The recent heat wave may have killed thousands of fish, many of which were found dead on Geneva Lake near Albert Lea, Minn., on Monday.

The Albert Lea Tribune reported that Northern Pike, mostly two to three years old, were found belly-up and lining the lake shore. The cool-water fish has problems adapting to excessive heat, according to Minnesota DNR representatives.

Lake temperatures in the area approached 90 degrees last holiday weekend.

The DNR says it likely wasn't a complete kill, as younger Northern Pike have a better shot at surviving the warm temperatures.

More than 200 fish were found dead on Fountain Lake, and dead fish are also being reported on Bear Lake.

The shallower lakes are more susceptible to fish kills, as they heat up much faster than deeper bodies of water.

The Shell Rock River Watershed District along with the city of Albert Lea aimed for funding to dredge Fountain Lake in the last legislative session, but did not succeed.

People had been catching Northern Pike that measured 40 inches or more in the area, which had been almost unheard of before this season, according officials.
