Summary
This site was completed in 1992 and is owned by the local government, with design input from the USDA NRCS. The primary purpose of this earth dam is flood risk reduction, serving a drainage area of 0.61 square miles with a storage capacity of 80 acre-feet.
The dam stands at a height of 25 feet and stretches 631 feet in length, with a normal storage capacity of 20 acre-feet. While its hazard potential is rated as low, the risk assessment deems it as moderate. Despite not being rated for its condition, Troublesome Cr Watershed Site 39-2 is equipped with uncontrolled spillways and soil foundations. It also falls under the jurisdiction of the Iowa DNR for regulation, permitting, inspection, and enforcement, ensuring its compliance with state standards for water resource management.
Water resource and climate enthusiasts will find Troublesome Cr Watershed Site 39-2 to be a significant infrastructure for flood risk reduction in the area. Through its strategic design and state-regulated oversight, this earth dam serves as a vital resource for managing water flow in the Troublesome Creek watershed. Its location in Atlantic, Iowa, and partnership with the USDA NRCS highlight the collaborative efforts in maintaining the site's functionality and contributing to overall water resource sustainability in the region.

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.
