Trolling for lake trout

Freshwater folks,

I'm more of a saltwater fisherman, but next weekend I have an opportunity to head out to Lake Crowley in the east Sierras. I want to troll for trout. My only experience with salminids is accidentally hooking up on a coho on a sabiki in HMB.

Since the weather is hot, I'm hoping to catch one or two legal (>18") rainbows or browns for dinner and not stress out a bunch of smaller fish with C&R.

I have a variety of lures and some vintage hardware available. I'm hoping to get some advice what would be effective. I've been reading up and watching videos, and it looks like the spoons / spinners are good (I'll add an egg or inline weight to get them down in the water column), but they seem quite small to catch a big fish. Would the flatfish, minnow, or kastmaster be more selective for bigger fish? I'm curious what others would bring and prioritize trying.

Also, is the dodger / flasher setup worth adding? I have seen them recommended for trout and kokanee, but I feel like it's a lot of hardware / commotion for fish that are supposed to be line shy.

I'll have some time to try different things, but I want to make sure I've at least got a sensible approach.

fwiw
I am a rookie that didn't really start fishing much till I retired.
There are hard core guys with the knowledge here that will hopefully chime in soon.

When they locked out Hennessy ( which had limited trout action) our muni h2o supply due to new muscles
I switched to Berryessa and studying the prospects I saw lots of "Salmonid" action so I searched the gear, ended up with 2 lake troll setups along with 2 dodger setups, and a few deep diver sizes,  then I got on the largemouth bite and have not spent any time on trout.

Couldn't hurt to run them, I have trolled flatfish for good effect in the past.
I caught a 20- 25 inch rainbow in buck island lake on a roostertail the same size as the meps in the upper corners of pic 1
 

I'd say you can fish everything from the double-jointed lure on up for trout.  But my top three would be the kastmaster, the straight lure, and the double jointed. The other spinners can work but you will want to use some weight and either a rudder or some bead chain swivels to counter act line twist. The bottom right blade looks like a Ford Fender and you can troll it with a night crawler pretty effectively but with a lot of drag. Dodger and lure/bait is a good method for trolling larger lakes to me because fish can see it from farther away.

Some of the spoons you have are relatively close to a Thomas buoyant.

I wonder how deep they’ll be this time of year. You might want to get some clip on weights to get down deeper if necessary.

The flatfish has worked for me before. If fish are in the top 20' then maybe just long line it - 70' to 100' back, but otherwise try a 2 oz or 3 oz sinker on a slider ahead of a swivel clip and then about 3' of line to the lure. There are depth charts based on sinker weight and line out, but I would probably let out 40' to 70' of line with that if they are deeper.

Thanks all for your advice!

Went out on Lake Crowley, but unfortunately the algae had taken over. The water looked like soup. I tried the spinner, minnow jerkbait, and kastmaster, but only got weeds. I didn't even attempt to use the flasher setup with the water conditions. After unsuccessfully attempting to troll, I ended up posting up in a shallower bay and tossed a spoon and a curly-tail grub jig without success. I had a nice time out on the water but no fish.

The following day I went for a hike to some alpine lakes with my wife and didn't bring any gear. Of course, the trout were everywhere, including right along the shore. I got a nice photo of a brook trout cruising the shallows. Next time I know for mid to late summer to stick with the colder lakes.

Anyway, back to saltwater for me (until next time).
