Y--OR-KLAMATH FALLS FWO-PHASE 5 CONSTRUCTION

Klamath Falls New Hatchery Phase 5 will add earthen lined aquaculture ponds to the site to increase the capabilities of the sucker fish hatchery. This phase of the project includes a 0.30 acre earthen, lined pond for water storage known as the Head Pond, and up to three earthen, lined ponds for aquaculture with harvest kettle structures built into their berms, water supply, and drainage. The aquaculture ponds will typically be 5 to 7 feet deep with berms that are 6 to 12 feet tall and vary in size from 1/12-acre to 1/2-acre. Supply pipelines, drainage pipelines and access roads will be constructed around each of the ponds. Phase 5 will also include re-routing of approximately 415 feet of 8-inch diameter geothermal supply (GS) pipeline. Construction work needed to facilitate the project includes excavation, fill placement, grading, temporary erosion and sedimentation control, permanent seeding, pond liners, elevated bird predation netting system, cast-in-place concrete structures, paving and crushed rock road surfacing, pressurized pipelines for geothermal water distribution, and gravity pipelines for drainage. Through this sources sought, USFWS is also seeking industry feedback on the proposed design. We are looking for industry recommended best practices that should be included in our design package and if there are any issues with the design that would present challenges to construction.
