Title:

M: 174 - Conduct Feasibility Study for Breaching Dam in Cedar Creek

Description:

Evaluate and develop selected projects from those identified in the Upper Columbia and Sanpoil Habitat Restoration Plan (Contract #73548 Rel 21). Priority reach "Cedar 1" is a 3.35 km portion of Cedar Creek a tributary to Barnaby Creek, which is a direct tributary to Lake Roosevelt. Cedar 1 is primarily impacted by an earthen dam impounding a small pond (1,490 m^2). The outlet of the dam is a complete barrier to fish passage.

Preliminary estimates of size and stream characteristics derived from habitat survey data indicate a height of 4 m (13.1 ft), average channel width of 2 m (6.6 ft), and average slope of entire priority reach of 6.1% gradient (range of 4.5% to 17%). As part of the feasibility study, these dam and stream characteristics will be verified to determine HIP compliance requirements.

Project development tasks include: evaluating the potential ecological, chemical, and physical changes to the stream and habitat post-dam removal. Land ownership and landowner willingness need to be verified. A preliminary study to determine the quantity and composition of fine sediments impounded behind the dam is needed to determine engineering needs for breaching and sediment disposal.

Depending on the findings of this preliminary planning phase and the results of the subsequent design phase (WE N:175. Produce Design) and cost estimate, implementation of dam removal is scheduled to begin in FY2021.

WE Agreement Type:

Contracted

Deliverable Specification:

A plan that confirms landowner willingness and identifies the potential ecological, chemical, and physical changes to the stream and habitat post-dam removal to determine engineering needs for dam breaching and sediment disposal.

A	EC	Environmental compliance requirements complete	2/1/2020	3/31/2020	Concluded	Jamie Cleveland (Inactive)	12/16/2019 4:38:21 PM
		Description: On-the-ground work associated with this work element cannot proceed until this milestone is complete. Milestone is complete when final documentation is received from BPA environmental compliance staff.
B	HIP	Discuss HIP ESA coverage with BPA EC Lead and obtain risk determination	2/1/2020	8/31/2020	Canceled	Jamie Cleveland (Inactive)	12/16/2019 4:38:21 PM
		Description: The EC Lead will determine if work under this work element may be able to have full ESA-coverage (NMFS & USFWS) under the Habitat Improvement Program Biological Opinion (HIP). The HIP has expanded coverage for projects that may pose a moderate to high risk of impacting an ESA-listed species or critical habitat that would normally require a Biological Assessment. For work that qualifies, projects will undergo a review by the EC Lead and Engineering Technical Services (ETS) team. Before conceptual design commences, contact the EC Lead for HIP consideration, instruction, and information needs and requirements for coverage eligibility.
C		Confirm landowner willingness	4/1/2020	8/14/2020	Canceled	Jamie Cleveland (Inactive)	12/17/2019 7:38:25 AM
		Description: Submit landowner agreement to BPA that documents acknowledgement/approval of project. The COR can provide an agreement template. To be completed during planning phase. Verify the land ownership and contact owner to obtain permission to survey earthen dam to confirm height estimates and stream reach characteristics. Also confirm landowner willingness to breach dam for fish passage. A conservation easement or similar agreement will be uploaded to CBfish to document authorization for access to the property, dam breaching and sediment removal activities, and post implementation monitoring.
D		Verify dam and stream characteristics	5/1/2020	8/31/2020	Canceled	Jamie Cleveland (Inactive)	12/17/2019 7:38:25 AM
		Description: Obtain accurate survey elevations to determine whether dam height meets "small dam" criteria for HIP coverage as well as site specific stream characteristics (active channel width, channel slope). This will also inform the necessary guidelines for review, e.g. Low Risk, Medium Risk, High Risk. Preliminary data indicates a dam height of 4 m, average stream gradient of 6.1%, and average stream width of 2 m which. Once confirmed, these dam and stream characteristics will also inform engineering design needs for development of a Request for Proposals (RFP) to be undertaken in WE N: 175. Produce Design.
