Howard A Hanson Reservoir Near Palmer reservoir
Howard A Hanson Reservoir Near Palmer
Howard A Hanson Reservoir, located in Washington State near Palmer, is a large water storage reservoir that was constructed in the 1960s for flood control, water supply, and hydroelectric power generation. The reservoir is fed by several major creeks and rivers, including the Green River and its tributaries. The surface flow of the reservoir is primarily from the Green River, which provides over 80% of the water volume. The reservoir also receives water from snowpack, which contributes to the reservoir's water levels during the spring and early summer. The reservoir has been used for agricultural irrigation and recreation, including fishing, boating, and camping. However, in recent years, the reservoir has faced problems with sediment buildup, water quality issues, and potential dam safety concerns.

About Howard A Hanson Reservoir Near Palmer
Where does the data for Howard A Hanson Reservoir Near Palmer come from?
Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.
What does the Hazard 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 reservoir, set a threshold, and you'll get a push the moment conditions cross.
