About this dam

Scs-Jack Creek Site-2b

SCS-Jack Creek Site-2b in Cookietown, Oklahoma, is a state-regulated earth dam built in 1975 by the USDA NRCS for flood risk reduction along TR-East Jack Creek. Standing at 24 feet tall with a hydraulic height of 21 feet and a length of 1140 feet, this dam provides a maximum storage capacity of 429 acre-feet and normal storage of 128 acre-feet. The controlled spillway, outlet gate, and stone core foundation ensure its structural integrity for managing a maximum discharge of 2050 cfs.

The dam's hazard potential is rated as low, with a very high risk assessment of 1, indicating the importance of ongoing inspection and maintenance. While its condition assessment is not rated, the dam has not been modified since its construction. Despite the last inspection date being in 1980, the state regulatory agency, OWRB, oversees its permitting, inspection, and enforcement. The dam's emergency action plan status, inundation maps, and risk management measures are not documented, highlighting the need for updated protocols to ensure public safety and efficient water resource management.

Located in Tillman County, Oklahoma, SCS-Jack Creek Site-2b plays a vital role in safeguarding the local community from flooding events. With a notable association with the Natural Resources Conservation Service and a primary purpose of flood risk reduction, this earth dam serves as a crucial infrastructure for water resource and climate enthusiasts to study and monitor. As climate change impacts become more pronounced, ensuring the resilience and reliability of such structures is paramount for sustainable water management in the region.

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.
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.
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.

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, environmental 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.

FAQ

About Scs-Jack Creek Site-2b

Where does the data for Scs-Jack Creek Site-2b come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Low hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
