"We removed all of the chubs in the reservoir in 2006. Even if we allow anglers to keep one cutthroat or tiger trout between 15 and 22 inches long, we think there will still be enough of them in the reservoir to keep the reservoir's chub population in check."

Wilson added the growth of the larger rainbows in the reservoir appears to be stalling at about 20 inches in length. Allowing anglers to take some fish in the 15- to 22-inch range will provide more food for the remaining fish, and that should result in more fish growing longer than 20 inches.

Anglers would not be allowed to keep tiger muskies at Newton Reservoir under another DWR proposal.

Tiger muskies are a cross between northern pike and muskellunge. Anglers commonly refer to muskellunge as "muskies."

Earlier this year, the DWR had to close Pineview Reservoir to the possession of tiger muskies. The closure will help ensure plenty of tiger muskies remain in the reservoir until a disease-free population of muskies can be found to breed with northern pike in Recapture Reservoir.

Now the biologists would also like to add Newton to the closure list.

"We're fairly confident that we have found some muskies that are disease-free," said Drew Cushing, warm water sport fisheries coordinator for the DWR. "We'll know for sure by mid-September. If the muskies are disease-free, we'll bring them to Utah and start raising our own muskies at a new hatchery in Salt Lake City. Then we'll breed them with the northern pike at Recapture Reservoir.

"Potentially, we could be stocking tiger muskies again in two to three years," Cushing said. "In the meantime, the closure at Pineview, and the one we're proposing for Newton, would keep plenty of big tiger muskies in those waters for anglers to catch and release."
