Longview Lake Upper Dam dam
Longview Lake Upper Dam
Longview Lake Upper Dam in Wake, North Carolina, is a privately owned structure regulated by the NCDEQ Dam Safety Program. Situated on Crabtree Creek-Tr, this earth-type dam serves primarily for recreational purposes with a hydraulic height of 11.1 feet and a structural height of 14.7 feet. The dam has a normal storage capacity of 24 acre-feet and covers a surface area of 5.5 acres, providing essential water resources for the region.
With a high hazard potential and fair condition assessment as of August 2020, Longview Lake Upper Dam is subject to regular inspections every two years to ensure its safety and integrity. The dam's Emergency Action Plan was last revised in June 2015, highlighting the importance of proactive risk management measures to mitigate any potential threats. Despite its private ownership, the dam plays a crucial role in the water resource management of the area, emphasizing the need for ongoing monitoring and maintenance efforts to safeguard against any environmental risks.
As a key feature in the recreational landscape of Raleigh, Longview Lake Upper Dam contributes to the local community's enjoyment while also serving as a vital water resource for the region. Its strategic location and purposeful design underscore the intersection of environmental conservation and public recreation, making it an essential structure for water resource and climate enthusiasts to appreciate and prioritize in their advocacy efforts.

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 Longview Lake Upper Dam
Where does the data for Longview Lake Upper Dam 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.
