asked to cease the activity.

2. If a lake pump is observed being used a second time outside of the approved guidelines, Duke Energy will take action to remove the pumping facilities from the lake boundary. Continued failure to comply with these restrictions can result in the loss of dock access and consideration of other lake use authorizations for up to five years.

Anyone observing misuse of lake pumps can report it to Duke Energy's lake services line at 1-800-443-5193.

In addition to Duke Energy’s guidelines for mandatory use restrictions for lake pumps, lake property owners should continue to follow the mandatory restrictions for other water use in place for their particular community.

"Duke Energy, along with major public water system operators, encourages everyone to continue conserving water, following mandatory use restrictions and sharing the responsibility as stewards of this region’s limited water supply," Lineberger added.

"We need everyone’s help to protect water supplies. By working together, these efforts buy time until more rainfall can arrive."

Duke Energy's Carolinas’ operations include nuclear, coal-fired, natural gas and hydroelectric generation. That diverse fuel mix provides nearly 21,000 megawatts of safe, reliable and competitively priced electricity to more than 2.3 million electric customers in a 24,000-square-mile service area of North Carolina and South Carolina.
