In the past, home and business owners along the creek that comes from Mantua Reservoir, near Brigham City, Utah, had very little warning concerning high-water flows coming down the creek. To remedy this, Brigham City officials contracted with Intermountain Environmental, Inc., (IEI) to design and install a hybrid flood warning system for the watershed and water-delivery channel adjacent to Mantua Reservoir. The system would notify emergency personnel of the possibility of flooding or dangerous water levels in the creek.
