Cope Et dam
Cope Et
Cope Et, located in Chisney, Oklahoma, is a privately owned earth dam constructed in 1979 by the USDA NRCS. This dam, with a height of 29 feet and a length of 470 feet, serves multiple purposes including flood control on the TR-Little Riv and has a storage capacity of 70 acre-feet. Managed by the OWRB, Cope Et is regulated, permitted, inspected, and enforced to ensure its safety and functionality.
Despite being classified as low hazard potential with a very high risk assessment, Cope Et has not been rated for its condition. It has one valve outlet gate and a controlled spillway with a width of 1 foot. The dam undergoes inspections every 5 years, with the last one conducted in May 2011. While the emergency action plan status and risk management measures are not specified, the dam's risk assessment score indicates a need for heightened vigilance and monitoring by authorities and stakeholders in the region.
As a crucial water resource structure in Pottawatomie County, Cope Et plays a significant role in managing water flow and storage in the area. With its stone core and soil foundation, this dam stands as a testament to collaborative efforts between private owners, federal agencies, and state regulators to ensure the safety and sustainability of water resources in Oklahoma. Climate enthusiasts and water resource professionals alike can appreciate the intricate design and regulatory framework that governs Cope Et for the benefit of the local community and environment.

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 Cope Et
Where does the data for Cope Et 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.
