ALBENI FALLS DAM AND LAKE PEND OREILLE

The Dam consists of:

• The Powerhouse - passes water through three turbines to generate power and regulates lake level (fall drawdown and summer pool).

• The Spillway - passes water through 10 spillway gates to release water above powerhouse capacity (typically only used during spring runoff, not used for fall drawdown).

• Storage – the lake is generally operated between 2051 feet and

2062.5 feet, unless there are flood conditions. This equals about 1.0 maf.

ALBENI FALLS DAM: BASIC FACTS

Construction was completed in 1955.

ALBENI FALLS DAM: BASIC DETAILS

• Authorized purposes: Hydropower, Flood Risk Management, Navigation, Recreation, and Fish and Wildlife Conservation

(ENS).

• Powerhouse has 3 Kaplan generating units.

• Hydropower projects are 97.5% BPA funded.

• Dam, Spillway, FRM and Fish and Wildlife Conservation are joint funded between BPA and appropriation.

• Recreation and ENS value to the nation:

o Provides public access to over 4,000 acres of public land, 10 boat ramps, 139 campsites and 23 recreation/access areas.

o Approx. $25M of visitor spending within 30 miles of the lake.

(Corps only, does not include other public or private entities).

• Construction contract awarded SEPT 2022 for rehabilitation of 3 gates with 8 gates as options.

• Army Corps of Engineers initiated physical work on a gate rehabilitation contract in June 2023.

• The rehabilitation contract's purpose was to repair cracked welds identified during gate inspections and to re-paint the gate.

• As part of this rehabilitation contract:

• Removed Gate number 3, put our spare gate in place.

• Removed paint and completed in-depth gate inspection.

• During the gate rehab, steel defects were discovered in April 2024.

DISCOVERY OF SPILLWAY GATE DEFECTS

ALBENI FALLS DAM DEFECT LOCATIONS

• Base metal defects (holes and cracks in the steel)

• Should failure occur, the gate could fail and lead to crane operator injury and/or damage to the crane and bridge as well as loss of control of lake level.

SPILLWAY OVERVIEW

Feature Elevation (ft

NGVD29)

Probable Head** (ft NGVD29)

Summer Pool* (at Hope) 2062.5-ft 32.5

Winter Pool* (at Hope) 2051.0-ft 21

Spillway Crest 2033.0-ft 3

Maximum Normal Regulated Pool* (at Hope)

2062.5-ft 32.5

Top of Gate(s) 2065.0-ft 35

Top of Dam (Spillway Bridge deck-roadway elevation)

2097.0-ft

Pool of Record pre-dam* (1948, at Hope)

2071.6-ft

Pool of Record post dam construction* (1997, at Hope)

2065.74-ft

* Note that Lake elevations are measured at the USGS gage at Hope, Idaho, and not at the dam. Each lake elevation at Hope can result in multiple forebay elevations at the dam, depending on what the total project outflows are.

**Head is assuming minimum outflows and typical tailwater elevation of 2030

ft. Head at the dam is impacted by backwater from Box Canyon Dam, and high outflows can cause lower forebay elevations compared to lake elevations, which result in reduced head.

Weight (Approximate, based on existing gate weight):

• Upper Leaf: ~47,000 lbs

• Lower Leaf: ~ 57,000 lbs

Dimensions: 41-feet wide x 32-feet high, split leaf vertical lift gate

• Upper Leaf: 41-feet wide by 19-feet high

• Lower Leaf: 41-feet wide by 13-feet high

Quantity:

• Ten (10) total spillway gates

• One (1) spare gate for emergency and/or maintenance

Operated/lifted by gantry crane on the spillway deck.

PROJECT SCOPE

The work is performed according to but is not limited to the current versions AISC 325, AWS D1.5M/D1.5, and AWS D1.6/D1.6 as well as the Unified Facilities Guide Specification (UFGS) SECTION 05 59 20 FABRICATION OF

HYDRAULIC STEEL STRUCTURES.

Fabricating plants and fabricators may be required to have 5 years of documented experience on projects of similar scope and to be certified under the American Institute of Steel Construction (AISC) Quality Certification Program with one of the following certifications:

• Certified Bridge Fabricator - Intermediate (IBR)

• Certified Bridge Fabricator – Advanced (ABR)

• Certified Hydraulic Fabricator – Standard (HYDS)

• Certified Hydraulic Fabricator – Advanced (HYDA)

The fabricator will be required to hold a Fracture Control Endorsement (FCE) under the AISC Quality Certification Program, in addition to one of the certificates above.

STRUCTURAL FABRICATOR REQUIREMENTS

• The painting contractor must be certified by the Association for Materials Protection and Performance (AAMP) with SSPC QP 3 certification for all shop surface preparation and coating application.

• Each painter will be required to get individually certified prior to painting. This is typically done via a 3rd party test agency or government witnessed test plate painting.

• The gates will be painted with 5-E-Z vinyl paint.

TECHNICAL QUALIFICATIONS FOR PAINTING

• ASTM A-709 Grade 50 Steel required for the majority of new gate fabrication.

CONCEPTUAL-STRUCTURAL

Lifting Beam

Upper Gate Leaf

Lower Gate Leaf

• Electric gear motors in lifting beam for actuation of latching and dogging mechanisms.

o Latching of lifting beam to top leaf of gate.

o Latching of top leaf to bottom leaf of gate o Dogging of gate in the gate slot.

• Mechanical linkages in top leaf of gate for latching and dogging

• Stainless steel wheels with spherical self-lubricated bearings in place of roller chain.

CONCEPTUAL-MECHANICAL LINKAGES

• Springs for extension and retraction of latching pins.

• Actuated from lifting beam with a plunger.

• Stainless steel wire rope linkages.

• Bell cranks for change of direction.

• Dogging mechanism similar.

CONCEPTUAL DESIGN – LATCHING MECHANISM

CONCEPTUAL DESIGN - WHEELS

• 16-inch Diameter by 5-inch Wide wheel

• Spherical self-lubricated bearing

• 17-4 PH Stainless steel rim, sphere and axle.

• Nitronic 60 fasteners

CONCEPTUAL-DELIVERY ACCESS

• Removal and disposal of gates may require remediation of hazardous paint and/or materials.

• Transition of existing gates for disposal expected to be the same transition locations for delivery of new gate(s).

• Removal of existing gate(s) would occur after replacement gate fit test is completed, or later as determined by Government based on ongoing and/or required operations.
