Prison dam
Prison
Prison is a state-regulated dam located in Pittsburg, Oklahoma, with a primary purpose classified as "Other". Completed in 1930, this earth dam stands at a height of 28 feet and has a hydraulic height of 24 feet, with a length of 3000 feet. The dam has a normal storage capacity of 435 acre-feet and a maximum storage capacity of 508 acre-feet, with a surface area of 55 acres. The dam is situated on the TR-SANDY CR river or stream, within the Tulsa District of Oklahoma.
The dam is equipped with a controlled spillway and a single valve outlet gate. Despite being classified as having a low hazard potential, the risk assessment for Prison is categorized as "Very High (1)". The dam has not been rated for its condition assessment, with the last inspection conducted in May 2011. It is important to note that the dam is not owned or funded by any federal agency, and the state regulatory agency overseeing its operation is the Oklahoma Water Resources Board (OWRB).
With its unique design features and risk assessment indicating a high level of potential hazard, Prison serves as a point of interest for water resource and climate enthusiasts. The dam's location in the scenic CHRISTIAN HILL CEM area of Pittsburg, Oklahoma, coupled with its historical significance dating back to the early 20th century, makes it a noteworthy structure to study and monitor. As a state-regulated dam, it plays a crucial role in water management and flood control efforts within the region, highlighting the importance of maintaining and assessing its condition for long-term sustainability.

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 Prison
Where does the data for Prison 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.
