SeilerBird said:Yellowstone Lake is overrun with Lake Trout and they are decimating the local populations. So there is no limit on Lake Trout. In the words of a ranger "Fill your freezer".
Great Horned Owl said:And, if you want more variety, there are a lot of little lakes in the Beartooth range. Many of them are strung out along hwy. 212 from the NE entrance of Yellowstone to Redlodge, Mt. This is 60 miles of some of the most spectacular scenery in the country. The road hits almost 11,000 ft. and the curves are tight, but there are no real steep grades. A stop along the way at the Top of the World Store is worth while.
There are several National Forest campgrounds along the route. Fox Creek c.g. has electric hookups, but all of the rest are dry camping.
On the way through Cooke City, stop in the Cooke City store and pick up a map of the Beartooth. There are several available, but one of them lists the species of trout in each of the lakes. On the way back, the Cooke City Cafe has great food and a beer list that runs to several pages.
Marsha/CA said:Hebgan Lake is very nice and there are a couple of campgrounds nearby. The Yellowstone area is known for flyfishing and trout. However, Hebgen Lake is very good with a lot of variety of fish. Here is a good website: http://www.westyellowstonenet.com/lakes_rivers_falls/hebgen_lake.php
Also Cliff and Wade Lake is east of the Madison River south of Ennis, MT. It has a variety of fish. You can find info on the above website. There is also a dry camping campground that is very nice at Wade Lake, not so much at Cliff. Wade has some sites right on the water and is a beautiful lake. It is first come first serve. They also have cabins available.
We love that area and will be up there sometime this summer.
