ATLANTA - Georgia lawmakers met this week to discuss how to increase the state's water supply.

Georgia is locked in a tri-state legal battle over water that has environmental and economic implications for the region. Sen. Ross Tolleson of Perry says a combination of reservoir development, conservation and alternative methods are needed to achieve an adequate supply of water.

Tolleson also says the tough economic climate will hamper Georgia's ability to pay for water infrastructure projects.

While reauthorizing the use of Lake Lanier as a main water supply is a priority, those who spoke at this weeks' meeting of the Joint Committee on Water Supply say a substantial investment in water infrastructure is needed.

Co-chairs Tolleson and Rep. Lynn Smith of Newnan plan to petition to have the committee reconstituted for a year to allow for more critical study of the issue.
