Summary

The dam, situated on TR-Buffalo Creek, serves primarily for flood risk reduction and other purposes. With a height of 34 feet and a length of 740 feet, Buffalo Creek Gs-22 has a maximum storage capacity of 165 acre-feet and a drainage area of 1.3 square miles.

Maintained and regulated by the NE DNR, Buffalo Creek Gs-22 has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in September 2019. The dam's hydraulic height is 31 feet, with a structural height of 41 feet. Despite its modest surface area and normal storage capacity, Buffalo Creek Gs-22 plays a crucial role in mitigating flood risks in the region, with a maximum discharge rate of 580 cubic feet per second.

Water resource and climate enthusiasts can appreciate the strategic design and functionality of Buffalo Creek Gs-22 as a key infrastructure for flood risk management in the Cedar Creek area. The dam's earth construction, supported by stone core types and a soil foundation, underscores its reliability in safeguarding the surrounding community from potential inundation. As a state-regulated and inspected structure, Buffalo Creek Gs-22 exemplifies the collaborative efforts between local government agencies and the USDA NRCS in ensuring the resilience of water resource systems against adverse weather events.

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. 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

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, 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.
