About this dam

Eddie #1

Eddie #1 is a privately owned earth dam located in Nashua, Montana, along the TR-Middle Fork Porcupine Creek. Designed by the USDA NRCS and completed in 1969, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 15 feet and a length of 200 feet, Eddie #1 has a storage capacity of 51 acre-feet and a maximum discharge of 150 cubic feet per second. Despite its low hazard potential, the dam is regulated by the state and undergoes regular inspections to ensure its safety and functionality.

Situated in Valley County within Congressional District 00 of Montana, Eddie #1 is owned and regulated by a private entity. The dam is under the jurisdiction of the DNRC and is subject to state permitting, inspection, and enforcement. The primary source agency for Eddie #1 is the state of Montana, and its location at coordinates 48.7473° N, -106.4426° W makes it a crucial water resource for the local community. With its primary purpose being fire protection and stock watering, Eddie #1 plays a vital role in providing essential water resources for various uses in the area.

Although Eddie #1 is classified as a low hazard dam with a condition assessment of "Not Rated," its importance in providing water for fire protection and livestock makes it a significant asset in the region. With a history dating back to 1969, this earth dam continues to serve its intended purposes while being regulated by the state to ensure its safety and efficiency. For water resource and climate enthusiasts, Eddie #1 represents a key infrastructure that contributes to water management and conservation efforts in Montana's Valley County.

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 Eddie #1

Where does the data for Eddie #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.
