About this reservoir

Whetstone Rn Nr Mannington

Whetstone Run is a small stream located in Mannington, West Virginia. Its history dates back to the early 1900s when it was used for agricultural purposes, including irrigation and watering livestock. Hydrologically, Whetstone Run is a tributary of Buffalo Creek, which eventually empties into the Monongahela River. The stream is fed by specific surface flows and snowpack during the winter months. The surrounding area is primarily agricultural, with some recreational activities such as fishing and hiking. In recent years, there have been concerns about water quality due to increased pollution from nearby mining and drilling operations. Efforts have been made to monitor and improve the stream's condition, including the installation of water treatment facilities.

FAQ

About Whetstone Rn Nr Mannington

Where does the data for Whetstone Rn Nr Mannington 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.
