Onsite Comments

On January 23, the city of Cedar Rapids reported an estimated release of 450,000 gallons of chlorinated drinking water from an unoccupied building located at 4425 Center Point Road NE, which eventually entered McLoud Run. City officials believe the release was caused by a fire suppression line that may have burst during the recent cold snap, but were unaware of any pressure loss.

DNR staff from the Fisheries Bureau are investigating the fish kill, but have been hampered by very murky stream conditions. Staff have observed between 200-300 dead fish as of this morning, including trout and white suckers.

McLoud Run is Iowa’s most southerly trout stream and the only trout stream near a major urban area. Several popular fish species in this stream include Brown Trout, Creek Chub, Rainbow Trout, Green Sunfish and White Sucker.
