About this dam

Tapley John

Tapley John, located in McCurtain, Oklahoma, is a privately owned dam that serves multiple purposes, including water resource management. Built in 1950, this earth dam stands at a height of 21 feet and has a maximum storage capacity of 90 acre-feet. The dam, situated on TR-MUD CR river, has a controlled spillway and a low hazard potential.

Despite being a privately owned structure, Tapley John is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure safety and compliance. The dam is equipped with a single valve outlet gate and has a very high risk assessment rating, indicating the importance of effective risk management measures. With a surface area of 10 acres and a drainage area not specified, Tapley John plays a crucial role in the local water infrastructure.

In the event of an emergency, Tapley John has a designated emergency action plan (EAP) in place, though details about its preparation and adherence to guidelines are not provided. The dam's condition assessment is listed as "Not Rated," suggesting a need for further evaluation. With a history dating back to the mid-20th century and a congressional representative in the form of Markwayne Mullin (R), Tapley John remains a significant water resource structure in the region, warranting continued monitoring and maintenance.

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.

FAQ

About Tapley John

Where does the data for Tapley John 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.
