Summary
Standing at a height of 25 feet, this dam has a storage capacity of 147 acre-feet and covers a surface area of 11 acres. The dam is situated on the TR-Salk Fork Blackwater River and is under the jurisdiction of the Kansas City District.
Despite its small size, Rasse Lake Dam is classified as having a high hazard potential due to its condition being not rated. The dam does not have a spillway and is not regulated or inspected by state authorities. While it may not be a major structure, its importance lies in providing recreational opportunities for locals and visitors to enjoy the scenic beauty of the lake that it creates.
For water resource and climate enthusiasts, Rasse Lake Dam serves as a reminder of the diverse range of dams across the country, each with its own unique characteristics and purposes. Its presence on the TR-Salk Fork Blackwater River adds to the water infrastructure of the region and contributes to the overall landscape and ecosystem. As the dam continues to provide recreational benefits, its management and maintenance will be crucial in ensuring the safety of those who utilize its facilities.

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.
