Project Description:

The CEDE - Civil Engineering Department is requiring a proposal from the group of student engineers to provide comprehensive engineering efforts related to the improvement of fish passage in Ente Creek and within the Lake Roosevelt drawdown zone.  Due to the construction of Grand Coulee Dam, there has been significant loss of fish habitat that was vital to salmon, steelhead and trout populations in the Columbia River, the Spokane River and the surrounding tributaries. Currently Enté Creek flows into the Spokane Arm of Lake Roosevelt and has limited spawning opportunities for salmonids. The creek has excessive beaver activity at the mouth of the stream that creates large pools upstream of the beaver dam for salmonid rearing, but the heights of the dams eliminate passage for salmonid spawning. Kokanee salmon and redband trout stage at the mouth of Enté Creek, but cannot enter the stream to spawn. This stream also submerges into the substrate about ¼ mile from the mouth, so usable habitat for juvenile salmonids is limited. Drawdown by Grand Coulee Dam also blocks passage for spring spawners as the stream can submerge into the sediment at the mouth.


The Spokane Tribe would like to improve spawning opportunities for current as well as future salmon and trout populations by designing and creating a spawning channel in Enté Creek. This project will require an analysis of local hydrology and hydraulics, selection of several design options, assessment of those design options based on specified criteria (cost, constructability, effectiveness, etc) and weights, sediment transport analysis, habitat assessment, and hydraulic channel and fish passage design, while accounting for Beaver activity in the area. The goal is to create a stream channel within the drawdown zone that allows passage and prevents water loss and maintains complexity and resting areas for spawning salmonids. By creating a spawning channel like those created in Canada, Enté Creek could provide greater spawning opportunities for the current salmonid populations as well as salmon and steelhead that may be reintroduced into Lake Roosevelt when fish passage at Grand Coulee and Chief Joseph dams are created.


The project will produce a conference or journal publication and a final report to submit to the sponsor. Students will be responsible to make required presentations of the project activities and may also attend an appropriate conference.



The proposal evaluation process will be determined by the project advisor in conjunction with the CEDE, the project sponsor, and the CEDE Design Advisory Board.  It will be based on the organization of the project efforts reflected in the proposal and the educational goals achieved in the completion of the proposal.  Note that some efforts in the project are oriented to achieve educational goals that are not required to achieve the project sponsors goals.



The lower Spokane River below Little Falls Dam has become a portion of the Lake Roosevelt reservoir system as a result of Grand Coulee Dam’s backwater. At full pool in Lake Roosevelt, Ente Creek, a sandy tributary to Lake Roosevelt, is filled in with fine sediment deposits smothering spawning gravels. During Lake Roosevelt drawdown, the mouth of Ente Creek returns to a free flowing system with the original channel being exposed during spawning season.  However, shallow depths in Ente Creek make it difficult for native salmon and redband trout to migrate upstream to spawn and with sand covering potential spawning runs within the drawdown zone it also decreases critical spawning habitat. In addition, there is significant Beaver activity in Ente Creek, and their dams create fish passage barriers with the creek. 



The project team must familiarize themselves with the existing condition of the project in order to properly prepare the project proposal.  The sponsor may have survey and field data necessary to complete the modeling and analyses portions of this project.  The sponsor should be contacted by the design team to determine what data is available for use. 



The student project group will, at a minimum, provide the following efforts and deliverables in the completion of the project addressed in this proposal:


Scope of Activities Required to Meet Project Goals


Task 100                                Project Management and Coordination

The student group shall organize, manage and coordinate the efforts required to accomplish the project using standard project management and contract administration techniques. Key management activities are identified below:


            Sub-Task 110                        Kick-off Meeting

The Student Team will conduct a kickoff meeting with their project advisor and sponsor liaison’s to gain familiarity for the project and to solicit input, gather available data and information.


