Summary

Park Dam #1, located in Mc Causland, Iowa, is a locally owned earth dam constructed in 1964 by Stanley & Associates. This dam, standing at a height of 20 feet and stretching 540 feet in length, serves the primary purpose of water resource management along Tr- Glynns Creek. With a storage capacity of 169 acre-feet, the dam plays a crucial role in regulating water flow and maintaining a surface area of 6.8 acres.

Managed by the Iowa Department of Natural Resources, Scott Co. Park Dam #1 is classified as having a low hazard potential with a moderate risk assessment score of 3. Although the condition assessment is not rated, the dam undergoes regular state inspections, permitting, and enforcement to ensure its structural integrity and operational effectiveness. With a drainage area of 0.2 square miles, the dam contributes to flood control efforts and supports the sustainable use of water resources in the region.

Water resource and climate enthusiasts can appreciate Scott Co. Park Dam #1 as a vital infrastructure that plays a significant role in water management in Scott County, Iowa. With its strategic location and design, the dam not only helps in controlling water flow and storage but also enhances the resilience of the local ecosystem to climate-related challenges. As a locally owned and state-regulated structure, it stands as a testament to the collaborative efforts towards sustainable water resource management and environmental protection in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
