Soulajule Dam reservoir
Soulajule Dam
Soulajule Dam is a small earthen dam located in Marin County, California, that was constructed in 1964. It is situated on the San Geronimo Creek, a tributary of Lagunitas Creek, which flows into Tomales Bay. The dam provides water for agricultural purposes and is operated by the Marin Municipal Water District. The hydrology of the area is influenced by both surface flow and snowpack, with the dam playing a role in regulating water flow during both wet and dry seasons. The area surrounding the dam is used for agriculture, including dairy farms and vineyards, and is also popular for recreational activities such as hiking and fishing. The dam and surrounding area are managed by the Marin Municipal Water District and the Marin County Parks department.

About Soulajule Dam
Where does the data for Soulajule Dam 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.
