EXPLANATION OF INUNDATED AREAS An inundation study was performed along the Cache la Poudre River between Horsetooth Reservoir Dams and Fort Morgan, Colorado. The inun- dation maps were developed using technical guidelines established by the Bureau and the National Weather Service. The maps reflect conditions of an extreme nature, with a very small probabil ity of occurrence. The maps do not reflect upon the structural integrity of any of the dams on Horsetooth Reservoir. There are 12 maps. An index sheet is also provided. The mapped section of the Cache la Poudre River channel is situated in gently sloped areas between the dams and the confluence of the South Platte River approximately ag to 93 miles downstream. Much of this valley is agricultural farmland, with extensive development, par- tic!Jlarly in Fort Collins. A few cities and towns are also located along and near the river channel. A dam failure during a probable maximum flood would inundate or cause severe damage to the following areas: Fort Collins Timnath - Laporte Interstate 25 Windsor Kodak Plant Portions of Greeley Hardin Masters Orchard Goodrich Weldona Low lying areas of Fort Morgan The inundated areas shown on the maps collectively reflect areas that would be affected during a dam failure and probable maximum flood. Due to the topography and difficulty in mapping inundated areas below the dams, high spots in these areas are very likely. Feeder canals leading into Fort Collins may also intercept flood flows which would 6
