I personally fish central Oregon (near Bend, that are) every April and have for years. Always productive are the Cascade Lakes. There is a Ton of info online about these lakes. Simply type in "cascade lakes fishing Oregon" and you will find a lot of info. But I personally fish Wickiup Reservoir, Crane Prairie Reservoir, and Odell Lake. Wickiup is just west of La Pine. Very well known and big lake. Probably best known for it's HUGE Brown Trout and Kokanee. It also has a good population of Rainbow Trout and great Large mouth Bass fishing if your into that. Bass fishing is usually best during summer. The Trout and Kokanee are good rite now! That reservoir once held the state record "26 Pound Brown Trout'. People around there (other fisherman, store owners) are very nice and are always willing to share helpful info on whats best rite now, where to go, and how to do it. That always helps.
Also, Crane Prairie which is close to Wickiup, is also a great lake to fish now - the end of summer. It also has the same main fish species of Wickiup Res. There are HUGE Rainbow's in Crane Prairie also known as "Crane-bow's". Fly fishing as well as conventional method's of fishing are both productive. Personally I target these 2 Cascade Lakes when I fish up there. I know at Crane Prairie there is a lodge on the water where you can rent a little aluminium boat with a little outboard motor for very cheap which allows you to access the entire lake. But I've fished from the bank with Power Bait and always caught fish. The preferred method is to slowly troll Rapala's or wedding rings with a worm at the hook. Also a simple can of White Corn is always deadly on both lakes. There are free camp sites all up and down the banks of both lakes. Also there are small cabins to great lodges you can rent as well. So you can still "make it special" while getting your Fish-on at the same time! Good luck if you DO end up out there, there are some BIG fish in both those lakes.
