Summary

This earth dam stands at a height of 23 feet, with a hydraulic height of 23 feet and a structural height of 25 feet, providing storage for 94 acre-feet of water. With a normal storage capacity of 17 acre-feet and a maximum discharge of 480 cubic feet per second, this dam plays a crucial role in managing water resources in the region.

Despite being classified as having a low hazard potential, this dam on TR-BRUSH CR has a moderate risk rating of 3. It features an uncontrolled spillway with a width of 60 feet and is primarily constructed with stone core and soil foundation materials. The dam spans 515 feet in length and covers a surface area of 4 acres, with a drainage area of 110 acres. Although not currently rated for condition assessment, the Tabo Creek Watershed Dam B-29 remains a key infrastructure for water resource management in the city of NORBORNE.

As water resource and climate enthusiasts, the Tabo Creek Watershed Dam B-29 presents an intriguing case study in dam engineering and management. With its historical significance dating back to the 1960s and its ongoing role in grade stabilization, this earth dam serves as a symbol of how human interventions can positively impact the natural environment. As we continue to monitor and assess the condition of this dam, we are reminded of the delicate balance between harnessing water resources for human benefit while safeguarding against potential risks and hazards.

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.
