Holland Lake Impoundment dam
Holland Lake Impoundment
Holland Lake Impoundment in Itasca, Minnesota is a federally owned earth dam completed in 1977 with a height of 13 feet and a length of 350 feet. The impoundment has a storage capacity of 800 acre-feet, with a normal storage level of 600 acre-feet and a surface area of 164 acres. It is located on Fletcher Creek within the St. Paul District and is regulated by the Minnesota Department of Natural Resources.
The dam's primary purpose is listed as "Other," with a low hazard potential and a condition assessment of "Not Rated." The last inspection was conducted in July 2008, with an inspection frequency of every 8 years. While there are no associated locks or spillways, the dam is equipped to handle a maximum discharge of 120 cubic feet per second. The impoundment's risk management measures, emergency action plan, and inundation maps have not been updated or assessed.
For water resource and climate enthusiasts, Holland Lake Impoundment offers a unique opportunity to study a relatively small but important structure within the Minnesota landscape. Its low hazard potential and state jurisdiction make it a valuable case study for understanding the management and regulation of water resources in the region. Further research and monitoring of the impoundment's condition and risk assessment measures could provide valuable insights into sustainable water resource management practices in the area.
Dam data reference
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 Holland Lake Impoundment
Where does the data for Holland Lake Impoundment 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.