            Sub-Task 120                        Routine progress-review meetings

Routine progress-review meetings will be conducted on a regular basis as follows:

a.      Weekly progress reports are required and are to be submitted electronically to the advisor by 5:00 pm each Thursday. Weekly progress reports must include, at a minimum, activities completed by each team member for the current week, expected work for the upcoming week, and updates to the project design budget and schedule.

b.      In addition, a complete hardcopy record of the project reports and files must be maintained by the student team and be made readily available during consultations with the advisor. Typical method would be a project notebook. The advisor and liaison will ask to review this notebook periodically to discover the status of the work being completed. 


            Sub-Task 130                        Regular Advisor and Liaison Meetings

After the kick-off meeting, the Student Team will meet weekly with the project advisor, and will also meet when needed with the project liaisons.  All meetings with advisor and liaison’s MUST be arranged by members of the Student Team in advance (at least 2 days prior) and include a proposed meeting agenda sent to the advisor or liaison prior (at least 2 days) to the meeting.  All meetings must be documented by the Student Team in the form of meeting minutes with copies distributed within 3 days of the meeting to all team members and the project advisor and liaison’s, as above.


      Sub-Task 140            Quality Assurance/Quality Control

The Student Team will perform a methodical QA/QC effort in a manner suitable to the project advisor and liaison, to prevent incorrect, sub-standard or dangerous results from being included in the end of semester project reports.


      Sub-Task 150            Project Schedule / WBS /Gantt Chart

            Subtask 250 - Stream Stability and Habitat Characterization

            Subtask 260 - Lake Roosevelt Drawdown Schedules

            Subtask 270 - Rainfall/Hydrologic Analysis


Task 200 Deliverables

  • Electronic copy of literature, data and mapping, reports or surveys completed for the project and to be included in the project report.
  • Bibliographic references and annotations for significant literature used, suitable for use in conference publication.
  • Summary of safety and legal issues addressed in design.


Task 300                                Project Design Efforts

The student team will develop plans, drawings, analysis, comparisons, and other design work required to successfully achieve the project goals. The specific project approach will be determined by the team in the project proposal. The final scope should include at a minimum the following sub-tasks (more may be added):

            Sub-Task 310                        Stream Physical Characterization

Analyze survey, sediment, and vegetation data to characterize stream stability and habitat conditions.


Sub-Task 320                        Stream Biological and Ecological Characterization

Research the spawning characteristics of native fisheries (redband trout and Kokanee salmon). Conduct a habitat analysis to determine barriers to fish movement.  Evaluate macroinvertebrates available for spawning fish.  Evaluate the extent and impact of Beaver activity in the reach. 


            Sub-Task 330                        Hydrologic Analysis

Determine flow data for Ente Creek using Spokane Tribe of Indians and USGS Gage flow data (if available).  If no flow data is available, hydrologic analysis methods will be used to develop flow hydrographs for Ente Creek.  The team must determine the best hydrologic method to apply (e.g., SCS, HEC-HMS, etc.)


Sub-Task 340                        Hydraulic Analysis and Tributary Barrier Analysis

Conduct a hydraulic study using either HEC-RAS or River2D, depending on the available survey data.  These models will be used to analyze hydraulics and sediment transport within Ente Creek.  The resulting output can help determine fish habitat characteristics and potential barriers to fish movement.


Sub-Task 350                        Design Options and Assessment of Design Options

Select several spawning channel design options, assess those design options based on specified criteria (cost, constructability, effectiveness, etc) and weights, and recommend a final design option that satisfy sponsor requirements. 


Sub-Task 360                        Final Design of Ente Creek Spawning Channel

Design a stream channel within the drawdown zone that prevents water loss and maintains complexity and resting areas for migrating spawning fish. This stream channel should also prevent sedimentation within the drawdown zone and account for Beaver activity while providing spawning habitat. This will include a hydrologic, hydraulic, sediment transport, and habitat analysis to produce the final design. 




Task 300 Deliverables

  • Electronic copy of drawings, calculations, data, reports or calculations completed for the project design and to be included in the project report.

The student group will include a budget that details the costs of completing the project design tasks. This budget is not the “engineers estimate” to complete the implementation of the design; it is the costs to perform the engineering tasks and does not include the value of project team personnel hours. This requirement is contained in Task 100, but is highlighted here.
