Prevent Winter Fish Kills on Iowa Ponds
This article was published originally on 11/22/2013
Winter fish kills and oxygen depletion on ponds are particularly common in Iowa, especially on ponds with high nutrient loads, heavy aquatic vegetation prior to freezing over, and those with small surface area and shallow water depths. See the Iowa State University Extension & Outreach news release for November 20, 2013 for more information on preventing winter fish kill in your pond.
