State Stock #7 dam
State Stock #7
State Stock #7, located in Cheyenne, Colorado, is a privately owned earth dam completed in 1939 primarily used for fire protection, stock, and small fish pond purposes. With a height of 18 feet and a length of 500 feet, this dam has a storage capacity of 140 acre-feet and covers a surface area of 15 acres. Despite its low hazard potential, it has been identified as having a high risk level, prompting the need for risk management measures to be put in place.
Managed by the Colorado Department of Water Resources, State Stock #7 is regulated, permitted, inspected, and enforced by state authorities. The dam is situated on Maverick Creek-TR and falls under the jurisdiction of the Kansas City District. Although it has not been rated for its condition, the last inspection took place in October 1987. The absence of spillways and locks indicates a simpler structure, but its risk assessment suggests the importance of monitoring and implementing safety protocols.
For water resource and climate enthusiasts, State Stock #7 presents an intriguing case study of a historic dam in Colorado with a blend of purposes including fire protection and stock maintenance. The intersection of private ownership, state regulation, and the need for risk management highlights the complexities involved in maintaining aging infrastructure while ensuring public safety and environmental protection. As climate change impacts water resources, understanding the condition and risk level of structures like State Stock #7 becomes crucial for sustainable water management practices.

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.
- 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.
- 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.
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, environmental 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.

About State Stock #7
Where does the data for State Stock #7 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
