Summary
7 is a historic earth dam located in Carbon, Wyoming, along Muddy Creek. Built in 1917 for irrigation purposes, this private dam stands at 25 feet high and spans 390 feet in length. With a storage capacity of 182 acre-feet, it plays a crucial role in providing water for agricultural activities in the region.
Despite its age, Marsh and Company No. 7 has been regularly inspected and maintained by the state regulatory agency, SEO. However, the dam is currently assessed to be in poor condition, with a low hazard potential. While it has an uncontrolled spillway with a width of 50 feet, the dam's overall risk assessment is moderate. Emergency preparedness measures for this structure are not clearly defined, highlighting the need for proactive risk management strategies.
As water resources and climate enthusiasts, understanding the significance of structures like Marsh and Company No. 7 is pivotal in ensuring sustainable water management practices. While this dam continues to support irrigation needs in the area, ongoing maintenance and risk assessment efforts are essential to safeguard its functionality and prevent potential hazards. By staying informed and advocating for responsible water infrastructure management, we can contribute to a more resilient and secure water future for communities reliant on structures like Marsh and Company No. 7.

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.
