About this reservoir

Wrightsville Detention Reservoir @ Wrightsville Vt

Wrightsville Detention Reservoir is located in Wrightsville, Vermont, and was constructed in 1935 as a flood control measure on the North Branch of the Winooski River. The reservoir has a storage capacity of 2.2 billion gallons, and during periods of high flow, the water is released to reduce flooding downstream. The reservoir is fed primarily by surface flow from the surrounding hills and by winter snowpack.

The reservoir is also used for agricultural purposes, with the water used for irrigation in the surrounding fields. Additionally, the reservoir provides a recreational resource, with opportunities for boating, fishing, and hiking. The reservoir and surrounding land are managed by the Vermont Department of Forests, Parks, and Recreation.

FAQ

About Wrightsville Detention Reservoir @ Wrightsville Vt

Where does the data for Wrightsville Detention Reservoir @ Wrightsville Vt 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).
