What to Expect in May
Some of the coastal lakes, such as Cape Meares Lake near Tillamook have stocked trout and are worth casting to in May.
By the end of the month, the smallmouth bass in the mainstem of the Umpqua should be done with their spawning and ready to smack a fly, unless the flows are too high and cold.
Shad will be available in the Umpqua.
Some of the coastal lakes, such as Eel Lake near Coos Bay, have stocked trout and are worth casting to in May.
Coastal bass lakes such as Tenmile and Siltcoos should be good for largemouth bass.
It will soon be time to think about smallmouth bass on the John Day river.
Howard Prairie and Hyatt lakes are late month possibilities. These lakes are between Klamath Falls and Ashland. Trout fishing can be good at times, but a cool spring will result in a slow start.
Early season fishing for stocked rainbows can been good in South Twin and North Twin lakes. Both lakes are very deep, so just fish the first 50 feet near shore. These lakes are options when the wind blows you off other lakes. Size 10 olive Woolly Buggers and size 14-16 Flashback Pheasant Tails are good flies to use. Present them with an intermediate line and a 9-12 foot 5X leader.
Laurence Lake near Hood River can be good for anglers who present small Woolly Buggers with a slow retrieve near the surface. Illegally-planted bass are in the lake, although they are not plentiful. If you catch one, take it home and fillet it for dinner.
Shad should be available in the Willamette River around mid-month. Fly fishing for them can be productive if the river level is not too high.
