Heat, plants warm White Bear Lake up to 86 degrees

WHITE BEAR LAKE, Minn. (AP) — The water of White Bear Lake seems to be heating up, a development that might not kill fish but could still present challenges for anglers.

WHITE BEAR LAKE, Minn. (AP) — The water of White Bear Lake seems to be heating up, a development that might not kill fish but could still present challenges for anglers.

A reading this month registered 86 degrees. That's 2 degrees warmer than the same date last year, and 12 degrees higher than last month.

State wildlife officials say the spike is partly due to the recent heat wave, but also to an invasive plant species.

Chip Welling is with the state Department of Natural Resources. He says there's been rapid growth of watermilfoil, a tangled mat of vegetation that prevents warmer water from blending with cooler water.

The warmer temperatures aren't expected to kill fish, but it may drive them to deeper, cooler water. A Minneapolis Star Tribune report says that could frustrate anglers.
