Summary

Completed in 2003, this dam serves primarily for irrigation purposes, with a storage capacity of 110 acre-feet and a surface area of 5.66 acres. The dam stands at a height of 26 feet, with a hydraulic height of 23 feet, and a length of 2450 feet.

The dam's spillway type is uncontrolled, with a width of 4 feet, and it has a low hazard potential with a fair condition assessment as of the last inspection in March 2020. Despite its low hazard potential, the dam is subject to state regulation and inspection by the Wyoming State Engineer's Office. The risk assessment for Pilch 14-2 Pit is moderate, with no emergency action plan prepared at the time of data update in March 2022.

Overall, Pilch 14-2 Pit represents an important water resource infrastructure for irrigation in the region, with a moderate risk assessment level. The dam's location in a rural area and its relatively low hazard potential highlight the importance of ongoing monitoring and maintenance to ensure its continued safe operation for the surrounding community and environment.

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.
