Summary

This private dam serves primarily for flood risk reduction but also offers recreational opportunities. Standing at 19 feet tall and stretching 300 feet in length, the earth-filled structure holds a maximum storage capacity of 138 acre-feet and covers a surface area of 6.8 acres.

Managed by the Iowa Department of Natural Resources, Stalkfleet Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and safety. The dam's low hazard potential and moderate risk rating make it a vital asset for managing water resources and mitigating potential flooding risks in the region. With its uncontrolled spillway and stone core foundation, the dam plays a crucial role in protecting the surrounding area from the impacts of high water events.

Enthusiasts of water resources and climate will appreciate the strategic location and design of Stalkfleet Dam, which not only reduces flood risks but also enhances the local ecosystem and provides recreational opportunities. The dam's presence on a tributary to Sweetland Creek highlights its importance in managing water flow and maintaining water quality in the area. As a privately owned structure with state oversight, Stalkfleet Dam represents a successful collaboration between public and private entities to safeguard communities and natural resources from the impacts of extreme weather events.

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.
