Summary
Designed by the USDA NRCS and completed in 1987, this dam primarily serves the purpose of flood risk reduction, with additional functions for debris control. With a height of 28.7 feet and a length of 795 feet, the dam has a storage capacity of 187 acre-feet and a drainage area of 0.48 square miles.
Despite being classified as having a low hazard potential, Gsd No B-45 (Gc 8) is rated as having a moderate risk level, indicating potential vulnerabilities that require attention. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. While the condition assessment is listed as "not rated," the risk management measures and emergency action plan status are not specified. Given its location and purpose, this dam plays a crucial role in mitigating flood risks in the Atchison County area.
Water resource and climate enthusiasts would find Gsd No B-45 (Gc 8) an intriguing structure to study, with its unique design features and historical significance in the local flood risk reduction efforts. As part of the Rock Island District, this dam exemplifies the collaborative efforts between local governments and federal agencies, such as the Natural Resources Conservation Service, in managing water resources and protecting communities from potential disasters. Further research and monitoring of this dam could provide valuable insights into sustainable water resource management practices and resilience-building strategies for climate-related challenges 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.
