Oak-Middle 67-A dam
Oak-Middle 67-A
Oak-Middle 67-A is a vital structure located in Butler, Nebraska, designed by the USDA NRCS to serve the purpose of flood risk reduction. This earth dam, completed in 1958, stands at a height of 40 feet with a hydraulic height of 40 feet and a structural height of 41 feet. It spans 670 feet in length, providing a storage capacity of 279 acre-feet and a maximum discharge of 4590 cubic feet per second. Despite its low hazard potential, Oak-Middle 67-A is regulated and inspected by the Nebraska Department of Natural Resources, ensuring its satisfactory condition and the safety of the surrounding area.
Managed by the local government, Oak-Middle 67-A plays a crucial role in mitigating flood risks along TR-OAK CREEK in Nebraska. The dam's normal storage capacity of 54.5 acre-feet covers a surface area of 7.6 acres within a drainage area of 0.9 square miles. With its foundation on soil and core made of stone, this structure exemplifies responsible water resource management and climate resilience. While it has not undergone recent modifications, Oak-Middle 67-A is subject to regular inspections every five years, with the last assessment conducted in March 2016, affirming its satisfactory condition.
Situated in RAYMOND, Nebraska, Oak-Middle 67-A stands as a testament to effective collaboration between the Natural Resources Conservation Service and local authorities in enhancing flood protection measures. With Congressman Jeff Fortenberry representing the area, this dam underscores the importance of infrastructure in safeguarding communities against natural disasters. As an integral component of the Kansas City District, Oak-Middle 67-A showcases the commitment to sustainable water management practices and the preservation of water resources 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.

About Oak-Middle 67-A
Where does the data for Oak-Middle 67-A 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.
