Summary

Completed in 2008, this WMA boasts a storage capacity of 195 acre-feet and covers a surface area of 73 acres. Situated in Murray County, the location of the WMA along County Ditch 48 makes it an essential part of the local water resource network.

With a low hazard potential and a satisfactory condition assessment as of May 2018, Hjermstad Slough WMA serves as a vital habitat for diverse wildlife in the region. The WMA's association with Ducks Unlimited underscores its commitment to conservation efforts, and its state-regulated status ensures that it is closely monitored and maintained by the Minnesota Department of Natural Resources (MNDNR). Climate and water resource enthusiasts will appreciate the role that this WMA plays in supporting biodiversity and ecological resilience in the area.

As a site dedicated to fish and wildlife conservation, Hjermstad Slough WMA not only provides essential habitat for local species but also contributes to the overall health of the ecosystem. Managed by the state and designed by a renowned conservation organization, this WMA stands as a testament to the importance of preserving and protecting natural resources for future generations. Its strategic location and purposeful design make it a valuable asset in the broader context of water resource management and climate adaptation efforts.

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.
