Summary
Constructed in 1999 by the USDA NRCS, this earth dam stands at a height of 27 feet and has a storage capacity of 99 acre-feet, serving multiple purposes including fire protection, stock and fish ponds, and wildlife conservation. With a low hazard potential and moderate risk assessment, this dam plays a crucial role in mitigating flood risks in the region.
The structure spans 430 feet in length and covers a surface area of 4 acres, with a drainage area of 147.2 square miles. Despite its uncontrolled spillway type, the dam has a maximum discharge capacity of 132 cubic feet per second. While the condition assessment is currently not rated, regular inspections are conducted every five years to ensure its operational efficiency. With no outlet gates and a structural height of 30 feet, East Yellow Creek H-34 is a key asset in the flood management infrastructure of Linn County, Missouri.
Managed by the local government and with no state regulation or permitting requirements, East Yellow Creek H-34 epitomizes effective collaboration between federal and local agencies in flood risk reduction efforts. As climate change continues to impact water resources and weather patterns, structures like H-34 will play an increasingly vital role in safeguarding communities and ecosystems from the consequences of extreme weather events. The dedication of the USDA NRCS and the Rock Island District in designing and maintaining this earth dam underscores the importance of proactive measures in adapting to a changing climate and ensuring water resource sustainability 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.
