This comes from the Wyoming Department of Fish and Game:
GREEN RIVER-The Wyoming Game and Fish Department is reminding anglers about the fishing closure in place to protect fish on the Green River below Fontenelle Dam. This closure has been in place for many years to protect trout and kokanee salmon spawning in that stretch of the river. The first mile of the river from Fontenelle Dam to the cable crossing just above Weeping Rock Campground is closed from October 1 through December 31.
Kemmerer Game Warden Chris Baird said he has observed a very high fishing violation rate on the Green River below Fontenelle Reservoir. “We have had fairly nice weather and continued good fishing these past several weeks and that has been part of the reason for the higher rate of fishing violations on the river,” Baird said. “I have fielded much more than the average volume of calls reporting violations of the closure the last couple years.” Unfortunately, some of these violators were reportedly very disrespectful to parties informing them of the closure and said that they are not keeping any fish so the violation doesn't really matter. They totally missed the point of the fishing closure and its purpose to protect the trout they are harming by fishing in these crucial spawning areas. Several parties have been from our neighboring states, but many have included Wyoming residents violating the closure.”
