Summary
Constructed in 1958, this earth dam stands at a height of 15 feet and spans a length of 940 feet. With a primary purpose of providing fire protection and serving as a stock or small fish pond, Thorton No 3 also offers recreational opportunities for the community.
Despite its low hazard potential, Thorton No 3 has not been rated for its condition assessment and lacks updated emergency action plans. However, this dam provides a storage capacity of 126 acre-feet and a maximum discharge of 23 cubic feet per second. While it is not under state jurisdiction or regulation, Thorton No 3 continues to serve its intended purposes and remains a valuable resource for water management in the area.
As a key feature in the local water infrastructure, Thorton No 3 plays a vital role in ensuring fire protection, supporting livestock and fish populations, and offering recreational activities. While improvements in emergency preparedness and condition assessment are necessary, this dam stands as a testament to the importance of private ownership in water resource management and climate resilience efforts.

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.
