About this dam

Jordan Reservoir #1

Jordan Reservoir #1, also known as Jordan's Red Water, is a privately owned irrigation reservoir located in McCone, Montana. Constructed in 1969, this earth dam structure stands at a height of 28 feet and has a storage capacity of 1370 acre-feet. The reservoir, situated on the Redwater River, serves as a vital water source for agricultural irrigation in the region.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Jordan Reservoir #1 is regulated, inspected, and enforced by the state to ensure its safe operation. With a low hazard potential and a condition assessment of "Not Rated", the reservoir is considered a reliable water resource for the surrounding community. While the dam is not part of the US Army Corps of Engineers, its importance in sustaining local agriculture highlights the significance of water management in the face of changing climate patterns.

Despite its modest size and low-risk profile, Jordan Reservoir #1 plays a crucial role in supporting the irrigation needs of farmers in the area. As water resources become increasingly strained due to climate variability, the responsible management and maintenance of such reservoirs are essential for ensuring sustainable water supply for agricultural activities in Montana. With its location on the Redwater River and its operational history spanning over five decades, this reservoir stands as a testament to the importance of water infrastructure in mitigating the impacts of climate change on agricultural practices.

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.

FAQ

About Jordan Reservoir #1

Where does the data for Jordan Reservoir #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.
