5 <br />THE 1975 ASSESSMENT PROCESS <br />OVERVIEW <br />The 1975 Assessment will identify and describe the Nation's <br />severe water- related problems -- those problems which become <br />severe because of an imbalance between - current (1975) supplies and <br />estimates of water use for a prespecified range of assumed future <br />conditions -- using the four -step assessment process displayed in <br />Figure 1 and described in the following material. <br />It is basic to the assessment process that both numerical and <br />narrative evaluation techniques be used to determine -- to the extent <br />possible -- the following factors: <br />o The magnitude of deficiencies within and among the <br />geographic units and the range of assumptions on future <br />water use conditions in those areas. <br />o The economic, environmental, and social impact (both <br />beneficial and adverse) of not having an adequate supply <br />of water with certain major properties (volume; surface <br />area, depth and cross section; flow characteristics; and <br />aquatic habitat) to satisfy the assumed future use conditions. <br />o The overall problem severity within each geographic <br />unit, determined from the overall weighted impact of <br />not having a balanced adequate supply with the desired <br />properties to meet all uses. <br />o Problem urgency -- i, e., time periods in which <br />management, planning, research, and data - collection <br />actions are required to resolve the identified deficiencies <br />and to alleviate the economic, environmental, and <br />social impacts therefrom. <br />As stated in the foregoing, problem severity is measured in terms <br />of the economic, environmental, and social impact of not having adequate <br />water supply properties. The following requirements will be analyzed <br />under assumed future conditions: <br />
