Summary
Built in 2002, this earth dam stands at a height of 36 feet and has a structural height of 41 feet, with a length of 340 feet and a storage capacity of 77 acre-feet. The primary purpose of this dam is for recreation, providing a surface area of 5.7 acres for activities such as fishing, boating, and wildlife observation.
With a low hazard potential and a moderate risk assessment rating, the Morrison Lake Dam is considered to be in good condition, although its emergency action plan and risk management measures have not been evaluated. The dam is equipped with an uncontrolled spillway and has no outlet gates, making it important for officials to closely monitor its integrity and maintenance. Despite being privately owned, the dam plays a vital role in water resource management in the area, particularly for regulating the flow of Halls Creek.
For water resource and climate enthusiasts, the Morrison Lake Dam serves as a noteworthy example of a privately owned structure with state regulation and oversight. Its construction and operation highlight the importance of maintaining dams for both recreational and water management purposes, while also emphasizing the need for regular inspections and emergency preparedness measures to ensure public safety and environmental protection.

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.
