Check on page 337 of the Washington State Fishing Guide (8th edition). It lists around two dozen alpine lakes that have been stocked with golden trout. Among those, about half a dozen are in King Co. Most of these lakes are off the beaten path and "off-trail" hiking knowledge is useful.
Here's a pic of a golden from a high lake that's less than 50 miles from downtown Seattle. Most lakes that have been planted with goldens are quite remote. Reaching them requires specialized gear and off-trail experience as well as many calories. Despite the barrier to getting to them, it's quite unlikely that anybody with firsthand knowledge is gonna name one in an open forum this size.
the goldens were all originally from the Kern river drainage in the Sierra mtns of California. They were then stocked in several other states but did not always survive or sustain themselves. However in the rockies they did even better than their home state. If I remember correctly the record fish is from Colorado. They are always found above 10,000 ft.in the sierras and not very plentiful. they were stocked in many lakes there but that was stopped and they have dissappeared from many of those. My son took me on a trip there in 07 and we cought only beautiful brookies and we were over 11,000 ft at the 4 lakes we fished. However the trip was great anyaway. good luck finding the goldens. Bob
Another way to find golden trout lakes is check out the WDFW site, find the fry stocking page and see which lakes are getting goldens. Check the stocking for a couple years back to get an idea which ones might have bigger than fry sized trout and leg it on in to the lakes.
One thing I love about flyfishing for Goldens is the habitat they thrive in. I've fished for them in theSierras, the Beartooths and the Winds. In every case that's meant difficult hikes through some of this country's most wild and remote places. Anyone who develops this addiction woud do well to buy Rich Osthoff's book Flyfishing the Rocky Mountain Backcountry and study it thoroughly.
Here's a Golden I caught on my last trek for them. It involved a 70 mile round trip hike over two passes. Worth it? Every minute!
I'm liking this thread...I've been reading through it and didn't realize goldens were planted in some alpine lakes myself...I did hear they were in the Northeastern corner of the state, natural though...Thats a fish I'd like to try and catch....Just another trout species to check off my list...
I saw that WDFW dumped about 2000 golden fry into Edds lake a couple years ago. I am currently planning my ascent and descent into the lake area. As far as I am concerned this is going to be the coolest hike ever, and don't worry ABSOLUTELY nothing but catch and release with barbless hooks.
