Absolutely, The trout regulations come first and govern the stream. All hatchery Supported water is closed during March, but you can fish for Smallmouth in the Delayed Harvest sections as long as you use Single hook(not a single treble, a single hook point), artificial only (no chemically enhanced, NO Powerbait, Maxscent, Gulp, or spray on attractant, etc) lures or flies. When Hatchery Supported reopens on the 1st Saturday in April it is fair game for any artificial and most natural baits. Check the regulations regarding minnows and helgramites.
