Summary
Designed by the USDA NRCS, this earth dam stands at a height of 26 feet and stretches 345 feet in length, with a storage capacity of 57 acre-feet. The dam is situated on TR-BRUSH CR river/stream and has a spillway width of 40 feet, allowing for a maximum discharge of 670 cubic feet per second in case of high water levels.
With a low hazard potential and a moderate risk assessment rating, Tabo Creek Watershed Dam B-20 is currently in a not rated condition assessment status. Despite not being regulated or inspected by the state, the dam continues to fulfill its primary purpose of grade stabilization effectively. The surrounding area benefits from the normal storage capacity of 17 acre-feet, covering a drainage area of 30 square miles and providing flood control measures. As a key feature in the water resource management of the region, this dam plays a vital role in ensuring the safety and sustainability of the local environment.
Although Tabo Creek Watershed Dam B-20 has not been modified over the years and lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP), it remains a reliable structure for water resource management in Lafayette County. With no outlet gates and a stone core foundation on soil, the dam serves as a testament to the importance of proper design and construction in maintaining the integrity of water infrastructure. As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like Tabo Creek Watershed Dam B-20 in protecting communities and natural habitats from potential water-related hazards.

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.
