Gold Ray Dam Interagency Technical Team Meeting

NEPA Update Deconstruction Plans Hydraulic Modeling Next Steps Agenda

Upstream habitat (wetlands, fish, frogs, riparian areas) Well levels Downstream domestic water intakes Sediment quality Recreation Economic impacts (fishing and river guides) Alternatives – dam rehab and power generation NEPA Update EA Issues from Scoping Mtg

Section 1 – Introduction Section 2 – Purpose and Need and Alternatives Purpose and need – complete No action Alternative 1 – Dam Removal Deconstruction plan Restoration plan Alternative 2 – Dam Rehabilitation Dam, forebay walls, etc. (structural) Fish Ladder Fish Screening Power generation – optional? NEPA Update EA Progress

Section 3 – Affected Environment and Environmental Consequences Section 4 - Preparers and Agencies Consulted Section 5 – Abbreviations/Acronyms Section 6 – References NEPA Update EA Progress

Dam complex SHPO coordination Determination of eligibility (DOE) nearly complete Likely eligible for National Register Removal likely adverse effect but mitigated Archaeology SHPO coordination done DOE underway – no shovel testing required NEPA Update Cultural Resources

Level 1 – based on records and site visit; no testing Look for indicators for contamination Recommend testing locations in power house and former transformer sites NEPA Update Environmental Site Assessment

Biological Assessment Content largely completed Confirm the action area Incorporate demo/restoration plan information Project Approach

Wetlands Report Submitting 2 wetland reports: Delineation Report and Indirect Wetland Impact Report Reports are drafted; waiting for 2 year event modeling to finalize maps Project Approach

Schedule Review draft EA and permit applications in middle of January Draft EA – 30 day review and revision Goals: Submit BA and permit applications in early February EA out for public review in mid to late February Project Approach

Deconstruction Plan Multi-step plan with controlled drawdown of reservoir Minimizes risk for County Ensures dam removal and fish passage when complete Project Approach
