Morgan Lake, located in La Grande, Oregon, is a picturesque reservoir primarily used for recreation. Completed in 1976, this earth dam structure stands at a height of 23 feet and has a storage capacity of 780 acre-feet. The lake covers a surface area of 75 acres and is fed by Sheep Creek and Deal Canyon, providing a serene setting for outdoor activities like fishing, boating, and picnicking.

Despite its scenic beauty and recreational appeal, Morgan Lake has been designated as having a high hazard potential and a poor condition assessment. This assessment raises concerns about the safety and maintenance of the dam structure. The last inspection in August 2021 highlighted the need for improvements, with a moderate risk assessment rating of 3. It is crucial for local authorities and relevant agencies to address these concerns and implement necessary risk management measures to ensure the safety and longevity of Morgan Lake for future generations to enjoy.

With its close proximity to the city of La Grande and its importance as a local recreation spot, Morgan Lake serves as a valuable water resource in Union County, Oregon. As water resource and climate enthusiasts, it is essential to monitor and support efforts to maintain and enhance the sustainability of this reservoir. By addressing the identified risks and improving the condition of the dam structure, Morgan Lake can continue to be a beloved outdoor destination while safeguarding the surrounding environment and community.
