Summary

This private earth dam, standing at 25 feet high, has a storage capacity of 54 acre-feet and covers a surface area of 4 acres. Despite being categorized as having a low hazard potential, the dam's condition assessment is currently listed as 'Not Rated', indicating a need for further evaluation and maintenance.

Situated on TR-SNI-A-BAR CREEK and managed by the Kansas City District of the US Army Corps of Engineers, Country Store House Lake Dam primarily caters to recreational purposes. With no state jurisdiction or regulation, the dam is not subject to regular inspections or enforcement measures. Despite its remote location in Grove, Missouri, this dam plays a crucial role in providing water storage and outdoor activities for local residents and visitors alike. As a site of natural beauty and potential risk, continuous monitoring and management of Country Store House Lake Dam are essential for sustainable water resource utilization.

The dam's proximity to a major drainage area of 160 square miles underscores its importance in managing water flow and storage during periods of high discharge. With a storage capacity of 54 acre-feet and a normal storage level of 40 acre-feet, the dam serves as a vital component in the local water infrastructure. While its current condition assessment remains 'Not Rated', efforts to conduct regular inspections, emergency action planning, and risk assessments are crucial in ensuring the long-term safety and functionality of Country Store House Lake Dam for both recreational and water resource purposes.

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.
