WAPELLO – The U.S. Army Corps of Engineers’ procedures on handling outflow from the Coralville Reservoir near Iowa City could be impacted by the recent high water on the Iowa and Cedar rivers.

Louisa County Emergency Management Services Director Staci Griffin told the Louisa County Board of Supervisors on Tuesday that despite a denial to change any outflows that could have affected the most recent flooding, local, state and national officials were now working to update flood graphs and other data, which could eventually lead to outflow changes.

Last week, Griffin said, she and other local officials would ask the Corps to increase the outflow from the reservoir, which manages water coming down the Iowa River watershed, explaining they felt an increased outflow would not cause any significant additional impact from the flooding.

“We can handle it now,” Griffin had told the supervisors during their Sept. 4 meeting.

However, she had also told the board at that meeting that if additional rain to the north occurred — causing both the Iowa and Cedar rivers to rise and eventually forcing the Corps to increase the outflow from Coralville — the additional flooding could cause significantly more impact.

That had led Griffin and other local officials south of the Coralville Reservoir to petition the Corps to increase the outflow — the request it eventually denied, based on the current flood graphs.

Griffin reported that on Sunday, she and other EMS and National Weather Service personnel flew over flooded areas from Johnson County to Oakville in Louisa County and then doubled back and flew up a portion of the Cedar River corridor.

“We took a lot of pictures — there are probably over a thousand pictures that we collected,” she told the board.

Griffin said the officials would now review the current flood graphs and other data used by the Corps to establish outflows from the reservoir and compare the photographs and other observations to determine if adjustments could be made.

Griffin indicated she would expect some changes.

“While we were in major flood stage, we had no unpredicted impacts, so those flood levels are going to go up and we’re working with (a weather service hydrologist) to see exactly where we want those to lie,” she said.

“We’re trying to get accurate information out,” Griffin continued.

The supervisors said they appreciated hearing of the flood update effort.

In other action, Louisa County Public Health Services Interim Administrator Roxanne Smith told supervisors the Louisa County Board of Health recently approved a draft plan for Rural Utility Service System of Southeast Iowa to assume management of the county’s water testing program.

The management had previously been handled through the health service, but a new procedure became necessary after the board of health recently fired an employee. Smith said the procedures and a memorandum of understanding between the board of health and RUSS still needed to be approved by the RUSS board.

The supervisors also:

• Met with veteran affairs director Adam Caudle for his monthly report;

• Agreed to transfer the tax certificate on a vacant Wapello property to Shawn Maine;

• Met with Mike Norris of the Southeast Iowa Regional Planning Commission for an update on housing programs available through the commission;

• Learned from county engineer Larry Roehl that work on the Louisa County 99 replacement bridge project at Wapello was still expected to begin Sept. 17.
