Lake Darling won’t be filling up this summer as initially planned. A news release from the Iowa Department of Natural Resources indicated the state agency had planned to suspend construction, and allow the basin to fill through labor day. However, The Cedar Rapids Gazzette reports that the DNR will keep the gate outlet open and allow runoff to exit the lake. The DNR State Parks Bureau Chief tells the newspaper they decided the best course would be to stay with the original construction plan.
