Summary
1, located in Johnson County, Wyoming, is a privately owned earth dam built in 1913 primarily for irrigation purposes along the Little North Fork Crazy Woman River. Standing at a height of 37 feet with a length of 700 feet, this dam has a storage capacity of 327 acre-feet and serves as a crucial water source for agricultural activities in the area. Despite its age, the dam is regulated, inspected, and enforced by the Wyoming State Engineer's Office to ensure its structural integrity and safety.
The dam's spillway, designed as uncontrolled with a width of 30 feet, poses a significant hazard potential due to its poor condition assessment. With a moderate risk assessment rating, it is essential for emergency action plans to be developed and maintained to mitigate any potential risks associated with this aging structure. The dam's emergency preparedness measures, including the existence of inundation maps and updated emergency contacts, are crucial in ensuring the safety of downstream communities in the event of a dam failure.
In light of its historical significance and continued importance for irrigation in the region, Kingsbury Todd No. 1 serves as a reminder of the critical role that dams play in water resource management. As water resource and climate enthusiasts, it is essential to monitor and support efforts to maintain and upgrade infrastructure like Kingsbury Todd No. 1 to ensure the sustainable use of water resources for future generations.

Dam Data Reference
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.
