Lazy J-D #1 dam
Lazy J-D #1
Lazy J-D #1 is a private irrigation dam located in Phillips County, Montana, along Rock Creek. Built in 1952, this earth dam stands at a height of 30 feet and spans 600 feet in length, with a storage capacity of 356 acre-feet. Managed by the Montana Department of Natural Resources and Conservation (DNRC), Lazy J-D #1 is regulated, permitted, inspected, and enforced by the state, ensuring its safe operation and maintenance. Despite its low hazard potential, the dam's condition remains unrated, with no recent inspection data available.
Situated in a remote area with no associated city, Lazy J-D #1 serves as a crucial water resource for irrigation purposes in the region. Owned privately, the dam is not federally funded or managed, highlighting the importance of state oversight in ensuring its functionality. With its location in the Congressional District 00 of Montana, Lazy J-D #1 contributes to the agricultural landscape of the area, supporting the water needs of local farmers and landowners. While lacking specific data on risk assessments and emergency preparedness, the dam's presence underscores the intersection of water management, climate resilience, and agricultural sustainability in the region.
As a significant structure in the Omaha District of the US Army Corps of Engineers, Lazy J-D #1 symbolizes the intricate network of dams and reservoirs that shape water resources management in Montana. With its historical significance dating back to the mid-20th century, the dam stands as a testament to the enduring legacy of irrigation infrastructure in the state. While its current condition assessment is pending, Lazy J-D #1 remains a vital component of the water supply system, highlighting the ongoing challenges and opportunities in managing water resources in a changing climate landscape.
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 Lazy J-D #1
Where does the data for Lazy J-D #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.
