6 Hydrology Modeling Update Hydrologic analysis was performed on gage and model data (Geoscience, Wildermuth) for HCP reaches Comparison of With and Without Covered Activity hydrographs, exceedance analysis, total acre-ft diversions Results showed need to revise model Geocience data Adjust points of diversion Change diversion rates into recharge basins Combine Enhanced Recharge model with Active Recharge Extend model downstream to account for Rubber Dam ~ 3 months - New results will be reevaluated along with gage and Wildermuth data for effects analysis icfi.com 6

7 Potential Effects Approach Overview and Examples Hydrology Verification Best available information Modeling Tool with Comparable Results Monthly Exceedance Flows 5%,25%,50%,75%,95% Without Covered Activities With Covered Activities Estimate Wetted Perimeter ( Surface Area) Lidar HEC-RAS Habitat Quantity (Next Steps) Estimate Effects of Covered Activities icfi.com 7

13 Finalize Covered Activities icfi.com 13

14 Finalize Covered Activities Step 1: Review Covered Activities Information Evaluate and confirm the Covered Activity information you have provided to date. GIS data text describing qualitatively and quantitatively the construction, operations, and maintenance of each covered activity points of diversion or discharge current and proposed future diversion flow rates current and proposed future basin capacities Step 2: Online Meeting with ICF Review Covered Activities information with ICF in online meeting Provide all corrections to text, GIS, and potential hydrologic effects the corrected covered activity document to ICF prior to this online meeting. Step 3: In Person Meeting with Valley District Meet with Valley District in Early December to confirm final Covered Activity information Final covered activity information must be confirmed by each participating water agency during the first week of December. icfi.com 14
