Smaller Fish6-12Fish streamers (e.g. ‘Black Ghost’, ‘Gray Ghost’) and bucktails (e.g. ‘Mickey Finn’, ‘Black Nosed Dace’) year round but especially late fall – early spring, when waters are high and not much is hatching. Or try fishing large and/or weighted streamers such as zonkers, matukas and sculpins very early in the morning or right after a major storm when targeting large predatory trout.

~~~

Please fish for trout only when the water temperature is ≤ 66º F – which means
tailwaters only in summer. ~ Use 
de-barbed hooks, and reel in the fish quickly,
always keeping it in the 
water and not holding it with dry hands.
