Mapping of amount of sediment storage at the diversion dam, <br />Estimate yardage to be removed and cost. Inspection of diversion <br />gate and sluice gate, estimate replacement cost. Estimate cost of <br />concrete repairs, Evaluate the addition of a sand trap in the <br />diversion pipeline. Evaluate ~ir release valves on the pipeline, <br /> <br />2. Survey profile and cross-sections of the Upper Canal. <br />Calculate hydraulic profile at various flows. Calculate flows in <br />each canal segment to size pipe,line or ditch lining and estimate <br />construction costs. Locate all lateral gates and estimate the <br />replacement needs and costs, Make ditch loss measurements to <br />determine segment losses. <br /> <br />3. Survey Brush Hollow spillway cross-section, Calculate the <br />hydraulic capacity, Determine the watershed area and peak inflow. <br />Determine the design of an inlet structure from the upper ditch. <br />Estimate construction costs. Inspect outlet tube and gates. <br />Evaluate seepage control around embankments. <br /> <br />4, Survey profile and cross-sections of Lower Canal from Brush <br />Hollow Dam to Third Street. Make ditch loss measurements to <br />determine segment losses, Determine sizing of ditch lining or <br />pipeline and estimate construction costs, Calculate hydraulic <br />profile. <br /> <br />JlVID /mmd <br /> <br />Very truly yours, <br /> <br />9i.
