Troubled Waters

Although state ecologists have blamed recent fish kills near Stuart on microalgae that thrive on nutrient-rich water from Lake Okeechobee, they have not stopped the flow of lake water.

Instead, federal, state and local agencies regulate the flow levels while monitoring the water quality and health of the estuary.

With an extremely wet winter, water in the lake has reached a historic high, even wicking through the levee in some places, said Paul Millar, director of the South Florida Water Management District's Stuart office.

The Army Corps of Engineers, which regulates the lake, needs to relieve stress on the levee by releasing water. But it cannot send water south because of U.S. Fish and Wildlife regulations to protect the Cape Sable seaside sparrow, an endangered species that nests there.

The water has to come out along the St. Lucie Canal on the east and the Caloosahatchee Canal on the west. Fresh water heading toward the Indian River Lagoon flows through the St. Lucie Canal, picking up nutrients and sediments from urban and agricultural areas before pouring into the St. Lucie River and Indian River Lagoon.

In the river and lagoon, the microalgae bloom in the nutrient-rich fresh water, according to the state Department of Environmental Protection. The tiny organisms eat the mucus off fish such as the silver mullet, which then develop lesions and sores.

Army Corps of Engineers:

This federal agency built South Florida's entire drainage system but relinquished control of most of it to the South Florida Water Management District in 1979. Now it controls just Lake Okeechobee and the two canals that flow out of it: the St. Lucie and the Caloosahatchee.

With water levels in Lake Okeechobee more than four feet above normal, federal engineers plan to continue sending water through the St. Lucie Canal and into the local estuary, said Jacquelyn Griffin, spokeswoman at the Corps' Jacksonville headquarters.

South Florida Water Management District:

Created in 1972, the state agency controls 1,400 miles of waterways and canals throughout South Florida and the Everglades. It also maintains 2,000 water-control structures.

Locally, the district maintains every canal but the C-44 or St. Lucie Canal. The district controls the other drainage canals that flow into the St. Lucie River estuary and monitors water quality in them.

Stuart field office: 223-2600.

U.S. Fish and Wildlife Service:

To protect the Cape Sable sparrows, the agency has prevented the Corps of Engineers from releasing Lake Okeechobee water south through the Everglades.

The sparrows, which have declined from 6,450 in 1992 to 2,800 in 1997, nest in subtropical marshes that would be flooded if the lake water was released there, said Skip Snow, a wildlife biologist with the service. Besides the sparrows, the unique marshy habitat has been threatened by Lake Okeechobee runoff, he said.

"The sparrow is the poster child for the marshes," he said. "The sparrow represents the conflict between the growth of urban uses and natural patterns."

FWS won't permit the Corps of Engineers to send water into the Everglades again until the beginning of the rainy season, Snow added.

Department of Environmental Protection:

Biologists from the state agency are investigating causes of the fish kill by studying the fish and testing water samples. Scientists at the agency's Marine Research Institute in St. Petersburg already had started a study of sick fish in the Indian River Lagoon, the St. Johns River and the St. Lucie River.

U.S. Geological Survey Water Resource Division:

This federal agency does not have regulatory control but collects data on water quality and salinity in Florida waters. Often the agency works under contract to the South Florida Water Management District, said Tom Richards, chief of the agency's Stuart field office.

Stuart field office: 286-6299.

Florida Cooperative Extension Service - Institute of Food and Agricultural Sciences at the University of Florida:

With offices in every Florida county, the agency provides educational services but does not have any regulatory controls. It teaches farmers and ranchers how to minimize environmental impact, said Jim Cummings, St. Lucie County extension director.

The agency also issues an annual list of pesticides that farmers can use on their crops and the potential problems those chemicals could have on the environment. For example, the service tells farmers how to use the pesticide Abamectin, while warning the chemical is "toxic to fish, mammals and aquatic organisms."

Martin County field office: 288-5654.

Martin and St. Lucie county commissions:

The counties created a joint task force in 1995 to study places for Water Preserve Areas, manmade marshes that would hold storm runoff and Lake Okeechobee effluence.

After the study, the St. Lucie County Commission supported the idea, allowing federal and state officials to begin building a water preserve in northern St. Lucie County.

Martin County officials have been divided on the issue, stalling efforts to create the preserves there. Donna Melzer, commission chairwoman, said Wednesday that she has changed her mind and will support the water preserves. Her support will be critical because three of the five commissioners had opposed the idea.
