FISH PASSAGE PROJECT PURPOSE AND NEED

▪ AFD is currently a fish passage barrier for bull trout.

▪ Without the new passage facility, AFD is projected to be the only upstream passage barrier in Pend Oreille River and Clark

Fork River basins.

▪ AFD prevents entrained bull trout from accessing high quality habitat and cold-water refuge above AFD in Lake Pend Oreille and upstream tributaries.

▪ Biological connectivity for upstream migrants to critical habitat above AFD is absent.

▪ Not under FERC

Contract: Design and construction services for a new Fish Passage Facility located at Albeni Falls

Dam (AFD), Oldtown Idaho.

Site: Located at Albeni Falls Dam

Features of Current Concept Design:

1. Water Supply

2. Entrance Structure and Pool

3. Fish Ladder

4. Pre-sort Pool

5. Fish Lock

6. Sorting Area

7. Truck loading

Tentative Schedule

• Phase 1: Q3 FY2023

• Phase 2: Q1 FY 2024

• Award: Q4 FY2024

SCOPE: DESIGN-BUILD CONTRACT

• Albeni Falls Dam is located near the Washington/Idaho border approximately 1 hour North of Spokane on the Pend Oreille River in Bonner County, Idaho.

• The project includes a 90‐foot‐high concrete gravity, gate‐controlled spillway that is 775 feet long. Overall length, including the non‐overflow section (island) is 1320 feet.

• The Albeni Falls Dam Project has five main purposes: Power Generation, Flood Control, Navigation, Recreation, and Fish and Wildlife Conservation

Power Generation

• Albeni Falls is a low head dam with the average elevation drop from upstream to downstream at 30 feet during summer pool.

• It is part of the Columbia River system, providing water storage for downstream hydroelectric projects on the Pend Oreille and Columbia Rivers.

Flood Control

• The reservoir level is lowered in the fall for power generation and to make room for the spring runoff.

• Albeni Falls Dam spillway is designed pass up to 350,000 cubic feet per second with all gates open.

Navigation

• Albeni Falls releases water throughout the low winter months to improve navigation on the Columbia

River.

Recreation

• During the summer months the lake level is maintained at 2062 to provide safe and consistent recreation.

Fish and Wildlife Conservation

• Albeni Falls provide flow augmentation for Salmon on the Columbia.

• One federally listed species (bull trout, threatened) and several State listed sensitive species occur on project lands and waters.

• Feasibility-level design and cost estimate.

• Incorporates changes from completed reviews:

• NWD (2015 and 2017)

• ATR (2015)

• BPA and Kalispel Tribe (2015 and 2017)

• Remaining reviews:

• ATR (2017)

• Public review (2017)

SPECIAL REQUIREMENTS / CONSIDERATIONS

Geotechnical

• Geotechnical investigations have been completed for concept design

• USACE will provide a Geotechnical Baseline Report (GBR) for bidding purposes

• Contractor will be required to provide GBR for construction

Survey

• Survey of the site based on the concept design have been completed

Environmental (NEPA)

• Has been completed with the exception of the water quality certification

• Project site does contain a feature of historical significance (log chute)

• Contained a 35% concept level design

Work near Operating hydroelectric dam

• Water levels of forebay and tailrace

• Water management during dam operations, ie. spill season

• Dam safety during tunneling and blasting operations

• Limited staging areas

• Historic district with regional significance

Facility Operations

• Year round except for extreme weather – winter freezing conditions and summer lethal temperatures

Project Success – Facility Commissioning will be required

• Will be defined in the RFP, for example injury to fish

• Will likely include installation of monitoring equipment – pit-tag readers, cameras, etc.

Water quality certification

• Water treatment and BMPs will be completed during design

• Will be a submittal under the contract to allow for coordination with IDEQ

• Final BMPs will need to be developed during design

• Must receive final WQC from IDEQ prior to construction

Care and diversion of water and cofferdam installation

• Will be contractor’s responsibility

• Expect that there will be multiple submittals

• Minimize incidental take of bull trout per BiOp during cofferdams, blasting, drilling, proof of concept, etc.

• In water work windows, ie. blasting, fish safety

Dam Safety

• Will be contractor’s responsibility

• Detailed blasting plan submittal will be required

• Must be approved prior to construction
