Summary
This Earth-type dam, completed in 1955, stands at 53 feet high and spans 452 feet in length, with a maximum storage capacity of 310 acre-feet and a normal storage of 250 acre-feet. The dam has a low hazard potential and has not been rated for its condition as of the last inspection in October 2020.
Despite its modest size, Martin Cull plays a crucial role in water management and agricultural practices in the region, providing essential irrigation infrastructure for the surrounding areas. With a moderate risk assessment rating of 3, the dam is subject to regular inspections, with the next one scheduled in six years. While the dam has not been modified over the years, it remains a vital component of the water resource infrastructure in the area, ensuring the efficient distribution of water for agricultural purposes.
Located in the city of Craig, Colorado, Martin Cull is regulated by the state and adheres to permitting, inspection, and enforcement protocols set by the Colorado Division of Water Resources. Its uncontrolled spillway, with a width of 18 feet, helps manage excess water flow during periods of high discharge, further enhancing its safety and functionality. As a significant contributor to local water resource management, Martin Cull stands as a testament to the importance of sustainable water practices in the face of changing climate conditions.

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.
