Summary

Built in 1972 by USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 12 feet and a length of 1150 feet, it has a storage capacity of 68 acre-feet and covers a surface area of 4.02 acres. The dam is situated on Plum Creek-TR and is managed by the Kansas City District.

Despite being classified as having a low hazard potential and not yet rated for its condition assessment, 301 plays a crucial role in water resource management in Woodson County, Kansas. With a drainage area of 0.21 square miles and a maximum discharge of 334 cubic feet per second, this dam helps regulate water flow and provides essential water storage for local agricultural and environmental needs. While it does not have a spillway type or outlet gates, 301 remains a vital infrastructure for the community.

As water resource and climate enthusiasts continue to monitor and assess the impact of dams like 301 on local ecosystems and water availability, understanding the design, purpose, and condition of these structures is essential for sustainable water management. With its history of construction by the Natural Resources Conservation Service and its primary focus on fire protection and stock pond usage, 301 stands as a testament to the intersection of human infrastructure and natural resource conservation in the heart of Kansas.

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.
