Rappahannock Dam #17 dam
Rappahannock Dam #17
Rappahannock Dam #17, located in Rappahannock, Virginia, is a state-regulated dam with a height of 19.75 feet and a storage capacity of 119.61 acre-feet. The dam, designated as NIDID VA157017, is owned by an entity not listed and falls under the jurisdiction of the Department of Conservation and Recreation in Virginia. While the dam's hazard potential is currently undetermined and its condition has not been rated, it undergoes regular inspections with a frequency of 1.
Despite lacking specific information on its construction year and purposes, Rappahannock Dam #17 plays a crucial role in water resource management in the region. Situated in the Baltimore District, the dam stands as a key structure in safeguarding the surrounding area against potential flooding events and ensuring a stable water supply for various stakeholders. With its strategic location and significant storage capacity, the dam serves as a vital asset in the state's efforts to manage water resources and mitigate the impacts of climate change in the region.
Although details about the dam's design, foundation, and spillway remain unspecified, Rappahannock Dam #17 stands as a testament to the collaborative efforts between state agencies and regulatory bodies to uphold safety standards and protect communities from water-related risks. As water resource and climate enthusiasts continue to monitor and advocate for sustainable practices, the presence of dams like Rappahannock Dam #17 underscores the importance of proactive measures in ensuring the resilience and longevity of our water infrastructure in the face of evolving environmental challenges.

About Rappahannock Dam #17
Where does the data for Rappahannock Dam #17 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 Undetermined 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.

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.
