We’re about to get a lot of rain, and like every year I get interested in the local rivers and waterflow around Grass Valley, CA in Nevada County. Here’s some rough notes and resources.
Yuba River, particularly the South Fork
- Yuba River at Marysville: flow history and forecast. This is below Englebright Dam, so includes the choices of how much water they’re releasing there. But is excellent data from NOAA.
- South Yuba at Highway 49: flow history, forecast. From Dreamflows.
- Yuba River at Jones Bar: flow history. From CDEC. This is either the exact same sensor Dreamflows is showing at Highway 49 or else is a mile downstream.
- Yuba River flow history along the whole river. This is California state data (CDEC) and the website has lots of neat stuff.
- Watershed map
- Wild and Scenic River Act protects the river from Lang Crossing to Bridgeport. This is the much loved stretch of scenic river with lots of swimming holes, etc.
- BLM management plan
Deer Creek in Nevada County
- Deer Creek at Smartsville: flow history (alternate). This location is below the dam at Lake Wildwood.
- Sierra Streams Institute, a very professional looking site about Deer Creek including a map of monitoring sites. Unfortunately no data is online and it looks like the site last was updated in 2013. The Facebook page is quite active though.
- I couldn’t find anything about Deer Creek on the CDEC site.
- Deer Creek is literally 500 feet from my house and, fortunately, 100+ feet below it. I can hear it rushing all the time, but have to hike/drive to see it.
This ArcGIS map of World Hydro Reference Overlay does a good job showing labelled rivers against towns and major roads.
