From Sacramento drive north on Highway 99 to the town of Chico. Once reaching Chico, exit onto Hwy 32 toward Chester and proceed 40 miles east on Hwy 32 to the "Red Bridge." A small parking area is available on the north-side of the bridge (just after you cross the bridge).
Deer Creek (Lassen National Forest / Ishi Wilderness)
The headwaters of Deer Creek form out of the Southern Cascades, just north of the Mountain Meadows area. The Ishi Wilderness covers 41,840 acres and is bordered by Mill Creek Canyon in the north and Deer Creek Canyon in the south.
In reality a small river, Deer Creek is probably best known as one of the last streams in the northern Sierra that still supports threatened spring run chinook salmon and winter steelhead. Most other Sierra rivers have been blocked by dams, but Deer Creek, and a handful of other Sacramento River tributaries (Battle Creek, Antelope Creek, Mill Creek, Big Chico Creek, and Butte Creek) still provides habitat for these migrating fish.
The spring-run population in Deer Creek is one of only three or four remaining naturally spawning spring-run chinook populations in California which can be considered genetically intact and demographically viable (DFG 1990) -- two other such populations with the Central Valley drainage being in Mill and Butte Creeks.
Besides providing critical spawning and rearing habitat for native salmon and trout, the Deer Creek watershed is also essential winter range for portions of the Tehama deer herd and many other species of wildlife. Migratory birds and wintering raptors also take advantage of the pristine condition of the creek and surrounding areas.
The volcanic past of the Ishi Wilderness is evident in the numerous basalt formations which line the canyons here. Most of the formations are pinnacles of hardened lava. The most dramatic of these formations can be seem in Deer Creek Canyon. As you hike/fish along Deer Creek remember to look up and the canyon will reveal these features.
The Last Retreat of 5 Yahi Indians on Deer Creek
There were, it is believed, only five Yahi left to make the withdrawal from Mill Creek to Deer Creek, each step of which was a surrender of another piece of heartland, of oak stand, meadow land, fishing place, and upland hunting ground. There remained to them when they at last put down their baskets only two separate but closely adjacent tracts of land on the south side of Deer Creek Canyon, which they might with some reason call their own and occupy with relative security.
