Summary
Constructed in 1993, this earth dam stands at 30 feet high with a hydraulic height of 27 feet, providing a storage capacity of 24 acre-feet. With a surface area of 2 acres and a drainage area of 0.52 square miles, the dam plays a crucial role in mitigating flood risks and managing water resources in the region.
Managed by a private owner, the Enlargement of The 29-35-4 has been deemed to have a low hazard potential and fair condition assessment. Despite its modest size, the dam's spillway width of 5 feet allows for a maximum discharge of 102 cubic feet per second. The structure is regulated and inspected by the SEO, ensuring its compliance with state permitting and enforcement regulations for continued safe operation.
With Liz Cheney (R) representing the Congressional District of Wyoming, the Enlargement of The 29-35-4 stands as a testament to effective water resource management and climate resilience in the region. Its moderate risk assessment rating underscores the importance of maintaining and monitoring this crucial infrastructure to safeguard against potential hazards and preserve the surrounding ecosystem for future generations of water resource and climate enthusiasts.

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.
