Summary
This earth dam was constructed in 1966 by the USDA NRCS for purposes including fire protection, stock, small fish pond maintenance, and flood risk reduction. With a height of 31 feet and a length of 509 feet, the dam has a storage capacity of 60 acre-feet, serving a drainage area of 0.75 square miles. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, and inspections and emergency preparedness measures are yet to be documented.
Owned and regulated by the local government and overseen by the Iowa DNR, Reed Subwatershed Sta 88+35 #2 plays a vital role in managing water resources in Monona County. While the dam's primary purpose is to provide essential water services, its impact extends to flood control and environmental conservation efforts within the region. The dam's location and design, in conjunction with the surrounding natural landscape, contribute to the overall resilience of the area's water infrastructure.
As water resource and climate enthusiasts continue to monitor and evaluate the sustainability of Reed Subwatershed Sta 88+35 #2, collaboration among stakeholders, ongoing assessments, and proactive risk management measures will be essential to ensure the long-term functionality and safety of this critical water structure. By recognizing the interconnectedness of water resource management and climate resilience, efforts can be directed towards enhancing the dam's effectiveness and promoting sustainable water practices 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.
