Summary

Stroh Ec #1, located in Elbert County, Colorado, is a privately owned earth dam completed in 1972 for flood risk reduction along Dry Creek. Standing at 23 feet tall with a hydraulic height matching, it boasts a length of 500 feet and a storage capacity of 90 acre-feet. The dam's spillway, with a width of 120 feet, is uncontrolled, allowing for a maximum discharge of 3100 cubic feet per second.

With a hazard potential rated as low and a satisfactory condition assessment, Donald E. Stroh Ec #1 serves its purpose effectively in managing flood risks in the region. The dam, inspected every 3 years, has a moderate risk assessment rating, signaling a moderate level of potential hazards associated with its operation. The structure is regulated by the Colorado Department of Water Resources, ensuring compliance with state permitting, inspection, and enforcement protocols.

Overall, Donald E. Stroh Ec #1 provides a crucial flood risk reduction function in Elbert County, Colorado, safeguarding the surrounding area from potential water-related disasters. Its strategic location, structural design, and operational efficiency make it a vital component of the region's water resource and climate management infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
