Hawkins dam
Hawkins
Hawkins, a private water resource in Idaho, is a crucial component of the state's irrigation infrastructure. Built in 1870, this earth dam on Hawkins Creek and Marsh Creek has a height of 35.1 feet and a storage capacity of 880 acre-feet. With a significant hazard potential and fair condition assessment, Hawkins is subject to frequent inspections by the Idaho Department of Water Resources to ensure its structural integrity and safety.
Managed by the Natural Resources Conservation Service, Hawkins features an uncontrolled spillway and a slide gate outlet for water release. The dam's proximity to Marsh Center in Bannock County makes it a key resource for agricultural irrigation in the region. Its moderate risk assessment of 3 highlights the importance of ongoing risk management measures to mitigate potential hazards and ensure the continued functionality of Hawkins for water supply and flood control purposes.
Located within the Walla Walla District, Hawkins plays a vital role in water management and conservation efforts in Idaho. With a drainage area of 26.6 square miles and a maximum discharge capacity of 418 cubic feet per second, this dam exemplifies the intersection of water resource management and climate resilience. As climate change impacts water availability and quality, maintaining and enhancing infrastructure like Hawkins becomes increasingly crucial for sustainable water resource management in the state.
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 Hawkins
Where does the data for Hawkins 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 Significant 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.
