Local stream flows: Yuba and Deer Creek

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

This ArcGIS map of World Hydro Reference Overlay does a good job showing labelled rivers against towns and major roads.
