Hadley dam
Hadley
Hadley is a privately owned dam located in Clinton, Oklahoma, along the East Barnitz Creek. Built in 1965, this Earth-type dam stands at 27 feet high and spans a length of 6000 feet, with a storage capacity of 80 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state inspection and enforcement. Despite being classified as having a low hazard potential, the dam is considered to have a very high risk due to its location and potential impact on the surrounding area.
The primary purpose of Hadley Dam is listed as "Other," with a controlled spillway and one outlet valve. The dam is not rated for its condition assessment and has not been updated with emergency action plans or inundation maps. Although it is not under the jurisdiction of any federal agency, Hadley Dam falls within the Tulsa District of the US Army Corps of Engineers. The risk associated with the dam is considered to be very high, emphasizing the importance of ongoing monitoring and maintenance to ensure the safety of the surrounding community and water resources.
Despite its relatively low hazard potential, Hadley Dam in Oklahoma poses a significant risk due to its age, location, and limited risk management measures in place. Climate and water resource enthusiasts will find this structure intriguing for its historical significance, structural characteristics, and the need for enhanced emergency preparedness. With its high-risk classification and state-regulated status, Hadley serves as a reminder of the ongoing challenges in managing and maintaining critical infrastructure in the face of changing environmental conditions.

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 Hadley
Where does the data for Hadley 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.
