Summary
Constructed in 1973, this private-owned Earth dam stands at a height of 10 feet and has a storage capacity of 130 acre-feet. With a normal storage level of 63 acre-feet, the reservoir covers an area of 11 acres and is fed by Coal Creek, making it a valuable resource for both wildlife and recreational activities.
Despite its low hazard potential, Theos Reservoir #1 is regulated and inspected by the Colorado Division of Water Resources, ensuring its safety and compliance with state regulations. The dam features an uncontrolled spillway with a width of 5 feet, allowing for a maximum discharge rate of 130 cubic feet per second. Although the condition assessment is currently listed as "Not Rated," the reservoir poses a moderate risk level of 3, highlighting the importance of ongoing risk management measures and emergency preparedness.
With its picturesque setting in Rio Blanco County and proximity to the river, Theos Reservoir #1 offers not only a sanctuary for fish and wildlife but also a peaceful retreat for visitors seeking to immerse themselves in nature. As climate change continues to impact water resources, the significance of maintaining and monitoring such reservoirs for both ecological and recreational purposes cannot be overstated.

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.
