Summary
Completed in 1964 for the primary purpose of flood risk reduction, this dam stands at a height of 30 feet and has a storage capacity of 995 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2016 reported it as poor, highlighting the need for maintenance and potential upgrades to ensure its continued effectiveness in mitigating flood risks in the area.
Situated on Clear Creek, this dam plays a crucial role in protecting the surrounding area from potential flooding events, with a maximum discharge capacity of 6700 cubic feet per second. The dam's location in a rural setting underscores its importance in safeguarding the local community and infrastructure from the detrimental impacts of flooding. With its stone core and soil foundation, Upper Clear Creek 1-B serves as a vital asset in managing water resources and climate-related risks in the region.
As water resource and climate enthusiasts, the data for Upper Clear Creek 1-B prompts reflection on the ongoing challenges faced in maintaining and upgrading aging infrastructure to address the evolving threat of extreme weather events. The poor condition assessment of the dam underscores the need for proactive measures to ensure its reliability and effectiveness in flood risk reduction. By leveraging knowledge and expertise in water resource management, stakeholders can work towards enhancing the resilience of critical infrastructure like Upper Clear Creek 1-B to better withstand the impacts of a changing climate.

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.
