Summary
Built in 1960 by the USDA NRCS, this dam stands at a height of 28 feet and has a hydraulic height of 24 feet. It serves various purposes, with a primary purpose classified as 'Other'. The dam has a storage capacity of 51 acre-feet and a maximum discharge of 562 cubic feet per second.
Despite being categorized as having a low hazard potential, Selman No.29 is considered to have a very high risk level, with a risk assessment rating of 1. The dam's condition assessment is listed as 'Not Rated', with the last inspection conducted in 2011. It is equipped with a controlled spillway and one outlet valve. The dam is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement.
Selman No.29 plays a crucial role in managing water resources in the region, specifically for the Sleeping Bear Creek. With its strategic location and design, this dam serves as an essential infrastructure for water control and conservation efforts in Oklahoma. For water resource and climate enthusiasts, Selman No.29 presents an intriguing case study in dam engineering and management within the state regulatory framework.

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.
