Summary
Completed in 1981, this dam serves a primary purpose of flood risk reduction and storage with a hydraulic height of 29 feet and a structural height of 31 feet. It has a normal storage capacity of 30 acre-feet and a maximum discharge of 752 cubic feet per second, protecting the surrounding area from potential flooding events.
With a low hazard potential and fair condition assessment as of April 2018, Long Branch R-3 plays a crucial role in managing water resources in Richardson County. The dam has a drainage area of 0.6 square miles and serves as a vital structure for water storage and flood control along Long Branch Creek. This earth dam, constructed with stone core types and soil foundations, covers a surface area of 7 acres and has a total length of 625 feet, providing essential infrastructure for water resource management in the region.
Despite its modest size, Long Branch R-3 represents a key component of the water infrastructure in Richardson County, Nebraska. With state regulation, inspection, and enforcement in place, this dam ensures the safety and protection of the local community from potential flood risks. Managed by the Natural Resources Conservation Service, this dam stands as a testament to effective water resource management and climate resilience efforts in the region.

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.
