Summary
The dam, with a height of 25 feet, primarily serves as a recreational area with a normal storage capacity of 35 acre-feet and a maximum storage capacity of 70 acre-feet. The dam's spillway type is controlled, with a width of 1 foot, and it has one valve as an outlet gate.
Although De Coe has a low hazard potential, it is classified as having a very high risk due to its condition assessment being not rated. The last inspection of the dam was in November 2000, and it is scheduled for inspections every 5 years. The risk management measures for the dam are currently not specified, and there is no Emergency Action Plan (EAP) in place for potential incidents.
Climate and water resource enthusiasts may find De Coe to be an interesting case study in dam management and risk assessment. The dam's location in a high-risk area highlights the importance of regular inspections and the need for a comprehensive EAP to mitigate potential hazards. Additionally, the dam's role in providing recreational opportunities underscores the complex balance between water resource management and public safety.

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.
