0 <br />PRRIP — ED OFFICE FINAL <br />12/10/2007 <br />In accordance with the Program's Adaptive Management Plan (AMP), the study should provide <br />sufficient data to evaluate the effect of changes in river stage over a range of flows on a micro, <br />meso, and macro scale. The following example is provided to help define these terms and <br />provide a framework for the range of flows to be considered and the interval measurements that <br />need to be made: <br />River Gage: Louisville, NE (Station ID 06805500) <br />Range of River Flows: 5,000 cfs to 39,000 cfs (bankfull flows) <br />Precision Level: o con i ence <br />Possible Measurement Interval: Every 1,000 cfs (roughly 0.1 foot of stage change) <br />In responding to this RFP, potential contractors should provide information on the needed <br />methods to obtain this data, the appropriate discharge /stage measurement intervals necessary for <br />achieving the desired level of precision, and the efficacy of applying these methods over a larger <br />range of flows. In addition, potential contractors can use guidance provided by the Program's <br />Final Environmental Impact Statement (EIS) and the Final Biological Opinion (BO) to better <br />understand the types of flow changes of concern and the related impact on the identified physical <br />parameters. Copies of the relevant sections of the Final EIS and Final BO can be downloaded <br />from the Program Web site (www.PlatteRiverProgrrain.or ;) or obtained from Chad Smith. <br />Given this framework, the study should provide information sufficient to estimate changes in the <br />• physical parameters identified above, across the identified range of flows and the three scales of <br />measurement intervals, that occur during the study period and as can be determined from historic <br />information. The intent should be to draw inferences to the types of process changes that would <br />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 (AMP 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 (AMP Hypothesis X -Y Graphs PS -3, 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 and /or 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 />4 <br />
