A dock on Long Lake surrounded by weeds comes up short on deeper water in August in Coloma. The lake has seen its water levels plummet and has become a marsh. The eight counties that make up the 1.75 million acres of the Central Sands region of Wisconsin host a large concentration of high capacity wells used for irrigation. Scientists are concerned these wells are affecting the levels of lakes and streams.(Photo: Mark Hoffman / Milwaukee Journal Sentinel)Buy Photo

A  Dane County judge ruled on Wednesday that the Department of Natural Resources must take into account the cumulative impacts of high-capacity wells on other water resources when she invalidated seven permits approved by the agency last year.

In a closely watched case, the judge said the DNR had ample authority to set limits on well applications to protect drinking water supplies and lakes and streams that might be imperiled by heavy water use.
