Cedar Rapids, Iowa News, Sports, and Weather
IOWA CITY - Army Corps of Engineers staff conveyed positive news to Iowa City staff Sunday morning, June 15, reporting that it appears the Coralville Reservoir crested last evening (Saturday, June 14) at 717.0 . Currently, the pool elevation is 716.94, almost 5 feet over the spillway. The earlier projection was for a peak of 717.75 sometime late on Monday. Current outflow from the Reservoir is 39,000 cubic feet per second (cfs); lower than the 42,500 cfs originally predicted at its peak. The Iowa River is now projected to crest at 31.5 feet, lower than the expected 33 feet crest. Local rains and water from local creeks can affect this projected crest and additional rains are expected today.
Keep in mind, however, this flood event will be of prolonged duration. Flooding from rivers alone, such as the Cedar River in Cedar Rapids, subsides more quickly than flooding associated with draining of reservoirs. Army Corp officials stated that, if conditions remain dry, outflows will fall gradually over the next week, until it is expected that the outflow will be approximately 35,000 on Friday, June 20. On June 24/25 it is anticipated levels will be under the spillway. Additional rains will changes these projections.
Even with the projected crest of this flood event, keep in mind that this flood is far from over and residents on the periphery of flooded areas should be prepared for evacuation should conditions arise.
Additional notices: City water, wastewater, and power sources are protected at the current level and barring any unforeseen increases in water level, there is a high level of confidence that these vital services will be uninterrupted.
There are no plans currently to close either of the two remaining river bridge crossings in Iowa City, the Benton Street Bridge and the two spans of the Burlington Street Bridge.
Area curfews and all prior advisories against non-essential vehicle travel in the Iowa River corridor area of Iowa City still remain in effect. Streets and roadways in the river corridor area must remain clear for emergency vehicles and public safety operations.
