data. Inventories of surface water users must be consistent with regional hydrologic inventories reported by applicable state and federal agencies. The description of the hydrologic characteristics of streams, lakes, and shore regions must correspond to those of the United States Geologic Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), Soil Conservation Service (SCS), Corps of Engineers, or appropriate state and river basin agencies. Descriptions of all existing or proposed reservoirs and dams (both upstream and down- stream) that could influence conditions at the site must be provided. Descriptions may be obtained from reports of the USGS, United States Bureau of Reclamation (USBR), Corps of Engineers, and others. Generally, reservoir descriptions of a quality similar to those contained in pertinent data sheets of a standard Corps of Engineers Hydrology Design Memorandum are adequate. Tabulations of drainage areas, types of structures, appurten- ances, ownership, seismic and spillway design criteria, elevation-storage relationships, and short- and long-term storage allocations must be provided. 2. Appendix A, "Hydrologic Engineering Site Visits," to this SRP section details the purposes and procedures of the site visit. The site visit serves to acquaint the reviewer with the site and to provide an indepen- dent confirmation of the hydrologic characteristics of the site and adjacent environs. III. REVIEW PROCEDURES The information presented in SAR Section 2.4.1.1 is generally amenable to independent verification through cross-checks with other SAR sections and chapters, available publications relating to hydrologic characteristics of the site region, and by site visits. The review procedure consists of evaluating the completeness of the information and data by sequential comparison with infor- mation available from references. Based on the description of the hydrosphere (e.g., geographic location and regional hydrologic features) potential
