Conrad Jim dam
Conrad Jim
Conrad Jim is a privately owned dam located in Marshall County, Oklahoma, near the city of Lebanon. Built in 1974, the primary purpose of this earth dam is flood risk reduction along the Little Hauani Creek. Standing at a height of 20 feet and with a hydraulic height of 15 feet, Conrad Jim has a storage capacity of 80 acre-feet and a normal storage level of 50 acre-feet.
With a low hazard potential and a very high risk assessment rating, this dam is regulated, permitted, inspected, and enforced by the Oklahoma Water Resources Board (OWRB). The structure features a controlled spillway, one valve outlet gate, and a stone core foundation on soil. Despite being last inspected in 2010, Conrad Jim is considered to be in "not rated" condition, highlighting the need for further assessment and risk management measures to ensure its continued safety and functionality for flood control purposes.
For water resource and climate enthusiasts, Conrad Jim represents a vital piece of infrastructure in Oklahoma's flood risk reduction strategy. Its location, design, and regulatory oversight by the OWRB make it a key asset in protecting surrounding areas from potential flooding events. As discussions around climate change and water resource management continue to evolve, the maintenance and upkeep of structures like Conrad Jim will be essential in safeguarding communities and ecosystems against the impacts of extreme weather events.

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 Conrad Jim
Where does the data for Conrad Jim 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.
