The Army Corps of Engineers at Saylorville Lake have their work cut out with all this rainwater.
The inflow rate is increasing while the outflow is not.
The inflow was at 26,400 cubic feet of water per second Wednesday and the outflow was just 10,000 cubic feet of water per second.
The latest stage of the reservoir was just over 845 feet above sea level, that’s an increase of about five feet in the past 24 hours.
It’s expected to keep rising a further 25 feet to nearly 870 feet by June 5th.
Saylorville is just north of Des Moines and was built to provide flood protection for the city.
