Orendorf Ch Jr dam
Orendorf Ch Jr
Orendorf Ch Jr is a privately owned earth dam located in Hanson, Oklahoma, within Sequoyah County. Built in 1930, this structure stands at a height of 15 feet and has a maximum storage capacity of 50 acre-feet. The dam, which spans 450 feet in length, serves as a crucial element for water resource management in the area, particularly for the TR-WOLF CREEK river or stream.
Managed by the Oklahoma Water Resources Board, Orendorf Ch Jr has a controlled spillway and is equipped with a single valve outlet gate. Despite its low hazard potential and current "Not Rated" condition assessment, the dam presents a very high risk due to its age and potential vulnerabilities. Regular inspections are carried out every 5 years to ensure the structural integrity and safety of the dam, with the last inspection conducted in December 2010.
For water resource and climate enthusiasts, Orendorf Ch Jr provides a fascinating case study on the importance of maintaining aging infrastructure for effective water management. With its historical significance and critical role in the local ecosystem, this dam serves as a reminder of the ongoing challenges faced in balancing water resource needs with environmental and safety considerations in the face of climate change and evolving regulatory standards.

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 Orendorf Ch Jr
Where does the data for Orendorf Ch Jr 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.
