Summary
Built in 1950 by the tribal government, this dam stands at a height of 17 feet and has a storage capacity of 70 acre-feet. With a spillway width of 1 foot and a controlled spillway type, Sober Bert Jr is designed to handle a maximum discharge of 600 cubic feet per second, making it a crucial structure for water resource management in the area.
Despite being classified as having a low hazard potential, Sober Bert Jr is considered to have a very high risk due to its age and condition assessment not being rated. The dam is equipped with a valve outlet gate and has a designated inspection frequency of 5 years. However, the last inspection was conducted in 2010, raising concerns about the maintenance and safety of this important water infrastructure.
As climate change continues to impact water resources, the risk assessment for Sober Bert Jr becomes even more vital. With its strategic location and role in managing water flow along TR-Deadman Creek, it is essential for the tribal government and relevant agencies to prioritize the inspection, maintenance, and potential upgrades of this dam to ensure the safety and sustainability of the surrounding community and environment.

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.
