Summary
The dam stands at 26 feet tall and spans 528 feet in length, with a storage capacity of 45 acre-feet. Its primary purpose is to prevent erosion and stabilize the surrounding area, specifically along Tr- Jim Branch. The site is regulated by the Iowa DNR and is subject to state permitting, inspection, and enforcement.
The dam at Turkey Creek Watershed Site 19-29 is classified as an Earth dam with a spillway type of Uncontrolled. Although it has a low hazard potential and has not been rated for condition assessment, the risk assessment for the site is moderate. The dam is not currently owned or funded by any federal agency, and its operations are managed by the local government. Despite its modest size and capacity, the site plays a crucial role in managing water resources and mitigating the impacts of climate events in the region.
Overall, Turkey Creek Watershed Site 19-29 serves as an essential infrastructure for grade stabilization and water management in the area, contributing to the overall conservation efforts in the region. Its presence underscores the importance of sustainable water resource management and highlights the collaborative efforts between local governments and federal agencies to address climate-related challenges in Iowa. The site's strategic location and design make it a critical component of the larger watershed system, ensuring the protection and preservation of the surrounding environment for years to come.

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.
