Undated (KICD)–Heavy rainfall has overwhelmed some drinking water, sewer treatment plants and animal feeding operations from Lyon to Linn County.
In Clay County, the Iowa Lakes Regional Water had one stream crossing washed out. A small portion of the system is without water and those customers will be under a boil advisory after service is restored.
In Wahpeton, the water plant has lost power, but the city is buying water from Milford, enabling the system to meet demand and maintain pressure.
The drinking water plant in Rock Rapids was shut down after the clear well was inundated with water. Lyon and Sioux Rural Water have had stream crossings wash out and are rerouting water to try to maintain pressure. Rock Rapids and the Rock Rapids subsystem of Lyon and Sioux Rural Water have issued boil warnings as the rural water system buys part of its water from Rock Rapids. The Rock River near Rock Rapids was 26 feet high at noon Tuesday, up from less than 10 feet on June 14th. The flood stage is 13 feet.
In Rock Valley the city lost power to three of the four wells, but was still operating on the one remaining well.
Flooding on the Big Sioux and Rock rivers is expected to reach historically high levels. People should avoid recreation in flooded streams and rivers.
In Hawarden the city was sandbagging to protect two wells, but is able to meet demand with remaining wells.
The DNR has received reports of 34 cities, most in northwest Iowa, that have discharged wastewater because of the rainfall.
