parameters. Copies of the relevant sections of the Final EIS and Final BO can be downloaded <br />from the Program Web site (www.PlatteRiverProgram.com) or obtained from Chad Smith. <br />Given this framework, the study should provide information sufficient to estimate changes in the <br />physical environmental parameters identified above, across the identified range of flows and the <br />three scales of ineasurement intervals, that occur during the study period and as can be <br />determined from historic information. The intent should be to draw inferences to the types of <br />process changes that would occur in the system as a result of river stage changes: <br />a. Information will be sufficient to determine if Program water activities can be statistically <br />identified (significant beyond the error of the gauging equipment) from base flow <br />conditions (Hypothesis X-Y Graph PS-2). <br />b. Information will be sufficient to detect if Program water activities have a statistically <br />significant impact on stage, velocity, temperature, turbidity, substrate, or channel <br />morphology (Hypothesis X-Y Graphs PS-4, PS-6, PS-9). <br />This includes an emphasis on floodplain connectivity and the inundation of otherwise terrestrial <br />habitat (not out of the high banks), and how both of these factors vary with flow. <br />Proposals should include the scope, timeline, and budget for developing a detailed protocol for <br />estimating the effects of stage change on the identified physical parameters. The protocol will be <br />reviewed by a selected Program sub-group before being finalized. The final protocol will be in <br />sufficient detail to identify all aspects of data collection, analysis, reporting, and deliverables for <br />the overall project. The final protocol and detailed budget estimate for actual implementation of <br />the protocol will be provided to the appropriate Program sub-group andlor Advisory Committee <br />for review. Approval of the protocol and budget by the Governance Committee is needed prior <br />to the contractor proceeding with protocol implementation. <br />AVAILABLE INFORMATION <br />In addition to the Program Document and its Adaptive Management Plan (Attachment 3), several <br />additional sources of information are available to assist potential contractors in responding to this <br />RFP. All of these documents can be accessed either from the Program Web site <br />(www.PlatteRiverProgram.com) or by contacting Chad Smith. <br />1) In the late 1980's, the Nebraska Game and Parks Commission (NGPC) recorded transect <br />information on sections of the lower Platte River for use with Instream Flow Incremental <br />Methodology analysis. While this information may no longer be current, it allows historical <br />comparisons in some stretches of river. <br />2) Multiple cross-sectional transect data collected by Mussetter, Inc. as part of a NGPC <br />evaluation of the Sarpy County/Clear Creek Levee project. <br />3) Cumulative Impact Study for the Lower Platte Corridor Alliance that may have some overlap <br />with this study. The information includes a digitized series of aerial photographs of the <br />lower Platte reach, and a GIS database covering a decadal time-step.
