Directions: From Fresno, go 63 miles northeast to the town of Shaver Lake.
Turn east on Dinky Creek Road and go 12 miles. Then turn right on McKinley Grove Road and go 14 miles east.
The road forks with Courtright going 10 miles north and Wishon going 3 miles east.
Wishon and Courtright are reservoirs owned by PG&E, constructed in 1958 using rock filled dams. Wishon is at
an elevation of 6560 feet and has a capacity for 128,00 acre feet. Courtright is at an elevation of 8,192
feet and has a capacity for 123,000 feet. The primary need for the reservoirs is to supply hydroelectric
power. Since power needs fluctuate from night to day, PG&E has found it economically feasible to use
the two reservoirs in unison so that they allow water to flow to the lower reservoir during the day and
create higher priced electricity. Then they use the lower cost of electricity at night to pump the water
back up into the higher Courtright Reservoir. Thus the levels of the two reservoirs fluctuate greatly on
a daily basis. Needless to say, this creates great havoc for the resident fish. The two reservoirs are
stocked with about 20,000 10-12 inch Rainbows each year. Holdovers can range from
16 to 18 inches with the Lake Record being 7 Lbs. 3 oz. at Courtright and 20 Lbs. 11 oz at Washon. There
are Browns in the lakes but the numbers caught have greatly reduced over the years.
Wishon is your best bet for Browns in the 10-15 inch class. Float tubing on Courtright has access at the
ramp near Marmot CG and near the dam on Wishon. At Courtright, try the dropoffs along the eastern shoreline
and along the dam. At Wishon, work the south side of the dam and along the northern shoreline. Mosquitos
are plentiful in this area, so bring plenty of repellant. Callibaetis hatches occur during the early evening
hours, particularly within the inlets for dry fly action. Even though the fishing season is open year round ,
the road access is closed from mid-November until May due to snow conditions.
The two reservoirs make great stops for flyfishing opportunities into the backcountry. Courtright has
access into the John Muir Wilderness and Upper North Fork Kings from the Maxson Trailhead or Voyager CG
on the northeast side. You can also access the Dinky Lakes Wilderness along Helms Creek from the Cliff
Wishon Reservoir gives you access into the Woodchuck Country and John Muir Wilderness. You can also try
the North Fork Kings below the dam.
