Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
