Summary

This rockfill dam structure spans 1140 feet in length and stands at a height of 6.3 feet, with a storage capacity of 220 acre-feet. The slough covers an area of 18 acres and is fed by Beaver Creek-TR, making it a vital resource for the surrounding ecosystem.

Managed by the Minnesota Department of Natural Resources, Engbarth Slough is classified as having a low hazard potential and has not been rated for its condition assessment. Despite this, the slough undergoes regular inspections every 8 years to ensure its structural integrity and compliance with state regulations. While the exact year of completion is unknown, Engbarth Slough continues to serve as a valuable water resource for the community, contributing to the preservation of wildlife and the enhancement of the local environment. As a water resource and climate enthusiast, Engbarth Slough presents a unique opportunity to appreciate the intersection of human intervention and environmental stewardship in maintaining a balanced ecosystem.

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.
