- 1964 Good Friday earthquake changed Eyak Lake water levels when the surrounding area uplifted by approximately 6 feet.
- 1972 sheet pile weir was installed at the outlet of Eyak Lake to re-establish the water surface to pre-earthquake levels and keep nearshore sockeye spawning beds submerged.
- The contract to build the weir was awarded by a State department that no longer exists: the Division of Waters and Harbors.
- 1978 rip-rap installed on the downstream side of the weir to support the structure in response to undercutting.

CRWP has convened a great group of partners from 13 organizations to actualize and implement this important project:
- Cordova Electric Cooperative
- City of Cordova
- Native Village of Eyak
- PWS Science Center
- The Eyak Corporation
To move this project forward, we completed the following in 2021:
- Hired an engineer to complete a site survey, geotechnical investigations, and develop concepts for the community to consider. Read the Eyak Lake Weir Alternatives Analysis here. The preferred alternative is concept 3: Replace in-kind with natural fishway (Pg. 9);
- Conducted a community survey that had 95 respondents (Thanks!). Survey results are included in the report above.
- Hosted a workshop with engineers in July to learn more about alternatives. View google slides from presentation here.
- **To watch a complete recording of the Public Workshop, see the Youtube video below.**
- Submitted funding proposal to Exxon Valdez Oil Spill Trustee Council and received $5.7 million for complete design and construction of a new outlet structure.
- With the funding official in 2022, CRWP is currently convening stakeholders to work on finalizing the design in 2023.
- Opportunities for Community Inputs: Stay tuned for upcoming opportunities and as always, please feel free to reach out at any time with thoughts, history, or comments on the Eyak Lake weir structure.
