Abstract:

The Flood Control Work Group finds that flood problems exist in the Upper Colorado Region and that substantial flood damage can be expected in the future unless adequate flood damage reduction programs are implemented. It is estimated that the total average annual flood damage in 1965 was 2.8 million, and in the absence of additional damage reduction measures the flood damage will increase to 4.2 million by 1980, 6.8 million by 2000, and 10.6 million by 2020. The future flood damage reduction program consists of non-structural flood plain management measures, utilization of proposed multiple-purpose reservoirs for flood control storage, and construction of other structural flood control works where required. Flood control storage in future multiple-purpose reservoirs and small flood retarding structures would amount to 2,300,000 acre-feet. It is estimated the program presented would reduce the projected average annual flood damage to 3.3 million by 1980, 3.4 million by 2000, and 3.8 million by 2020. The damage projections are based on a modification of the OBERS baseline projections referred to as the Regional Interpretation of OBERS RI-OBERS.
