Cook Southeast Dam dam
Cook Southeast Dam
Cook Southeast Dam, located in Alliance, Nebraska, serves multiple purposes including fire protection, stock, and small fish pond management. This private dam on Snake Creek was completed in 1953 and stands at a height of 6.7 meters, with a storage capacity of 123.2 acre-feet. While it has a low hazard potential, the dam is state-regulated, inspected, and enforced by the Nebraska Department of Natural Resources.
The dam, primarily constructed with earth and stone materials, spans 455 meters and covers a surface area of 28.1 acres within a drainage area of 187.5 square kilometers. Its maximum discharge capacity reaches 902 cubic meters per second, ensuring effective flood control and water management in the region. Despite not being rated for its condition, the dam has undergone regular inspections every 10 years, with the last assessment taking place in February 2012.
Overall, Cook Southeast Dam represents a vital infrastructure element in Box Butte County, Nebraska, providing essential water resources for various uses while maintaining a low-risk profile. As climate change impacts water availability and quality, such dams play a crucial role in ensuring sustainable water management practices and supporting ecosystem health in the region. With proper regulation, inspection, and maintenance, dams like Cook Southeast Dam contribute to the resilience of local communities and ecosystems against the challenges posed by a changing climate.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Cook Southeast Dam
Where does the data for Cook Southeast Dam 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.
