Summary

1 is a privately owned dam located in Sublette, Wyoming, along the Boelte Draw river. Built in 2003 by Rio Verde Eng., this earth dam serves as a Fish and Wildlife Pond, providing a habitat for local wildlife. The dam stands at 32 feet high, with a hydraulic height of 18 feet and a length of 416 feet, offering a storage capacity of 93 acre-feet and a surface area of 8.82 acres.

Despite being classified as low hazard potential, Boelte No. 1 is regularly inspected by the Wyoming State Engineer's Office to ensure its fair condition and operational safety. With a moderate risk assessment of "3," the dam is equipped with an uncontrolled spillway, one other controlled outlet gate, and a maximum discharge capacity of 390 cubic feet per second. The dam's main purpose is to support fish and wildlife conservation efforts in the area, contributing to the local ecosystem's sustainability and biodiversity.

Located in a picturesque natural setting, Boelte No. 1 is an essential component of water resource management in the region. Its strategic design and regular maintenance ensure the preservation of the surrounding environment and the safety of the community. As climate and water resource enthusiasts, the details of Boelte No. 1's construction, purpose, and operation offer valuable insights into the intricate balance between human infrastructure and ecological conservation.

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. 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

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, 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.
