About this reservoir

O'Shaughnessy Reservoir Near Dublin Oh

O'Shaughnessy Reservoir is located near Dublin, Ohio and was created in the 1920s to provide drinking water for the city of Columbus. The reservoir is fed by several creeks and streams, including the Scioto River. It has a surface area of 1,150 acres and a maximum depth of 45 feet. The reservoir is primarily used for drinking water, but it also serves as a recreational area for fishing, boating, and hiking. O'Shaughnessy Reservoir is also an important source of water for agricultural uses in the surrounding area. The hydrology of the reservoir is affected by snowpack providers, with snowmelt from the nearby hills contributing to the water levels in the reservoir during the spring months. The management of O'Shaughnessy Reservoir is overseen by the Columbus Department of Public Utilities.

FAQ

About O'Shaughnessy Reservoir Near Dublin Oh

Where does the data for O'Shaughnessy Reservoir Near Dublin Oh 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.
