Hooker dam
Hooker
Located in Garfield County, Montana, the Hooker dam serves multiple purposes including fire protection, stock water supply, and small fish pond management. Constructed in 1938, this earth dam stands at a height of 15 feet with a length of 175 feet, providing a storage capacity of 50 acre-feet. Situated on TR-Big Dry Creek, this low hazard potential dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state inspection and enforcement.
Owned privately, the Hooker dam is essential for ensuring water security in the region, particularly for fire protection and livestock watering needs. Positioned in a rural area near Jordan, Montana, this dam plays a vital role in supporting the local community's water resource management. With its modest storage capacity and low hazard potential, the Hooker dam stands as a testament to the importance of small-scale water infrastructure in sustaining both human and environmental needs.
As a key feature in the Big Dry Creek watershed, the Hooker dam not only provides crucial water resources but also contributes to the overall ecological health of the region. While its condition is currently rated as "Not Rated," ongoing state regulation, inspection, and enforcement ensure the safety and functionality of this important water management structure. With its historical significance and practical utility, the Hooker dam remains a valuable asset for water resource and climate enthusiasts interested in sustainable water infrastructure.

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 Hooker
Where does the data for Hooker 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.
