The monthly Greenslip program is open to all WBC members and is separate from the Big Bass Kitty. There is no preregistration. Each member may enter as many fish as they wish, and the bass must be caught in Washington on a public lake or stream with an artificial lure, witnessed, and weighed on a club-certified scale. All entries must be submitted to the Greenslip chairman by the monthly meeting following the period it was caught. The eligibility period is from general membership meeting to general membership meeting. In order to qualify for the monthly award or Big Stringer of the Year (see Annual Awards), entries must be on a greenslip.
A $5 cash award is given to the member who enters the largest bass. Perch, walleye, bluegill, and crappie can also be entered to qualify for the Grand Slam award (See Grand Slam Award). Entries submitted after the meeting following the period an entry was caught will qualify for Big Fish of the Year, Annual Certificates, and Grand Slam Award, but not for the monthly cash award. Although a memberís fish may not be the biggest fish of the month, it is still important to turn in greenslips. Certificates are handed out at the Awards Banquet for all smallmouth bass caught over four pounds, all largemouth bass caught over 5 pounds, and all submitted and qualifying Grand Slam fish. The certificates are your proof of qualification for the Grand Slam Award.
