Summary
Constructed in 1955 by the USDA NRCS, this dam serves as a crucial flood risk reduction infrastructure along the TR-Brownell Creek. With a height of 30 feet and a length of 630 feet, the dam has a storage capacity of 88 acre-feet and a drainage area of 0.3 square miles.
Managed by the NE DNR, Brownell Creek 6-A has a low hazard potential and is in satisfactory condition as of the last inspection in June 2016. The dam features stone core and soil foundation, with a design focused on flood risk reduction. Its location in TALMAGE, Nebraska, makes it a significant structure for water resource management in the region, with a normal storage capacity of 18 acre-feet and a maximum discharge rate of 616 cfs.
Overall, Brownell Creek 6-A plays a critical role in protecting the surrounding community from potential flooding events. With state-regulated operations, inspections, and enforcement in place, this dam exemplifies effective water resource management and climate resilience efforts in Nebraska. Its strategic design and construction by the Natural Resources Conservation Service highlight the importance of sustainable infrastructure for mitigating flood risks and ensuring the safety of local residents.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
