Summary

Owned privately, the dam stands at a height of 25 feet and has a length of 248 feet, providing a storage capacity of 27 acre-feet. The dam, designed by USDA NRCS, is classified as an Earth dam with a Buttress core type and is not regulated by the state.

This dam plays a crucial role in fire protection, stock maintenance, and recreation activities in the area. While it does not have a spillway, it is equipped with one outlet gate. The risk assessment for the dam indicates a high risk level, but its condition assessment is currently not rated. With a drainage area of 0.55 square miles, this dam contributes significantly to the local water resource management and wildlife conservation efforts in the region.

Overall, R Windham Dam No 1 stands as a testament to the collaborative efforts of private ownership and government design expertise in creating a sustainable water management infrastructure. Its presence not only enhances the local ecosystem but also provides essential services for the community. As water resource and climate enthusiasts, it is important to monitor and support initiatives like this to ensure the long-term resilience of our natural environment.

Dam Data Reference

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.
