. Practically all dams inspected in the Cache la Poudre River basin fall into the high hazard and intermediate or large size category. Therefore, in the inspection results presented in this report, dams with the hydrologic capability to pass 100 percent of the PMF without overtopping are termed "adequate". Alternative floods were passed through the dams, with discharges being various percentages of the PMF discharges. Dams that pass 50 percent of the PMF but less then 100 percent of it are termed "inadequate". Dams that cannot pass 50 per- cent of the PMF are considered "seriously inadequate", Although the capacity to pass a PMF is a principal factor, structural deficiencies should be considered. Some of these are identified in the next section, which discusses dam safety inspection procedures. INSPECTION PROCEDURES A Phase I Inspection Report has been prepared under the National Dam Safety Program for about 30 dams in the Cache la Poudre River basin. The purpose of the inspection was to make a general assessment of structural integrity and operational adequacy. In order to identify hazardous dams expeditiously, the scope of the Phase I inspection was based on available engineering data, a detailed visual field inspec- tion, and a hydrologic analysis. The inspection determined needs for emergency measures or additional studies. The hydrologic studies were made to determine the capability of handling the PMF. During the field inspection, information on construc- tion, maintenance history, and operating procedures was gathered. A detailed inspection checklist covered each part of the dam, including the crest, upstream slope, downstream slope, abut~ent contacts, intake structure, outlet works conduit, stilling basin, spillway, gate struc- tures, the reservoir area, and instrumentation.
