Summary
This earth dam, completed in 1979 by the USDA NRCS, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a dam height of 47 feet and a storage capacity of 251 acre-feet, this structure plays a significant role in water management within the watershed.
The dam's low hazard potential and moderate risk assessment make it a relatively stable infrastructure for water resource management. Although the condition assessment is currently not rated, the Iowa DNR oversees state regulation, permitting, inspection, and enforcement to ensure the safety and functionality of Mosquito Creek Watershed Site 6-5. The dam's location along TR-Mosquito Creek contributes to the protection and preservation of water resources in the area, with a drainage area of 0.82 square miles and a surface area of 10.5 acres.
Overall, Mosquito Creek Watershed Site 6-5 stands as a critical piece of infrastructure for water resource and climate enthusiasts. With its strategic design, purposeful construction, and state regulation, this earth dam plays a vital role in flood risk reduction and water management in the region, highlighting the importance of sustainable water resource practices in safeguarding our environment.

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.
