Gauge Description:

There is now a realtime gauge for this river. The information below represents the old way of checing levels:
Check it out when Bacon Creek is above 600cfs or so and Newhalem Creek is over 200 cfs . Historically there was a USGS gauge on the Cascade (stn. 12182500, 1908-1978, 172 sq. mi.). The paddler's visual gauge for the Cascade is at the Cascade- Rockport Bridge. The gauge is located immediately downstream of the bridge at the fish intake screens (photo). It is a non- traditional gauging system. However, this is what paddlers have been using for years.

  • 1.5 screens showing-low- bony in spots, but, manageable
  • 0.5 screen showing- medium-great level, a little pushy at the top
  • >6 inches over the screen-high-BIG FUN, very pushy and continuous. It would be a very long swim.

You can try contacting the Marblemount Hatchery (360-873-4241) for the water level as they clean the screens daily.

0 - 300 cfs extremely Low-somewhat Low none gauge is important or has warning Too low for a boat and too dangerous for an inner tube. Go float the Skagit instead.
300 - 700 cfs somewhat Low-barely Low III-IV gauge is important or has warning When nothing else is running and you're really desperate, there's still enough water to float this section, but expect lots of scraping. Bring your beater boat
700 -1200 cfs barely runnable-med runnable IV+ gauge is important or has warning Lower, but still good.
1200 -2000 cfs med runnable-a bit pushy runnable IV-V gauge is important or has warning Great fun level. Everything is nicely padded but not too pushy.
2000 -3500 cfs a bit pushy runnable-high runnable V gauge is important or has warning Pushy with more of a bigwater feel.
3500 -6000 cfs somewhat High-somewhat High V+ gauge is important or has warning Might be runnable, but don't know anyone who has. Expect big logs to be chasing you down stream.
6000 -50000 cfs somewhat High-extremely High none gauge is important or has warning Essentially flood stage, and not in a good way. Go run something else.

Reports give the public a chance to report on river conditions throughout the country as well as log the history of a river.
