New Hogan Lake reservoir
New Hogan Lake
New Hogan Lake is a reservoir located in Calaveras County, California. The lake was created in 1963 by the construction of the New Hogan Dam, which was built as a part of the Central Valley Project. The lake is primarily used for irrigation, flood control, and recreation purposes. It has a capacity of 337,000 acre-feet and covers an area of 4,400 acres. The hydrology of the lake is mainly attributed to the Calaveras River and the Bear Creek watersheds. Surface flow from these watersheds feeds the lake, as well as the snowpack during winter. The water from the lake is used for agricultural purposes in the surrounding area. The lake also provides recreational activities like hiking, fishing, camping, and boating.

About New Hogan Lake
Where does the data for New Hogan Lake 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.
