-------------------------------------------------------------------------------
In the decades following construction of the Cresta Project flows were diverted for hydropower and only 50 cfs flowed through the channel. Unscheduled spring and winter releases were erratic and impossible to catch. All this changed in June 2002 with the first recreational release, a requirement of a new hydropower license. The staff and volunteers of American Whitewater, Chico PaddleHeads, and Shasta Paddlers spent more than five years, thousands of dollars, and thousands of hours negotiating to make these recreational releases happen. Now the boating community has a great new river to enjoy.
The run starts out at the downstream side of the Elephant Butte Tunnel. From this small pull-out there is an informal trail to the river. Continuing approximately 100 yards upstream of the pull out there are ropes to guide your way down to the water. There is a good pool at the base of a rapid that emerges from the base of the dam. You can run this drop if you're willing to hike up on river left but more typically paddlers just put in at the pool below. The action on the first half of the run is generally class III/IV pool-drop. After a short warmup the river plunges through a stout hole at the base of Grizzly Dome. Below this drop Grizzly Creek comes in from river left through a tunnel carved under the highway.
The river bounces through some fun whitewater including one of the longer rapids on the run before you reach County Line Rapid. This drop is located at the Butte/Plumas County Line marked by the sign visible up above on the road on river left. This class IV drop is one of the more challenging drops on the run as much of the river funnels into a big hole at the base of the drop. There is a nice boof flake to the river right side of the hole.
After some more fun whitewater you will be at another challenging rapid, Table Rock, that starts with a move to the right and ends with a nasty undercut on river left. This is Deep Throat and it has been the site of one fatal accident and a couple of close calls. If you end up out of your boat, swim as hard as you can to the right. Below this the river plunges through another great rapid with bouncy holes.
Soon the rapids taper off as you pass the Shady Rest area. This is an alternate access site and there is a decent amount of parking here. Those who want to run laps on the best rapids upstream of this point can flag down the shuttle. Others put in here who want to run the easier rapids downstream of this point. Most just continue paddling down to the Cresta Powerhouse. The rapids from this point on are enjoyable class II/III with a couple of fun moves and decent play spots. The final boulder garden above the powerhouse can be challenging particularly at lower flows but there are a couple different options.
Logistics:
The Feather River Canyon is a short drive from most Northern California locations and a high quality resource. The take-out is located at Cresta Powerhouse, specifically at the large parking area on the downstream side of the powerhouse (with room for approximately 150 cars). The powerhouse is 47 miles south of Quincy and 36 miles north of Oroville on Highway 70. During scheduled releases please stop at the sign-in tent as future releases will be determined by use numbers. You can also load your boat on the shuttle ($5) which is highly recommended due to the absence of parking at the put-in. From the take-out the shuttle takes you north on Highway 70. You will pass Shady Rest area (an alternate access point) 2.6 miles form the take-out. At mile 3.8 you will pass County Line Rapid at the Butte/Plumas County Line. The Grizzly Dome access at mile 4.5 is a possibility as a raft launch but parking is limited due in part to the popularity of this site for climbing. The primary access is located at mile 4.8 at the west end (downstream side) of the Elephant Butte Tunnel and just downstream of the Cresta Dam. Parking at this site is prohibited during release days so the shuttle bus can access the site.

Cresta Reach Release Schedule in 2011
Wet/Normal Year
· 800 cfs between May 1 and May 7 with an additional increase to 1200 cfs for 24 hours the first weekend in May, noon Saturday until noon Sunday (May 7-8).
· Flows decrease to 600 cfs for the remainder of May (beginning after noon on May 8).
· 500 cfs for June and 400 cfs for July except during “no touch days” which will be at 325 cfs.
AW negotiated real-time flow information and works cooperatively with PG&E to provide it through a web interface (AW Feather gauge). Historical data for this reach can be obtained from the USGS NF Feather bl Grizzly Creek, Station 11404330.
Required Minimum Flows - Normal & Wet Years
| Month | Minimum Flow - cfs | |
| March & April | 250 cfs plus rise and fall from East Branch Feather | |
| May | 600 cfs + EBF | |
| June | 500 cfs + EBF | |
| July through Nov | 325 cfs | |
| Dec through Feb | 240 cfs |
Notes:
(1) Rise and fall to follow E. Branch Feather rate, to be achieved by holding Rock Creek & Cresta PHs constant
during pulse (unless Cresta PH decreased to maintain flow > target pulse). Pulse event can be terminated when
EBF flow is constant (+-100 cfs/hr), at which time normal operations resume, and spill may be reduced at 150
cfs/hr. Same rise and fall ramping limitations apply to non-pulse spill events past dam during March - first 2
weeks of June.
(3) If flows at NF56 are between 275 and 3000 cfs, Rock Creek shall be block loaded to avoid having spills start and
stop at Cresta Reservoir. (March through June)
(4) 300 cfs/hr rise during first 2 weeks of June, 400 cfs/hr rise for second 2 weeks of June if spill is from operations.
(5) Minimum monthly flow to be measured at Licensee gage NF56, and at least 100 cfs shall be released from
Cresta Diversion Dam at all times.
(6) Pulses are 12 hrs continuous duration, and no riparian flows occur.
(8) Implementation of flow in this table is automatic after first 5 years.
(9) In May, flows shall increase to 800 cfs from May 1 through May 7 with an additional increase to 1200 cfs for 24
hours the first weekend in May from noon Saturday until noon Sunday. If May 1 is a Sunday the 1200 cfs flow
shall take place starting May 7 with flows reduced to 600 cfs after noon on May 8.
(10) A boating flow of 400 cfs shall be provided throughout July except during “no touch days”, periods when the
California Independent System Operator has issued a Restricted Maintenance Operations Notice.
(11) Condition 17 study results could necessitate the cancellation or modification by the ERC and FS of the flows
