Dry Hollow Reservoir dam
Dry Hollow Reservoir
Dry Hollow Reservoir, located in Kane County, Utah, is a privately-owned irrigation reservoir regulated by the Utah Division of Water Rights. With a capacity of 51.6 acre-feet and a hydraulic height of 27 feet, this earth dam structure serves the primary purpose of supporting agricultural irrigation activities in the region. Despite its low hazard potential and a last inspection date in 2016, the condition assessment of the reservoir has not been rated, indicating a need for further evaluation to ensure its long-term safety and efficiency.
Situated in a picturesque setting with coordinates at 37.46627249 latitude and -112.4392801 longitude, Dry Hollow Reservoir stands as a vital water resource within the region's water infrastructure. The reservoir boasts a maximum discharge rate of 4.2 cubic feet per second and a spillway width of 20 feet, catering to the water needs of the surrounding area. While the reservoir's emergency action plan status and risk assessment details are not provided, its role in sustaining agricultural operations underscores the importance of ongoing monitoring and maintenance to safeguard water availability and quality in the face of changing climatic conditions.
As climate change impacts continue to influence water resources and availability, the significance of reservoirs like Dry Hollow in supporting irrigation and agricultural activities cannot be understated. With regulatory oversight from the Utah Division of Water Rights and low hazard potential, ensuring the structural integrity and functionality of this vital water storage facility is crucial for sustainable water management in the region. By prioritizing regular inspections, risk assessments, and maintenance activities, stakeholders can enhance the resilience of Dry Hollow Reservoir and its capacity to meet the evolving water needs of the community amidst a changing climate landscape.

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 Dry Hollow Reservoir
Where does the data for Dry Hollow Reservoir 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.
