About this reservoir

Clear Lk A Lakeport Ca

Clear Lake is a natural freshwater lake situated in Lake County, California. It is the largest natural lake in the state, covering an area of 68 square miles. The lake has a rich history and was known as "Lypoyomi" by the Pomo Native Americans who lived in the area. The hydrology of the lake is unique, with no visible outflow and a high level of evaporation. The surface flow of the lake is provided by Cache Creek, while the snowpack from surrounding mountains contributes to its water level. The lake is also used for agricultural purposes, with vineyards and orchards surrounding its shores. Recreation activities on the lake include fishing, boating, and water sports. However, in recent years, the lake has been affected by toxic algae blooms, which have impacted its recreational and agricultural uses.

FAQ

About Clear Lk A Lakeport Ca

Where does the data for Clear Lk A Lakeport Ca 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).
