Summary
Completed in 1978, the dam stands at a height of 19 feet, with a storage capacity of 91 acre-feet. The dam is situated on the TR-Goodwater Creek, with a drainage area of 65 square miles.
Despite its critical role in providing water for irrigation, Cook Lake Dam has a high hazard potential and has not been rated for its condition assessment. The dam does not fall under state regulation or inspection, posing potential risks to the surrounding area in case of a failure. It is crucial for water resource and climate enthusiasts to monitor and ensure the safety of such infrastructure to prevent any potential disasters.
As a significant water resource in the area, Cook Lake Dam serves as a reminder of the importance of proper maintenance and oversight of dams for both agricultural and environmental purposes. Climate enthusiasts should advocate for regular inspections and risk assessments to safeguard against any potential hazards that may arise from aging infrastructure like Cook Lake Dam.

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.
