Scope of Work 4-10-2009 <br />Colorado River Basin Nonconsumptive Needs Quantification <br />■ Riparian: The initial riparian inventory will use both aerial photography and ground truthing <br />to describe the existing riparian conditions, notes on vegetative species composition, general <br />locations of native riparian corridor and ranchland. <br />■ Aquatic Habitat: Distinct aquatic habitat reaches exist within this reach of river, a canyon <br />bound reach and meandering reach. General characteristics of these habitat reaches will be <br />described using data from topographic maps, aerial photography, and field mapping of short <br />sections (1 J 2 mile or less} of the river. Aquatic species information will be acquired from the <br />Colorado Division of Wildlife data or other sources. <br />■ High Flow Measurements: The initial site set up and high flow measurements will be <br />collected. <br />Schedule: <br />Task 1.1 will be completed between March 31st and june 30th, 2009. <br />Task 1.2 Completion of Data Collection <br />Cost: $34,242 ($34,242 WSRA, $0 Match) <br />This task is contingent on funding of Task 1.1. This work assurnes that River 2D will be the <br />model used for data analysis and habitat quantification. As such, the field data collection will be <br />consistent with those data needed to calibrate and simulate River 2D for a range of flows. The <br />initial data collection for high flow will be collected in Task 1.1. Task .1.2 data collection will <br />include mid flow and low flow data including river topography. <br />Schedule: <br />Task 1.2 will be completed between July 1st and November 15th 2009. <br />Task 1.3 Data Analysis, Model Calibration, Model Simulation and Report Cost: <br />$96,390 ($0 WSRA, $96,390 Match) <br />Data analysis, model calibration, model simulation, and report. This work will include data <br />summary from the field data provided in Tasks 1.1 and 1.2; input of data for model calibration <br />and model simulations. Model simulations will include hydraulic and GIS habitat analysis for a <br />range of flows for up to five species at each site. A report will be prepared to document field <br />data collection, model calibration and simulation and results. This effort is in coordination with <br />the associated Wild & Scenic alternatives process. <br />Schedule: <br />Task 1.3 can begin during data collection; however, the majority of the work will be completed <br />after all field data collection is complete. Task 1.3 would be completed between September 15th, <br />2009 and March 15th, 2010. <br />Task 2 Apply Watershed Flow Evaluation Tool throughout Colorado <br />River Basin <br />Completion of this task is based on the following assumptions: <br />� <br />Page 3 of 15 <br />
