Shadwick dam
Shadwick
Shadwick, a privately owned dam located in Le Flore, Oklahoma, on Coal Creek, was completed in 1967 and serves a primary purpose of "Other." Standing at a height of 21 feet, with a dam length of 500 feet, Shadwick has a NID storage capacity of 630 acre-feet and a normal storage capacity of 330 acre-feet. The dam has a controlled spillway type with a width of 2 feet and is equipped with a single valve outlet gate. Despite its low hazard potential, Shadwick has a very high risk assessment rating, emphasizing the importance of ongoing monitoring and maintenance.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and falls under state jurisdiction for permitting, inspection, and enforcement. The last inspection of Shadwick took place in December 2010, with an inspection frequency of 5 years. The condition assessment of the dam is currently listed as "Not Rated," highlighting the need for further evaluation to ensure its structural integrity and safety. While the dam has not been modified in recent years, its risk management measures and emergency preparedness plans are not clearly defined, indicating a potential area for improvement in ensuring the safety of the surrounding community and environment.
Overall, Shadwick stands as a critical infrastructure component in the water resource management of Le Flore County, Oklahoma. With its strategic location on Coal Creek and significant storage capacity, ongoing monitoring and maintenance efforts are essential to mitigate the very high risk assessment associated with the dam. Collaboration between the private owner, state regulatory agencies, and local stakeholders will be crucial in implementing effective risk management measures and emergency response plans to safeguard against potential hazards and ensure the long-term sustainability of this vital water resource infrastructure.

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 Shadwick
Where does the data for Shadwick 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.
