Summary
Completed in 1962, this earth dam stands at 29 feet high and spans 315 feet in length, providing a storage capacity of 105 acre-feet and serving a drainage area of 160 square miles. With a spillway width of 50 feet and a maximum discharge of 802 cubic feet per second, the dam plays a crucial role in managing water flow and mitigating flood risks in the region.
Despite its high hazard potential and moderate risk assessment rating, Platte River Trib Watershed Dam 3-B has not been inspected since June 1980 and is currently not rated for its condition. While no emergency action plan or inundation maps are in place, the dam continues to serve its primary purpose of grade stabilization effectively. With its stone core and soil foundation, this structure exemplifies the importance of sustainable water resource management in the face of evolving climate challenges. As water resource and climate enthusiasts, there is much to learn and appreciate from the engineering marvel that is Platte River Trib Watershed Dam 3-B, standing as a testament to the resilience and ingenuity of the local government and USDA NRCS in safeguarding our precious water resources.

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.
