Jackson J.E. Jr. dam
Jackson J.E. Jr.
Jackson J.E. Jr. is a privately owned dam located in Loco, Stephens County, Oklahoma. Built in 1970, this earth dam stands at 17 feet high and has a hydraulic height of 14 feet, with a total length of 800 feet. It serves as a crucial structure on TR Pine Creek, providing a storage capacity of 84 acre-feet. Despite its low hazard potential, it is regulated and inspected by the Oklahoma Water Resources Board to ensure its safety and integrity.
With a normal storage capacity of 69 acre-feet and a surface area of 11 acres, Jackson J.E. Jr. plays a vital role in water resource management in the region. It features a controlled spillway with a width of 1 foot and a valve outlet gate. The dam is designed to handle a maximum discharge of 725 cubic feet per second, offering flood protection to the surrounding area. In case of emergencies, the dam has an established inspection frequency of 5 years to assess its condition and risk potential.
Managed by a private entity, Jackson J.E. Jr. serves as a key infrastructure for water supply, irrigation, and flood control in the region. With its very high risk assessment rating, the dam is subject to strict regulatory oversight and enforcement by the Oklahoma Water Resources Board to ensure public safety and the integrity of the structure. As a significant component of the local water resource infrastructure, Jackson J.E. Jr. underscores the importance of effective dam management and maintenance in the face of changing climate patterns and water resource challenges.

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.

About Jackson J.E. Jr.
Where does the data for Jackson J.E. Jr. 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.
