Summary
This dam stands at a height of 29 feet, with a hydraulic height of 28 feet and a structural height of 30 feet. It stretches 480 feet in length and has a storage capacity of 27 acre-feet, serving a drainage area of 3000 acres.
Despite its low hazard potential, York Twp Site Ca-170-3 is categorized as having a high risk level (2) based on data analysis. The dam, made primarily of earth with a stone core and soil foundation, has not been rated for its condition assessment. With no spillway and outlet gates, the dam's emergency action plan status, inundation maps, and risk management measures are not clearly defined, posing potential challenges in case of an emergency situation.
For water resource and climate enthusiasts, York Twp Site Ca-170-3 represents an essential infrastructure for grade stabilization along TR-MEDICINE CREEK in Missouri. However, there are notable gaps in the dam's emergency preparedness and risk management aspects, which warrant further attention to ensure the safety and resilience of the structure in the face of potential hazards.

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.
