Oak-Middle 66-A dam
Oak-Middle 66-A
Oak-Middle 66-A is a local government-owned earth dam in Nebraska, designed by the USDA NRCS and regulated by the NE DNR. This dam, completed in 1983, stands at a height of 30 feet and serves primarily for flood risk reduction purposes. With a storage capacity of 428 acre-feet and a drainage area of 1.6 square miles, Oak-Middle 66-A plays a vital role in managing water flow and reducing the risk of flooding in the area.
Located in Butler County, Nebraska, near the TR-OAK CREEK, Oak-Middle 66-A has a low hazard potential and is currently in satisfactory condition as per the last inspection conducted in March 2016. The dam has a structural height of 30 feet and a hydraulic height of 28 feet, with a maximum discharge capacity of 467 cubic feet per second. Despite its simple design of stone core and soil foundation, Oak-Middle 66-A has proven to be effective in mitigating flood risks and protecting the surrounding community.
With its strategic location and significant contribution to flood risk reduction, Oak-Middle 66-A stands as a key infrastructure managed by the local government in partnership with federal agencies like the USDA NRCS. As climate change impacts continue to pose challenges to water resources management, dams like Oak-Middle 66-A play a crucial role in safeguarding communities and ecosystems against the increasing threats of extreme weather events and flooding.

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 66-A
Where does the data for Oak-Middle 66-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.
