Summary
Owned privately, the dam is regulated by the Minnesota Department of Natural Resources, ensuring that it meets state inspection and enforcement standards. With a height of 25.7 feet and a storage capacity of 19.8 acre-feet, Stately 29 serves as a vital infrastructure for protecting the surrounding area from potential flooding events.
Despite its low hazard potential, Stately 29 plays a crucial role in safeguarding the community by providing flood risk reduction measures. The dam's primary purpose aligns with its construction as a rockfill structure with a buttress core type. While its condition assessment is currently not rated, regular inspections are conducted every 8 years to ensure its operational integrity. Moreover, the dam's location in Brown County underscores its importance in managing water resources and climate impacts in the region.
As water resource and climate enthusiasts, understanding the specifications of Stately 29 sheds light on the critical role that infrastructure plays in mitigating natural disasters. With a storage capacity of 19.8 acre-feet and a drainage area of 0.14 square miles, the dam's design and purpose emphasize the importance of proactive measures in flood risk management. As efforts continue to enhance the dam's safety and operational efficiency, Stately 29 stands as a testament to the ongoing commitment to water resource management in Minnesota.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
