Washington ? Sixty years ago, the late Atlanta Mayor William Hartsfield resisted helping to pay for Lake Lanier, a new federal reservoir being built north of town. Atlanta had plenty of water, he wrote Congress. Thanks, but no thanks.

Those words came back to haunt Atlanta last year. A federal judge ruled that the city has been illegally tapping Lanier for years as its primary water source. Unless Congress reclassifies the lake as a water supply, Atlanta will be cut off by 2012.

The question now is how many other cities might be in the same boat. The U.S. Army Corps of Engineers, which sells water from 135 federal reservoirs around the country, recently gave Congress a preliminary list of 40 projects in 14 states that were not initially authorized for supplying water but are being used for that purpose.

Georgia leaders are trying to rally other states as allies in pursuing new classification from Congress for all the Army Corps’ lakes. But many city leaders have a hard time envisioning water shortages — just as Hartsfield did in 1948.

“I think the people around here would come unglued if the government came in and said we don’t have an authorization to use Lake Winnebago after we’ve been using it for close to 40 years,” said Mayor Tim Hanna of Appleton, Wis.

At least 500,000 people in various eastern Wisconsin communities rely on Winnebago for water, even though the corps has said that is not authorized. In southern Kentucky, tens of thousands of people rely on water from Laurel River Lake.

The Atlanta case, brought by Florida and Alabama in a 20-year feud over river rights, highlights a long struggle to reconcile the original intent of the reservoirs with modern demands for water. With water supply traditionally a local responsibility, the federal lakes were mostly built after World War II to generate hydropower or ease river navigation, with private companies paying much of the construction costs.

Only after rapid population growth has the corps increasingly turned to water supply. The shift has often come on shaky legal ground, as U.S. District Court Judge Paul Magnuson found with Lake Lanier.

In his ruling, Magnuson noted that Congress listed water supply as an “incidental” use of the lake, thanks largely to resistance from Hartsfield and other Atlanta leaders. As a result, he found, the corps has been breaking the law by selling nearly a quarter of the lake’s capacity to Atlanta.

Lanier now serves about 3 million people, but Magnuson said the spigot will be mostly cut off in three years if Georgia can’t push a settlement through Congress — a daunting task given fierce resistance from Florida and Alabama, who rely on strong river flows downstream for their own industries.
