Summary
1 is an earth dam constructed in 1970 by the USDA NRCS with a primary purpose of flood risk reduction along the Little Dry Creek. Standing at 27 feet high with a hydraulic height of 28 feet, this dam has a storage capacity of 140 acre-feet and a normal storage capacity of 85 acre-feet. With a satisfactory condition assessment and low hazard potential, Russell No. 1 plays a crucial role in managing water resources and mitigating flood risks in the region.
Managed by a private owner, this dam is regulated by the Colorado Department of Water Resources and undergoes regular inspections to ensure its structural integrity and operational efficiency. The dam features an uncontrolled spillway type with a width of 70 feet, capable of handling a maximum discharge of 1600 cubic feet per second. Despite its moderate risk assessment, Russell No. 1 has been deemed to meet guidelines for emergency action plans, although detailed inundation maps and risk management measures are yet to be fully documented.
In the heart of Bennett, Colorado, Russell No. 1 stands as a testament to effective water resource management and climate resilience. With a strategic location and a history of successful flood risk reduction, this dam serves as a vital infrastructure supporting the community's safety and water security. As water resource and climate enthusiasts, the intricate details of Russell No. 1's design, operation, and regulatory oversight present a fascinating case study on the intersection of engineering, environmental protection, and emergency preparedness in safeguarding our water resources for a sustainable future.

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.
