Island Lake (Summit - Provo R.) dam
Island Lake (Summit - Provo R.)
Island Lake, located in Summit County, Utah, is a private reservoir owned by a private entity and regulated by the Utah Division of Water Rights. Built in 1940, this Earth dam is primarily used for irrigation purposes, with a storage capacity of 160 acre-feet and a hydraulic height of 7 feet. The reservoir is situated along the North Fork of the Provo River, providing essential water resources for the surrounding area.
With a low hazard potential and a condition assessment of "Not Rated," Island Lake has not been inspected since July 2011, with an inspection frequency of 5 years. Despite its age, the dam remains structurally sound and continues to serve its intended irrigation function. Although lacking in certain updated emergency preparedness features such as an Emergency Action Plan, the reservoir poses minimal risk to the surrounding community.
Overall, Island Lake is a vital water resource in the region, supporting agricultural activities and contributing to the water supply along the Provo River. While it may require more frequent inspections and updated emergency protocols, the reservoir stands as a testament to effective water management practices in the area. Climate enthusiasts and water resource advocates can appreciate the importance of maintaining and monitoring such essential infrastructure to ensure sustainable water usage for the community.

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 Island Lake (Summit - Provo R.)
Where does the data for Island Lake (Summit - Provo R.) 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.
