Frequently Asked Questions

How many public stream gauges does Waderly index in California?

Waderly currently indexes 781 public USGS stream gauges in California. Examples on this page include 003s001e06m002s, 003s001e06m003s, 003s001e06m004s.

What can I find on the California stream gauges page?

This state hub links to every indexed Waderly gauge page in California, so you can jump from a statewide view into current flow, gauge height, water temperature, and weather for individual rivers and creeks.

Why use the California state hub instead of searching one river at a time?

The California hub is a crawlable index of the full state network. It makes it easier to compare nearby waters, discover smaller creeks you may not search by name, and reach every gauge page from one place.

Waderly supports public stream gauges across all 50 states. This California page includes the full state index, so search engines and users can reach every gauge from one crawlable hub.

These pages are built from the public USGS stream-gauge network and linked into Waderly's map so anglers, paddlers, and waders can move from a broad state view into specific rivers quickly.
