Volunteers for the year’s first Stream Clean of Boulder Creek on Saturday, April 1 beginning at 10 a.m. are eligible for prizes (including prizes for most trash and most unique piece of trash). The fly shop reminds people to dress appropriately and also does have waders available for anyone who wants them. A FREE BBQ follows the event, including beer (21+ only). The fine folks at Rocky Mountain Anglers provide gloves, tongs and trash bags — and the rewards at the end. For more information or to sign up, call 303-447-2400.
