Documentation of Hvdroloav Models and Habitat Models <br /> <br />Detailed technical data and information will be included in supporting <br />documents. The supporting documents for the study will include users' <br />guides for the hydrologic models and habitat models. The hydrologic and <br />habitat models to be developed for the Platte River basin will include a <br />monthly North Platte River, South Platte River, and Platte River <br />operations model, daily operations models for select segments of the <br />Platte River Basin, a sediment transport model for the Platte River, and <br />species habitat models. <br /> <br />v. Existinq Data and ProDosed Data AcauisitioD <br /> <br />a. Data Reauirements <br /> <br />Hydrological and biological data requirements for this evaluation are <br />discussed below. The hydrological data requirements are historic flow <br />records (monthly and daily), historic diversion records (monthly and <br />daily), climatic data (precipitation, temperature, and evaporation), <br />land use data, river channel data, and municipal use data. Other data <br />required to do a hydrological analysis is physical data of river struc- <br />tures; dams, reservoirs, diversion darns, multiple channel flows, and <br />power plant size. <br /> <br />The biological data requirements are species' use information of the <br />habitats they use. The habitats used include in-channel and out-of- <br />channel riverine areas along the South Platte, North Platte, and Platte <br />Rivers. The physical parameters relating to the quantity and quality of <br />species habitat in the Central Platte have been defined by species <br />workshops and published research. Chapter 3 of the Platte River <br />Management Joint Study Biology Work Group final report discusses these <br />references and the species habitat use. Additionally, every reasonable. <br />effort will be made to locate and acquire other pertinent information. <br /> <br />b. Collection and Analvsis of Data <br /> <br />Hydrologists and technicians will assemble and analyze the flow records, <br />past operation, and climatological data to develop a water supply <br />operation study of the Platte River basin. Assembling the data will <br />require an extensive work effort as raw data exists in many locations. <br />Entities possessing data are State natural resource agencies and <br />Universities, Federal agencies (Corps of Engineers, Bureau of <br /> <br />8 <br />
