Summary
With a height of 25 feet and a length of 450 feet, this dam provides a significant storage capacity of 142 acre-feet for the surrounding area. The dam serves a primary purpose of grade stabilization, helping to prevent erosion and protect the watershed.
Despite its low hazard potential, the dam has not been rated for its condition assessment. However, it is considered to have a moderate risk level, indicating the need for ongoing monitoring and potential risk management measures. With a spillway width of 40 feet and a maximum discharge of 244 cubic feet per second, the dam is designed to handle significant water flow during periods of high precipitation. While the dam does not have outlet gates, it plays a crucial role in managing water resources in the region.
Overall, Bear Creek Watershed Dam F-20 is an essential infrastructure project that contributes to the conservation and management of water resources in the area. With its strategic location and design, the dam helps to protect against erosion, stabilize the grade, and mitigate flood risks along TR-Bear Creek. Continued monitoring and potential risk management measures will be important to ensure the long-term safety and effectiveness of this vital earth dam.

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.
