Lee #11 dam
Lee #11
Lee #11, located in Kinsey, Montana, is a state-regulated earth dam built in 1950 for irrigation purposes on the TR-South Sunday Creek. With a height of 15 feet and a storage capacity of 89 acre-feet, this dam plays a crucial role in providing water for agricultural activities in the area. Despite its low hazard potential, the condition of Lee #11 is currently not rated, highlighting the need for regular inspections and maintenance to ensure its continued safety and functionality.
This dam, under the jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC), is situated in Rosebud County and falls under Congressional District 00. Although its last inspection date and condition assessment are not specified, the presence of state permitting, inspection, and enforcement processes ensures that necessary measures are in place to address any potential risks associated with the dam. With a primary purpose of irrigation, Lee #11 serves as a vital water resource in the region, storing water for agricultural use and contributing to the sustainability of local farming operations.
As water resource and climate enthusiasts explore the significance of Lee #11, its role in water management and agricultural sustainability becomes evident. With its location in the Omaha District and the oversight of the DNRC, this earth dam stands as a testament to human ingenuity in harnessing water resources for the benefit of communities. Moving forward, continued monitoring and maintenance efforts will be essential to ensure the long-term resilience and functionality of Lee #11, safeguarding its contribution to the region's water security and agricultural productivity.

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 Lee #11
Where does the data for Lee #11 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.
