St. Mary Land & Exploration Co. dam
St. Mary Land & Exploration Co.
St. Mary Land & Exploration Co. is a privately owned water supply dam located in Wardville, Oklahoma. Managed by the USDA NRCS, the dam is regulated by the Oklahoma Water Resources Board and has a low hazard potential. The dam is designed as a buttress structure with a height of 17.2 feet and a hydraulic height of 15 feet, serving its primary purpose of water supply for the surrounding area.
With a storage capacity of 297.75 acre-feet and a surface area of 28.74 acres, the dam on a tributary to Coal Creek plays a crucial role in water management in Atoka County. Although the dam's condition assessment is not rated, it meets inspection requirements every 5 years and has a very high risk assessment rating. Despite its low hazard potential, the dam's strategic location and function make it a vital resource for water resource and climate enthusiasts interested in sustainable water supply infrastructure in Oklahoma.
Overall, St. Mary Land & Exploration Co. serves as a key water supply structure in Atoka County, contributing to the state's water management efforts. With its controlled spillway and low hazard potential, the dam provides essential water storage capacity for the region. As climate change continues to impact water resources, understanding and maintaining infrastructure like St. Mary Land & Exploration Co. will be critical for ensuring a reliable and sustainable water supply for future generations.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About St. Mary Land & Exploration Co.
Where does the data for St. Mary Land & Exploration Co. 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.
