Dam 2-7-5w dam
Dam 2-7-5w
Dam 2-7-5w, located in Clay County, Nebraska, is a crucial structure owned by the local government and regulated by the Nebraska Department of Natural Resources. Built in 1994 by the Upper Big Blue NRD, this earth dam stands at a height of 14 feet and serves primarily for flood risk reduction along the TR-School Creek. With a storage capacity of 57 acre-feet and a drainage area of 0.23 square miles, Dam 2-7-5w plays a vital role in mitigating potential hazards and maintaining water resources in the region.
Despite its satisfactory condition assessment, Dam 2-7-5w is categorized with a high hazard potential, highlighting the importance of regular inspections and maintenance. The dam's emergency action plan (EAP) was last revised in November 2016, with an inspection frequency of once per year. The structure has a structural height of 19 feet and a hydraulic height of 13 feet, with a maximum discharge capacity of 1259 cubic feet per second, further emphasizing its significance in managing water flow and potential flooding risks in the area.
As part of flood risk reduction efforts, Dam 2-7-5w serves as a key infrastructure project in the region, safeguarding against potential disasters and ensuring the safety of nearby communities. With its strategic location and design features, this earth dam continues to play a crucial role in water resource management and climate resilience efforts in Clay County, Nebraska.

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 Dam 2-7-5w
Where does the data for Dam 2-7-5w 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.
