Summit Development Dam
Summit Development
Summit Development, Pond N8 is a privately owned dam located in Washington County, Utah, designed for flood risk reduction. The dam is regulated by the Utah Division of Water Rights and is subject to state inspection and enforcement. With a structural height of 14 feet and a length of 672 feet, the dam has a storage capacity of 9.68 acre-feet and a drainage area of 0.39 square miles.
Although the dam's hazard potential is deemed significant, its condition assessment is currently not rated. The dam does not have an Emergency Action Plan (EAP) in place, and there are no inundation maps prepared for potential risk assessment. However, the dam meets state permitting and inspection requirements, with inspections occurring every 5 years. The dam's spillway width is 10 feet, and it has a maximum discharge capacity of 12 cubic feet per second.
Summit Development, Pond N8 serves as a vital infrastructure for flood risk mitigation in the region, under the oversight of the Utah Division of Water Rights. Despite its significant hazard potential, the dam's condition assessment remains pending, highlighting the need for further evaluation and emergency preparedness measures. As water resource and climate enthusiasts, monitoring and ensuring the safety and maintenance of dams like Summit Development, Pond N8 is essential for sustainable water management and disaster prevention in the area.

About Summit Development
Where does the data for Summit Development 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 below 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.
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.
