Lory Lake Structure 1 dam
Lory Lake Structure 1
Lory Lake Structure 1, also known as Cranberry Wma Lory Lake, is a state-owned gravity dam located in Isanti, Minnesota. Completed in 1962, this structure serves as a Fish and Wildlife Pond with a storage capacity of 2100 acre-feet. With a structural height of 16 feet and a length of 800 feet, Lory Lake Structure 1 plays a crucial role in managing water resources in the area.
The dam is situated on Ties Creek-TR and has a drainage area of 4 square miles, with a surface area of 341 acres. Despite its low hazard potential and satisfactory condition assessment, the risk assessment categorizes Lory Lake Structure 1 as having a very high risk level. It is regularly inspected every 8 years by the Minnesota Department of Natural Resources, ensuring its safety and functionality for the surrounding environment.
With its controlled spillway and primary purpose of providing habitat for fish and wildlife, Lory Lake Structure 1 stands as a vital component of the water infrastructure in the region. Its significance lies not only in flood control and water storage but also in supporting the ecological diversity and sustainability of the area. For water resource and climate enthusiasts, understanding the role and condition of structures like Lory Lake Structure 1 is essential for promoting effective water management practices.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lory Lake Structure 1
Where does the data for Lory Lake Structure 1 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.
