Rockport full, Wanship dam expected to release higher flows

Submitted by Summit County

Summit County has been notified by the Weber Basin Water Conservancy District that Rockport Reservoiris expected to be completely full by late this evening, June 30. Due to warm weather and yesterday’s rain, snow melt runoff has increased in recent days. As a result of the reservoir being at its capacity, water flow leaving the Wanship dam is expected to increase water levels in the Weber River up to 10 percent from 1500 cubic feet per second (cfs) to over 1600 cfs this evening. This increase in flow has the potential to cause downstream flooding for properties along the river through Coalville between the Wanship and Echo dams. It is not expected to significantly increase water levels above the Wanship Dam. Residents have been preparing for this type of event for several weeks, filling sand bags and preparing their properties for the potential of flooding. Summit County is working closely with Coalville City to coordinate preparations for the increased water flow expected this evening, and minimize any potential flood damage. Residents and property owners along the river are being notified via a reverse-911 calling system. Summit County issued a message to 1,586 residences in Wanship, Hoytsville and Coalville warning residents of expected flooding. The increased water flow may continue for the next several days. Additional rain and higher temperatures can be expected to increase flooding potential. Summit County crews are available to help property owners whose occupied structures are threatened or affected by flooding. Property owners can call Summit County Dispatch at (435) 336-3600. Summit County reminds residents that extensive information about flooding and flood preparation is available at the County’s Web site at
