Summary
With a height of 33 feet and a storage capacity of 300 acre-feet, this earth dam plays a crucial role in ensuring a steady water supply for the community. Despite being classified as having a low hazard potential and not currently rated for its condition, the dam remains an essential infrastructure for water resource management in the region.
Situated on the TR East Fork Sni-A-Bar Creek, the Odessa Old Reservoir Dam is owned by the local government and falls under the jurisdiction of the Kansas City District. This dam, with its buttress core type and unlisted foundation, covers a surface area of 17 acres and has a drainage area of 1530 acres. Although lacking inspection frequency data and emergency preparedness assessments, the dam continues to fulfill its primary purpose of water supply with a normal storage capacity of 185 acre-feet. For water resource and climate enthusiasts, the Odessa Old Reservoir Dam stands as a testament to the importance of infrastructure in managing and sustaining water resources for communities.

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.
