Fight over groundwater pumping follows White Bear Lake ruling

An unprecedented order last year to throttle water use in the northeast metro area pitted the freedom to water lawns against the size of White Bear Lake.

The lawns appear to be winning — for now.

Eleven cities are fighting court-imposed residential irrigation bans intended to boost the levels of White Bear Lake, which a judge concluded was receding because nearby wells sucked up too much groundwater. The Legislature moved this week to pause irrigation bans and other court-ordered changes, which cities say are unfair and ineffective.

"If you wanted to do a good job managing the resource, you would never do these things," said Bryan Bear, the city administrator of Hugo. "Not only are they impactful and expensive to deal with and inconvenient … but they're also counterproductive."

The problem might not exist if cities pulled their water from the Mississippi River, as Minneapolis and St. Paul do, rather than tapping aquifers deep underground. But the Legislature hasn't been willing to pay for such a regional system, which the Metropolitan Council estimates could cost between $150 million and $620 million depending on how many cities are connected.

Spring was blooming around the lake one recent morning, as blackbirds perched on reeds, turtles surfaced and fisheries staff checked their nets for muskies. A casual observer would be hard-pressed to spot a problem with the lake.

Last year's controversial ruling by Judge Margaret Marrinan stemmed from a 2013 lawsuit filed by White Bear Lake homeowners and other lake advocates against the state Department of Natural Resources (DNR). When the fracas began, the lake was hovering at historically low levels and its shoreline was drying up. It has since rebounded, which U.S. Geological Survey (USGS) experts say is due to unusually high recent rainfall.

Markoe wishes cities were responding more proactively to the judge's ruling. He noted that if current trends continue, the Met Council has projected declines in some parts of the Prairie du Chien aquifer by 2030. That aquifer supplies water for 83 communities in the Twin Cities.

"We're 12 years away from a crisis, and White Bear Lake is telling us that the crisis is coming," Markoe said.

The judge's order required permitted water users within 5 miles of White Bear Lake's shoreline to impose residential irrigation bans if the lake's level fell below a certain point. It also required them to limit per capita water use and plan for a conversion to surface water in the future.

That applied to permits held by White Bear Lake, Lake Elmo, Lino Lakes, Vadnais Heights, North St. Paul, Hugo, Stillwater, Oakdale, Mahtomedi, St. Paul and White Bear Township. It also covered a number of private wells used for golf course irrigation, agricultural irrigation and food processing, among other things.

Nearly a quarter of the water used by Twin Cities residents goes outdoors, largely for irrigation, according to the Met Council. But the DNR, which is appealing the ruling, believes a residential irrigation ban would only affect lake levels by only a few inches each year.

Ironically, one of the cities fighting the irrigation ban is St. Paul, whose 400,000 customers got roped into the regulations because the city maintains a number of emergency wells within the 5-mile radius of White Bear Lake.

"To be included in the group of water suppliers being subject to a watering ban when we are 100 percent surface water, it just doesn't make sense," said Steve Schneider, general manager of St. Paul Regional Water Services. "It's not going to impact the level of White Bear Lake."

Other cities, such as White Bear Lake, say it is unfair to put that burden solely on residents and not on commercial or public properties.

"You would find commercial properties and public properties being irrigated — or having the opportunity to irrigate at least — and residents not. And therein lies some conflict," said White Bear Lake City Manager Ellen Richter.

It's also difficult to enforce.

Bear added that limitations on per capita use would encourage cities to build apartment buildings, which consume more water but use less per person.

The cities have challenged the restrictions, putting the new requirements on hold. The bill that passed the Legislature and awaits Gov. Mark Dayton's signature would pause enforcement for a year.

Lake levels also dropped from the late 1980s into the early 1990s, but USGS hydrologist Perry Jones said that was during a major drought. Since then, development has sprawled into the area, and groundwater pumping has accelerated.

Jones said the drop in lake levels between 2003 and 2010 was similar, but there was no drought. "So there was a different factor that we felt was causing that drop," he said.

Unusually high rainfall in recent years has refilled the lake and seeped into the aquifer. But if rain returns to normal, he said, the effects of groundwater pumping may cause the lake to recede once more.
