"Hooked On Fishing" Opening Day Trout Derby on Lake Wilderness - April 27-28, 2018

The Greater Maple Valley - Black Diamond Chamber of Commerce, in partnership with Maple Valley Rotary and the City of Maple Valley, presents the 16th annual celebration of "Hooked On Fishing" Opening Day Trout Season on Lake Wilderness! The fun begins at 3pm on Friday afternoon with tent camping in Lake Wilderness Park. The fishing derby and Rotary breakfast begin at 12:01am (MIDNIGHT - that's right!) concluding at noon on Saturday.

The event includes the trout derby with prizes for almost everyone (derby ticket $2) and the tagged fish derby ($5 ticket must be purchased prior to midnight on Friday). Fish school for young anglers 9 and under opens at 6am on the dock. Maple Valley Rotary also fires up the grill for hamburgers and hot dogs at 5pm Friday night.

For this once a year event, the City is allowing limited overnight tent camping in The Park for derby participants only. (NO RV's -parking is limited to one space per participant! Additional boat trailer parking will be available at the Maple Valley Community Center) Campers will be able to register and set up campsites beginning at 3pm on Friday evening.

Please note that Derby Headquarters/Weigh Station/Rotary Food Stand/Camping Registration will be in a different location due to construction on new Beach House.
