About this dam

Davis County -Holmes Creek Db

Davis County -Holmes Creek Db is a private dam located in Kaysville, Utah, specifically on Holmes Creek in Webb Canyon. Built in 1984 for flood risk reduction, this earth dam stands at a hydraulic height of 14 feet and a structural height of 22 feet, with a length of 900 feet. It has a storage capacity of 26 acre-feet and a drainage area of 3 square miles, with a maximum discharge of 91 cubic feet per second. Despite its high hazard potential, the dam is currently in fair condition according to the last inspection in June 2019.

Operated by the Utah Division of Water Rights, Davis County -Holmes Creek Db is regulated, permitted, inspected, and enforced by the state of Utah. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation. With a location in the Omaha District, this dam plays a crucial role in managing water resources in the region. While it meets regulatory guidelines and has emergency contacts in place, there is currently no detailed risk assessment or management plan available for this structure.

In the picturesque county of Davis, Utah, the Holmes Creek Db dam stands as a vital infrastructure for water resource management and climate resilience. With its strategic location and functional design, this dam serves as a critical barrier against flood risks, showcasing the intersection of engineering excellence and environmental stewardship. As water enthusiasts and climate advocates, it is important to monitor and support the ongoing maintenance and regulatory efforts for this essential piece of infrastructure in the region.

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 Davis County -Holmes Creek Db

Where does the data for Davis County -Holmes Creek Db 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 High 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.

Premium feature
