Barnaby Slough No 2 Dam dam
Barnaby Slough No 2 Dam
Barnaby Slough No 2 Dam is a privately owned structure located in Rockport, Washington, along the Tr-Skagit River. Completed in 1968, this Earth-type dam stands at a hydraulic height of 14 feet with a structural height of 9 feet. With a primary purpose of serving as a Fish and Wildlife Pond, the dam has a normal storage capacity of 124 acre-feet and a total storage capacity of 157 acre-feet. It covers a surface area of 43 acres and has a drainage area of 4.33 square miles.
Despite its low hazard potential, Barnaby Slough No 2 Dam is regulated by the Washington Department of Ecology and undergoes regular state inspections, enforcement, and permitting. The dam has not been rated for its condition, with the last inspection conducted in May 1998. While it has not been modified in recent years, the dam continues to play a vital role in supporting fish and wildlife in the area. The dam's location in the Skagit County and its proximity to the Congressional District 01 further highlight its significance in the region.
Water resource and climate enthusiasts will find Barnaby Slough No 2 Dam to be an intriguing structure that contributes to the conservation of local fish and wildlife populations. Its modest size and purpose make it a valuable asset for the community, serving as a reminder of the importance of sustainable water management practices. As a state-regulated dam with a long history of operation, Barnaby Slough No 2 Dam stands as a testament to the ongoing efforts to balance environmental conservation with human infrastructure development in Washington state.

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 Barnaby Slough No 2 Dam
Where does the data for Barnaby Slough No 2 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 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.
