Loomis, I have 3 places you could try for trout and 1 for steelhead. The steelhead spot is not within 100 miles though. Currently it's really the only decent place to go in eastern Washington and your looking at about 160 miles and about 2.5 hours from downtown Spokane. The Grande Ronde is really hot in March but it is a bit of a drive. I'll assume that you want to stay closer to town, unless you let me know otherwise. The two spots for lake fishing include the mouth of the Spokane river (Ft. Spokane) near Lake Roosevelt(1.5hr) for trout or walleye from shore. There is great bank access but it is usually a bait fishery however, I'm sure that lures might prove effective. The other lake is "4th of July" lake, just south of Sprague Lake off highway 90. Your looking at about 45min-1hr from downtown Spokane. There is good bank access from this lake however it might be a bit crowded on the weekends. The lake bottom tends to be a bit weedy also. My last suggestion would include the spokane river right near downtown. Only hatchery trout (fin-clipped) may be kept, however it is a nice river to fish regardless if the water is in good shape. One year I came across a guy who had hooked two 5# rainbows with orange powerbait just a few miles downstream from town. I checked the regs and they are all open right now. If you are going to fish the Spokane river let me know so I can explain what section is open. Let me know if you prefer lake or river fishing, and I could narrow it down between the three. Also let me know when you are heading over. I might be up in Spokane this weekend. Bigdawg
