GREEN BAY, WI (WTAQ) – The so-called “dead zone” in the Bay of Green Bay did not last as long as expected this year.
The Green Bay Metropolitan Sewerage District says there were 3 days with extremely low oxygen levels in the southern part of the bay in 2015. That was 2 days longer than a year ago.
But in 2013, there were 15 days where oxygen levels fell to less than 2-milligrams per liter. And there were 33 days of low oxygen in 2011.
J-Val Klump of the Great Lakes Water Institute at UW-Milwaukee says scientists thought it would a terrible year for oxygen deprived water.
That’s because conditions were favorable for large farm runoffs, spurred in part by a large amount of late fall manure spreading.
