Summary

This earth dam, standing at a height of 10 feet with a length of 2125 feet, serves as a Fish and Wildlife Pond for the surrounding area. With a storage capacity of 77 acre-feet, the dam covers a surface area of 17.1 acres and has a drainage area of 0.37 square miles.

Managed by the Iowa Department of Natural Resources, the Waterhouse Wetland Dam is regulated, permitted, inspected, and enforced by state authorities. The dam's low hazard potential and moderate risk assessment make it a crucial component for water resource management and wildlife conservation in the region. Despite not being rated for its condition, the dam plays a significant role in maintaining the ecological balance of the TR-Dutch Creek watershed.

With its primary purpose of enhancing fish and wildlife habitats, the Waterhouse Wetland Dam stands as a testament to the importance of sustainable water resource management. Its construction and operation demonstrate a commitment to environmental stewardship and the preservation of natural ecosystems. As climate change continues to impact water availability and quality, structures like the Waterhouse Wetland Dam play a vital role in securing a resilient future for both wildlife and communities in the area.

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.
