Areas downstream of Davis Dam <br /> <br />experienced the greatest incidents of flood damage and <br /> <br />economic loss, most of which occurred to structures and <br /> <br />businesses within the floodway. <br /> <br />Damage to recreational <br /> <br />facilities was widespread, affecting beaches, campsites, boat <br /> <br />docks, launch sites, and businesses servicing these <br /> <br />activities. <br /> <br />Substantial revenue losses were incurred by <br /> <br />businesses due to reduced recreation along the river during <br /> <br />the period of peak releases. <br /> <br />Flood-related damages below Davis Dam sustained by the <br /> <br />Bureau of Reclamation facilities have been estimated to be <br /> <br />about $40 million. Damages to the private sector downstream <br />of Davis Dam have been estimated to be in the order of $30 <br /> <br />million. <br /> <br />Another $10 million of estimated losses were <br /> <br />sustained by state, county, and local governments in the <br /> <br />lower Colorado River area, bringing the total estimated <br /> <br />damages below Davis Dam to roughly $80 million. The revenue <br /> <br />losses to businesses along the river due to the high flows <br /> <br />are not included in this estimate. <br /> <br />Technical Changes to River Operations <br />and Runoff Forecasting Procedures <br /> <br />Data on the weather events and subsequent runoff that <br /> <br />occurred in 1983 have-been incorporated into the Colorado <br /> <br />River Forecast Center data base, resulting in an increase in <br /> <br />the uncertainty values added to the mean monthly forecast to <br /> <br />obtain the maximum forecast.
