City of Calgary Project Note: Inglewood Bird Sanctuary Fish Habitat and Erosion Mitigation Project Update
Below is a note my office received from the Water Resources river engineering group. Have a read and please share it with others in Inglewood, or who might otherwise be interested in it.

The Inglewood Bird Sanctuary has been one of the Cities most ecologically important parks for nearly 90 years. Unfortunately, due to its age, some of the hydraulic structures that control the water level in the lagoon have passed their useful life and are putting the park’s lagoon at risk.
As part of the Bend in the Bow review process, the concept of reconnecting the lagoon to the river was suggested to improve water quality, reduce water level fluctuations in the lagoon as well as improve fish habitat.
This project involves rehabilitating the two original hydraulic control structures and reconnecting a small flow through the lagoon year round. The project is currently in the preliminary design phase and will undergo an exhaustive environmental assessment to
ensure none of the wildlife that use this park will be negatively impacted by the proposed changes.
As part of the design work and environmental assessments you may see increased activity of scientists and engineers in the park. They’re on site to help ensure this important work will be done in the best manner possible. We hope this does not impact your enjoyment of
the park and thank you for your understanding.
This project is currently expected to begin construction in the winter of 2020 at the earliest. This is due to the amount of time needed to obtain regulatory approvals to do this work and because construction within the river and park is only allowed during certain timeframes in order to ensure bird nesting and fish spawning is not disturbed.
The project site is located in and around the lagoon in the Inglewood Bird Sanctuary (Street address: 2425 9 Ave SE) Work will entail:
- Reconnection of the lagoon to the Bow River to provide continuous flows into the lagoon, which is similar to the conditions at Prince’s Island Park lagoon.
- Replacing and strengthening the two outlet structures and providing a more defined channel out of the lagoon at the downstream end.
- Habitat enhancement components including large wood features which will provide habitat for both birds and fish.
- Work on the gravel bars upstream and around the sanctuary will also be necessary to ensure the project’s functions well in the long term.
