Summary

Built in 1969 by the USDA NRCS, this earth dam stands at a height of 25 feet and has a hydraulic height of 22 feet. With a normal storage capacity of 14 acre-feet and a maximum storage of 195 acre-feet, Frd No 25 plays a crucial role in managing water resources in the Plum Creek-TR watershed.

Despite being classified as having a low hazard potential, Frd No 25 is considered to have moderate risk with a risk assessment rating of 3. The dam features an uncontrolled spillway with a width of 40 feet and serves the primary purpose of flood risk reduction. Located in the city of Douglass, Kansas, this structure covers a surface area of 4.74 acres and has a drainage area of 0.54 square miles. While it is not regulated by the state and does not have a state inspection or enforcement agency, Frd No 25 continues to be a vital component of the water management infrastructure in the area.

With its buttress core type and earth dam construction, Frd No 25 is an essential component of the flood control system in the region. While it has not been rated for condition assessment and does not have an emergency action plan in place, this dam remains a key player in mitigating flood risks and ensuring the safety of residents in the surrounding areas. As water resource and climate enthusiasts, understanding the importance of structures like Frd No 25 can provide valuable insights into the management of water resources and the impact of climate on 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.
