This study identifies the drainage and flooding hazards within the watershed and develops alternatives to address those hazards. It is a comprehensive study that estimates flood and erosion potential, maps watercourses, identifies existing and potential problems and develops preliminary solutions and standards for sound floodplain and stormwater management.
This floodplain study was prepared to identify the extent and magnitude of flooding within the boundary of the park under existing conditions. The results of the analysis and the associated hydrologic/hydraulic model will serve as the base condition model for all future developments to aid in the planning and design process.
The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.
