Summary
This dam serves the primary purpose of debris control and flood risk reduction along the NO FORK BLACK VERMILLION RV-TR. With a height of 23.4 feet and a length of 700 feet, Frd No 77 has a storage capacity of 338 acre-feet and covers a surface area of 12 acres, protecting a drainage area of 0.77 square miles.
The dam, regulated by the Kansas Department of Agriculture, is classified as low hazard potential with a moderate risk assessment. It has a spillway width of 40 feet and a maximum discharge capacity of 1274 cubic feet per second. Despite not having outlet gates, Frd No 77 has been serving its purpose effectively, with no reported condition assessment and a history of no modifications since its completion.
Water resource and climate enthusiasts interested in the management and maintenance of dams for flood control and debris management would find Frd No 77 an intriguing case study. This structure, situated in Marshall County, Kansas, highlights the importance of local government ownership and regulatory oversight in ensuring the safety and functionality of critical infrastructure for water resource management in the region.

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.
