Havvaski Waterski Pond dam
Havvaski Waterski Pond
Havvaski Waterski Pond is a private water recreation facility located in Thurston, Washington. Managed by the Washington Department of Ecology, this man-made water body sits on the Tr-Black River and offers enthusiasts a chance to enjoy waterskiing and other water sports. Completed in 1992, the pond has a hydraulic height of 12 feet and a length of 3500 feet, providing ample space for outdoor fun.
With a storage capacity of 110 acre-feet and a surface area of 83 acres, Havvaski Waterski Pond is a popular destination for water resource and climate enthusiasts in the region. The dam, primarily made of earth and stone, has a low hazard potential and is not currently rated for condition assessment. Despite its remote location and minimal infrastructure, the pond is well-maintained and regularly inspected for safety, ensuring a pleasant and secure experience for visitors.
Congressional District 10, Washington, is represented by Denny Heck (D), who oversees the management and regulation of the pond. While there are no associated structures or locks, the facility's primary purpose of recreation attracts a steady flow of visitors seeking outdoor adventure. Whether you're a seasoned waterskier or a nature lover looking to enjoy the tranquil surroundings, Havvaski Waterski Pond offers a unique and refreshing escape from the hustle and bustle of everyday life.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Havvaski Waterski Pond
Where does the data for Havvaski Waterski Pond 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.
