Boulder Lake Dike Cc dam
Boulder Lake Dike Cc
Boulder Lake Dike Cc, located in St. Louis County, Minnesota, is a key structure managed by the Federal Energy Regulatory Commission for hydroelectric purposes. Built in 1919, this earth dam stands at a height of 20 feet and has a storage capacity of 30,300 acre-feet. With a primary purpose of hydroelectric power generation, the dam also serves recreational activities in the area. The dam is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
The dam on Otter Creek is associated with two other structures and is situated within the St. Paul District of the US Army Corps of Engineers jurisdiction. Despite its low hazard potential, Boulder Lake Dike Cc has not had a recent condition assessment available. The last inspection was conducted in September 2018, with an inspection frequency of every 3 years. While emergency action plans and risk management measures are not specified, the dam continues to play a vital role in water resource management and energy production in the region.
As a focal point for water resource and climate enthusiasts, Boulder Lake Dike Cc stands as a historic landmark in Minnesota's infrastructure landscape. With its dual purpose of hydroelectric power generation and recreational use, the dam plays a crucial role in balancing environmental conservation and energy needs. While its hazard potential is deemed low, ongoing inspections and regulatory oversight ensure the safety and integrity of this essential structure for the community and the surrounding 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.
- 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.
- 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.
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, environmental 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.

About Boulder Lake Dike Cc
Where does the data for Boulder Lake Dike Cc come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
