About this reservoir

Onondaga Lake At Liverpool Ny

Onondaga Lake, located in Liverpool, New York, has a rich history dating back to the Native American Onondaga tribe. The lake is an important part of the regional hydrology and receives surface water flows from numerous creeks and streams, including Ninemile Creek and Ley Creek. Snowpack contributes to the lake's water resources during winter months. Historically, the lake has been heavily polluted due to industrial waste and poor sewage management, leading to the formation of a Superfund site. However, recent efforts to clean up the lake have been successful, leading to improvements in water quality and increased recreational uses such as fishing and boating. The lake also supports local agriculture through irrigation and provides a habitat for wildlife.

FAQ

About Onondaga Lake At Liverpool Ny

Where does the data for Onondaga Lake At Liverpool Ny 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.
