Summary
Built in 2003 by the USDA NRCS, this dam on the Canadian Sandy River serves a variety of purposes and stands at an impressive height of 71.15 feet with a hydraulic height of 27.3 feet. With a low hazard potential and a very high risk assessment rating, this dam is closely monitored and inspected regularly to ensure its structural integrity.
The dam has a storage capacity of 71.15 acre-feet and covers a surface area of 7.8 acres, providing essential water resources for the surrounding area. Its spillway, controlled by a 1-foot wide structure, helps regulate water flow and prevent flooding during periods of heavy rainfall. Despite its high risk assessment, the dam's condition assessment is currently listed as "Not Rated", indicating a need for further evaluation to ensure the safety of the structure.
Overall, Oknoname 30170 is a crucial piece of infrastructure in the region, providing water storage and flood control for the community of Roff. With its unique design and purpose, this dam highlights the importance of proper regulation and maintenance in ensuring the safety and efficiency of our water resources in the face of changing climate patterns.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
