Year 2 Study Reports and Phase 1 Engineering

This section contains the draft year 2 study reports that were distributed in March 2023 for review and comment, all the comments received on the draft year 2 study reports, and the final year 2 study reports dated June 2023.

This section also contains the presentations that were given to the Technical Work Groups in March 2023 to provide an overview of the year 2 study results

Preliminary Study Results and Engineering Assesment

Some preliminary instream flow and geomorphology modeling results, as well as some preliminary lake fisheries and water quality study results, were presented to the Aquatics Technical Work Group (TWG) during a series of meetings in late 2022. At these meetings, the project team also presented ideas for potential engineering solutions that would provide flows into the Eklutna River and fish passage into Eklutna Lake. This section contains those presentations, draft tech memos, comments, responses, and final tech memos.

This section also contains the Memorandums of Agreement (MOAs) executed with the parties to the 1991 Agreement to address specific legal concerns regarding the 2021 study flow releases, as well as the final downramping procedures and public safety plan.

2020 Study Efforts

The project owners conducted some early study efforts in 2020 in order to support the overall study planning process. This included collecting LiDAR data, aerial imagery, and spherical video of the Eklutna River and Eklutna Lake, inspecting the spillway and drainage outlet gate, establishing some geomorphology transects and installing some scour monitors in the Eklutna River. This section contains the reports associated with those study efforts.
