Summary
Managed by the local government and designed by the USDA NRCS, this earth dam stands at a height of 31 feet and spans a length of 543 feet. Completed in 2006, it serves to protect the surrounding area from potential flooding events, with a storage capacity of 88 acre-feet and a drainage area of 0.28 square miles.
Despite its low hazard potential, East Fork Grand River Watershed Site E-54 is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement processes to ensure its structural integrity and continued functionality. With a moderate risk assessment rating of 3, this dam plays a crucial role in mitigating flood risks in the region. Situated along TR- Lotts Creek, this site is a vital component of the water resource management infrastructure in the area, contributing to the overall resilience of the watershed against climate-related challenges.
The site's primary purpose of flood risk reduction aligns with its design and construction specifications, emphasizing the importance of proactive measures in safeguarding communities and ecosystems against the impacts of extreme weather events. With its strategic location and operational effectiveness, East Fork Grand River Watershed Site E-54 exemplifies a collaborative effort between local and federal agencies in promoting water resource sustainability and climate resilience in the state of Iowa.

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.
