Reade (2000) reported mean suspended solid levels at four sites along the lower Platte <br />River by date for 1998 and 1999; these were recorded as follows: <br />Lower Platte River Suspended Solids = (m &L) <br />Date I Mean <br />11 May 1999 <br />304 <br />25 May 1999 <br />676 <br />7 July 1999 <br />228 <br />20 July 1999 <br />687 <br />3 August 1999 <br />146 <br />14 May 1998 <br />157 <br />11 June 1998 <br />767 <br />23 June 1998 <br />439 <br />7 July 1998 <br />783 <br />3 August 1998 <br />250 <br />Hydraulic Modeling <br />Hydraulic data from two studies from the mouth of the Platte to the Elkhorn River are <br />available. The study sites near Louisville and Cedar Creek, Nebraska, were selected by <br />an interagency team of Nebraska Game and Parks Commission and U.S. Bureau of <br />Reclamation biologists and hydrologists according to the guidelines of the Instream Flow <br />Incremental Method (Bovee 1982). Further information on site selection and site maps <br />are contained in NGPC (1993). <br />The hydraulic data were collected in 1985, 1987, and 1988, and consisted of: 1) bed <br />profile data and bed elevations from headpin to headpin across each transect, 2) distances <br />across the channels with corresponding depths and velocities, and 3) substrate fish cover <br />distributions. The hydraulic data has been processed using Physical Habitat Simulation <br />(PHABSIM) procedures, and calibrated hydraulic files data files have been produced to <br />represent hydraulic relationships at a range of simulated river discharges.
