Summary
The dam stands at a height of 34 feet and has a storage capacity of 143 acre-feet, serving as flood risk reduction infrastructure for the surrounding area. Located in Correctionville, the dam is situated on the TR- Little Sioux River and falls under the regulatory oversight of the Iowa DNR.
With a low hazard potential and a moderate risk assessment rating of 3, Bitter Creek Subwatershed Site E-2 plays a crucial role in managing water resources in the region. The dam's design and construction were funded by the Natural Resources Conservation Service, and it is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. While the dam has not been rated for its current condition, it remains an important asset for water management and environmental protection efforts in the area.
As part of the Rock Island District, the Bitter Creek Subwatershed Site E-2 contributes to the overall water infrastructure in Iowa, serving multiple purposes beyond flood risk reduction. Its strategic location and design make it a valuable resource for fire protection, livestock watering, and recreational fishing opportunities. With its storage capacity, surface area, and drainage area, the dam embodies sustainable water management practices and underscores the importance of maintaining and monitoring critical infrastructure for climate resilience and water security.

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.
