Wikieup Dike

Date Completed: June 2011
Cost: $572,833.47
$251,827.81 funded by ADOT

A portion of the Town of Wikieup is protected from flood flows by a dike approximately 4,700 feet in length, located about 0.8 miles west of Highway 93 and just south of the Wikieup landing strip. According to Mohave County historical records, the dike was constructed in the early to mid 1960’s. In addition to the dike structure itself, a channel and series of reservoirs were initially constructed on the upstream side of the dike, presumably to work together in order to provide the necessary flood protection.

In late 2007, an evaluation of the structures was completed in order to determine the adequacy and extent of protection the dike, channel and reservoirs were providing at the time. The evaluation determined the need for the following improvements: 1) A rehabilitation of the channel, dike and reservoirs. 2) Reconstruction of the downstream wash left bank at a historic flow split.

Mohave County partnered with the Arizona Department of Transportation in order to complete the improvements in June 2011.
