It began four years ago as a lawsuit over water levels in White Bear Lake, a recreational jewel of the Twin Cities suburbs. But the ruling that emerged in a Ramsey County courtroom this month could have sweeping implications for water use across all of Minnesota, forcing the state to impose limits on everything from suburban sprawl to crop irrigation.
In a sharp rebuke to the Minnesota Department of Natural Resources, Judge Margaret Marrinan said the state has failed to protect White Bear Lake from excessive groundwater pumping and ordered the agency to limit water use in the surrounding communities. The state, she ruled, has a broad duty to protect the lake and the groundwater as a public trust — in essence recognizing that despite being one of the most water-rich states in the nation, Minnesota doesn't have an endless supply.
Conservationists and environmental lawyers say the ruling, if it stands, has implications for sectors as diverse as manufacturing, agriculture, mining and drinking water across the state.
"This is new," said Alexandra Klass, who teaches environmental law at the University of Minnesota. "We are used to having as much water as we want."
And while environmentalists see it as a critical victory for the lakes, rare fens, wetlands and rivers that the state is obligated to protect, the decision will intensify what are already fractious political fights over Minnesota's water.
"The whole issue of water policy is in play," said Sen. Chuck Wiger, co-chair of the Minnesota Legislative Commission on Water, whose district includes White Bear Lake. It's possible, he said, that the Legislature will try to weaken or rewrite the strong environmental laws that underpin Marrinan's ruling.
"I imagine we are going to see some pre-emptive strikes," he said.
DNR officials haven't said whether they plan to appeal the decision, but in a statement last week, they sharply disagreed with the judge's findings.
