Summary

2 is a private irrigation dam located in Johnson County, Wyoming, along the Little North Fork Crazy Woman River. Built in 1917, this earth dam stands at a height of 32 feet and has a hydraulic height of 29 feet, providing a storage capacity of 706 acre-feet. The dam spans a length of 1240 feet and covers a surface area of 44 acres, serving the primary purpose of irrigation for the surrounding area.

Despite its historical significance, Kingsbury Todd No. 2 is facing challenges in terms of its condition assessment, which has been rated as poor. The dam has a significant hazard potential, leading to a moderate risk assessment of 3. With the last inspection conducted in April 2019, it is crucial to address the maintenance and safety concerns to ensure the continued functionality and safety of the structure.

As water resource and climate enthusiasts, understanding the significance of maintaining and managing dams like Kingsbury Todd No. 2 is essential for sustainable water management practices. With its location in a critical watershed area, the dam plays a vital role in supporting agricultural activities and water supply in the region. It is important to prioritize the necessary upgrades and maintenance to mitigate risks and ensure the long-term resilience of this infrastructure.

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.
