big eau pleine reservoir

Last year was the wettest year on record in the Wisconsin River basin.

That meant reservoirs were full, and challenging spring weather could put stress on the system.

But the forecasts are looking better than anticipated.

The Wisconsin Valley Improvement Company manages flows on the Wisconsin River and operates five dams on major reservoirs.

The company had to aggressively draw down water levels over the winter after last year’s record precipitation.

But company vice president of operations Peter Hansen said the spring, so far, has been manageable.

On Tuesday, Scott Blado found good news as he dipped scientific instruments below the ice on the Big Eau Pleine Reservoir in Marathon County. 

“Right now, we’re seeing [a reading of] 10.9 dissolved oxygen, which is fantastic.  We couldn’t ask for anything better than that at this time of the year,” said Blado, an environmental specialist for the Wausau-based Wisconsin Valley Improvement Company (WVIC).

Blado tests multiple points on the reservoir every week, and on Tuesday, he saw a significant jump from the week before.
