Wrangell’s annual fishing derby will close on Sept. 7 after a three-month contest to see who can land the largest king salmon, coho and halibut.

The winner in each category will receive a $1,000 cash prize.

There have not been any changes in the leaderboard for kings and halibut in more than two weeks, but Dave Mork has moved to the top of the coho board with a 10.1-pound catch, said Greg Clark, a board member with the chamber of commerce, which runs the derby.

As of Aug. 17, the leaders were:

King salmon: Diana Nore-Ellison, 27.9 pounds; Jody Clark, 27.7; and Marlin Benedict, 23.2.

Halibut: Bristol Wagner, of Cherry Valley, California, 133.6 pounds; Jeff Murtaugh, of Arizona, 111.2; and Charlie Wagner, also of Cherry Valley, 87.4.

Coho: Mork was in first, at 10.1 pounds, followed by Diana Nore-Ellision, with a 6.7-pound catch.

Mork won the “hidden-weight” prize of $300 for his Bearfest weekend coho, Clark said, coming closest to the computer-generated secret weight for a coho caught Aug. 8-9. The secret weight was 18.2 pounds.

No one entered a halibut over Bearfest weekend, which means there was no hidden-weight winner in that category.

The last hidden-weight contest will be Labor Day weekend, Sept. 5-7, the final days of the derby.

Derby tickets, at $35 each, are available at Sentry Hardware, the Stikine Inn, Alaska Vistas, Angerman’s, TK’s Mini Mart and the chamber office in the Nolan Center.

The weekday weigh-in station for derby entries is at Peninsula Seafoods at the Marine Service Center.

Boaters who bring in catches evenings and weekends can go to a weigh-in scale at Reliance Harbor, across from the harbormaster’s office, and weigh in their catch and take a photo, Clark explained. They can send the photo to 907-660-7092, or call the number to see if someone with the chamber could meet them at the weigh-in station.
