Morris #1 (Toole) dam
Morris #1 (Toole)
Morris #1 in Toole, Montana, is a privately-owned irrigation dam designed by the USDA NRCS and regulated by the DNRC. Completed in 1948, this earth dam stands at 37 feet tall and stretches 300 feet in length, providing essential water storage for irrigation purposes. The dam has a maximum storage capacity of 115 acre-feet and a normal storage of 90 acre-feet, serving the agricultural needs of the area.
Located on Trail Creek in Toole County, Montana, Morris #1 plays a crucial role in ensuring water availability for irrigation in the region. With a low hazard potential and a condition assessment that is currently not rated, this dam is a vital component of the local water resource infrastructure. Although details about the last inspection date and inspection frequency are not provided, the dam's primary purpose of irrigation underscores its significance for sustainable water management.
Managed by the Natural Resources Conservation Service, Morris #1 exemplifies the collaborative efforts between federal and state agencies to regulate and maintain water infrastructure. With the dam's spillway width of 14 feet and a maximum discharge capacity of 60 cubic feet per second, it demonstrates a commitment to effective water flow management. While details about emergency response preparedness are not specified, the dam's presence highlights the importance of proactive measures in safeguarding water resources for future generations.
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 Morris #1 (Toole)
Where does the data for Morris #1 (Toole) 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.
