Summary
Built in 1958 by the USDA NRCS, this earth dam stands at a height of 31 feet, serving primarily for flood risk reduction purposes. With a storage capacity of 87 acre-feet and a drainage area of 0.7 square miles, this dam plays a vital role in managing water flow and protecting the surrounding areas from potential flooding events.
The dam has a low hazard potential and is currently in satisfactory condition, as per the last inspection in April 2018. With a structural height of 32 feet and a hydraulic height of 30 feet, Brownell Creek 10-2 spans 610 feet in length and covers a surface area of 3 acres. The dam's normal storage capacity is 16 acre-feet, while its maximum discharge capacity reaches 1968 cubic feet per second. Despite its modest size, this dam plays a crucial role in water management and flood control within the region.
Situated in the watershed of TR-Brownell Creek and managed by the Natural Resources Conservation Service, Brownell Creek 10-2 is a testament to effective collaboration between local and federal agencies in safeguarding water resources and mitigating flood risks. With a history of successful operation dating back to its completion in 1958, this dam continues to play a vital role in ensuring the resilience and sustainability of the water infrastructure in Otoe County, Nebraska.

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.
