Directions: The Kings River can be reached from Fresno by way of Hwy 180. Trimmer Springs Road will take you up to the town of Piedra, below Pine Flat Reservoir. Following this road around you can get access to the North Fork of the Kings and also access to the 20 mile long Wild Trout Section above Garnet Dyke on the Main Kings up to Boyden Cave.
The Kings River above Pine Flat Reservoir is a wild trout only water. All plantings by DFG are below Pine Flat Reservoir. The season is year-round. The section of the Kings above Pine Flat Reservoir, along Trimmer Springs Road up to Garnet Dike Camp is worth investigating. There are a lot of big fish hanging out in the riffles, holes and long tail-outs that are characteristic of the water in this area. This area has a 2- trout limit with no restrictions on tackle. The entire length of 20 miles from Garnet Dike Campground to the confluence of the Middle and South Fork of the Kings is a designated Wild Trout area Catch and Release only with barbless flies. You can follow the riverbank or follow a trail upstream from the campground. The trail will reach a higher elevation above the river making access difficult for about 1 mile. Then it drops down to the river.
During the Winter, the Kings can be so cold that the fish are lethargic. However, the flows are low so wading is possible. Midges are the preferred food source at this time. Starting in late February, a good BWO hatch occurs in size #18-20. The better fishing usually starts in early Spring just before the snow starts to melt. If there is an early warm spell, the river will result in a high runoff and fishing will be on hold until the water levels come down and warms up. March brings Golden Stoneflies, so try using #10-12 Kaufmann Stoneflies in tan or mottled black and brown. March can also bring a nice hatch of March Browns. Caddis flies will be present in April. Try using a CDC Cripple, a #12 reddish-brown Parachute Hares Ear, or a Comparadun.
When there are late periods of runoff, the Kings River might not be fishable until mid-June. A combination of Golden Stonefly Nymphs and a size #12-14 dropper of a Prince Nymph, Hare's Ear, or Pheasant Tail will help get the rig down into the deeper reaches of the river. As the river further drops, try attractor dries, such as an Orange Stimulator (#8-10) or a Parachute Adams (#12-16).
A spotted caddis hatch occurs in September, use a Kings River Caddis, size 12-14. Try the pocket water and micro-eddies near shore. Concentrate on water that is 3-4 feet deep. Survey results from the State of California show that most of the fish within the Upper Kings above Garnet Dike are Rainbows in the 14-15 inch class with larger Browns in the the 18-20 inch class. About three miles upstream from Garnet Dike campground the river is within a canyon up to Boyden Cave, just upstream from the confluence of the MF and SF Kings. This is a 7 mile stretch of water with little access. Highway 180 provides access at Boyden Cave but you can also take the trail out from Yucca Point.
Flows can vary depending upon snowmelt and rain runoff. Usually the flows are less than 1000 cfs. Safe wading conditions are generally below 500 cfs. Check the link above for Current conditions.
