Commercial manure applicator company Precision Pumping was land applying manure with an umbilical rig. There was a booster pump set up on the bank of the creek and the charged supply side hose came off the pump and flopped into the creek, pumping what an applicator representative estimated to be 10K gallons of manure directly into the creek before he could get the supply line shut down. There is currently a large number of dead and dying fish in the creek and the slug continues to move downstream. Lotts Creek is approximately 10-feet wide and 1-2 feet deep and has a high velocity flow, but there is little in the way of dilution due to a lack of significant tributaries and the fact that field drainage tiles in the area are not currently discharging; this kill is expected to be ongoing. The regional DNR fisheries biologist has been notified and fisheries staff will be on-site tomorrow morning to begin a fish count.
Day 2:FO2 staff were on scene most of the day today and documented that the manure slug had dissipated and the fishkill terminated at a point approximately 10-miles downstream of the spill site. Field testing and observations today revealed that the affected portion of Lotts Creek has returned to background levels with regard to water chemistry (e.g., Dissolved Oxygen, Ammonia, etc.) and live fish were observed. There was no obvious evidence of an impact (i.e., dead fish, colored water, odor, etc.) to the East Fork Des Moines River. DNR Fisheries staff conducted a dead fish count today as well; their report, and the results of laboratory analysis of water samples will be forthcoming in the near future.
