Oak-Middle 82-B (Modified) dam
Oak-Middle 82-B (Modified)
Oak-Middle 82-B (Modified) is a crucial water resource project located in Seward, Nebraska, designed by the USDA NRCS with a primary purpose of flood risk reduction. This earth dam, completed in 1963, stands at a height of 35.4 feet and has a structural height of 45.1 feet, providing essential protection for the surrounding area against potential flooding events. With a high hazard potential but a satisfactory condition assessment as of June 2020, this dam plays a significant role in managing water flow and storage in the region.
Owned by the local government and regulated by the Nebraska Department of Natural Resources, Oak-Middle 82-B (Modified) serves as a vital infrastructure for flood control in the area. With a normal storage capacity of 32.4 acre-feet and a maximum storage of 371.4 acre-feet, this structure plays a crucial role in managing water levels and ensuring the safety of the community. The dam's location on TR-MIDDLE OAK CREEK and its proximity to the city of FARMSTEAD highlight its importance in safeguarding the surrounding environment and residents from potential water-related risks.
Despite its age, Oak-Middle 82-B (Modified) continues to undergo regular inspections to ensure its structural integrity and functionality. With a high hazard potential and a satisfactory condition assessment, this dam remains a key component in the local water resource management system. Its design by the USDA NRCS and oversight by the Nebraska Department of Natural Resources underscore the collaborative efforts involved in maintaining and operating this essential flood risk reduction infrastructure.

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 82-B (Modified)
Where does the data for Oak-Middle 82-B (Modified) 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 High 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.
