Summary

Built in 1973 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the North Fork Black Vermillion River. With a height of 23 feet and a length of 820 feet, Frd No 84 has a storage capacity of 113.17 acre-feet and covers a surface area of 4.73 acres.

Despite being classified as having a low hazard potential, Frd No 84 is subject to moderate risk based on a rating of 3. The dam features an uncontrolled spillway with a width of 40 feet and does not have outlet gates. While its condition assessment is not rated and inspection frequency is listed as 0, there is no state regulation or permitting associated with this structure. The dam's risk management measures, emergency action plan status, and inundation maps preparedness are all marked as unknown, highlighting areas for potential improvement in the future.

Water resource and climate enthusiasts interested in Frd No 84 will find a structurally sound earth dam that plays a crucial role in mitigating flood risks in the region. With its location in Marshall County, Kansas, this dam underscores the importance of proactive risk management and emergency preparedness for ensuring the safety and resilience of water infrastructure in the face of changing environmental conditions.

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.
