Summary
This earth dam stands at a height of 23 feet and has a hydraulic height of 15 feet, with a storage capacity of 128.1 acre-feet. Its primary purpose is flood risk reduction, serving the surrounding area by controlling the flow of the unnamed stream that feeds into East Yellow Creek. The dam has a low hazard potential and a moderate risk assessment rating, making it a crucial infrastructure for managing water resources in the region.
Constructed by the Natural Resources Conservation Service, East Yellow Creek B-48 plays a vital role in regulating water flow and reducing the risk of flooding in the area. With a surface area of 7 acres and a drainage area of 326.4 square miles, this dam helps protect nearby communities and infrastructure from potential water-related disasters. Despite being not rated for its condition assessment, the dam's design and construction reflect a commitment to water resource management and climate resilience in the region.
As part of the Rock Island District, East Yellow Creek B-48 is a significant component of the local flood control system, with a spillway width of 30 feet and a maximum discharge capacity of 198.3 cubic feet per second. While the dam has not been modified in recent years, its strategic location and operational efficiency continue to contribute to the overall water management efforts in Missouri. For water resource and climate enthusiasts, East Yellow Creek B-48 represents a crucial infrastructure investment in safeguarding communities and ecosystems from the impacts of extreme weather events.

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.
