The Center for Lakes and Streams has tested Winona Lake again for chemical concentrations after the February Warsaw Chemical explosion released 325,000 gallons of fire flow water into the lake. According to the organization, they have found no signs of wildlife impact due to the spill. Chemicals that initially entered the lake at high concentrations were diluted down within one week following the spill to concentrations well below human health guidelines. During the last weekend of April, another spill was reported in the same area of Winona Lake, originating from Dalton Foundry. Booms were placed in the lake near the spill site to contain the oil. The City of Warsaw Stormwater Utility and IDEM are working with Dalton Foundry to address this incident.
