Tapps Lake Dike No 2b dam
Tapps Lake Dike No 2b
Tapps Lake Dike No 2b, located in Auburn, Washington, is a crucial structure that diverts water from the White River. Built in 1911, this earth dam serves primarily for recreation purposes, providing a surface area of 2570 acres and a storage capacity of 28,000 acre-feet. With a hydraulic height of 16 feet and a length of 300 feet, this dam plays a significant role in managing water resources in the region.
Managed by the Washington Department of Ecology, Tapps Lake Dike No 2b has a high hazard potential but is currently in satisfactory condition, as per the latest assessment in February 2018. Regular inspections are conducted, with the last one in February 2017, and an inspection frequency of every five years. Despite its age, the dam continues to meet regulatory standards, ensuring the safety of nearby communities and the environment.
Congressional District 08, Washington, represented by Kim Schrier (D), oversees Tapps Lake Dike No 2b, which is under state jurisdiction and regulation. With a drainage area of 9.7 square miles, this dam plays a critical role in water management and flood control efforts in the region. As climate change impacts continue to affect water resources, the maintenance and upkeep of structures like Tapps Lake Dike No 2b are essential for ensuring the resilience of the surrounding ecosystem.
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.

About Tapps Lake Dike No 2b
Where does the data for Tapps Lake Dike No 2b 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.
