Ice Fishing For Burbot

Numerous burbot ice fishing tournaments have been held on Flaming Gorge Reservoir in recent years. Beyond the large numbers of fish removed at each of these derbies it is striking how many participants struggle to catch burbot. A few teams consistently catch large numbers of burbot, another group of teams catch some, but a lot of teams catch very few. This article shares some tips for catching burbot through the ice on Flaming Gorge Reservoir in hopes of increasing catch rates on these voracious predators. Remember, every burbot removed from Flaming Gorge Reservoir represents a savings in game fish, especially kokanee and smallmouth bass! Burbot are most active at night. In Flaming Gorge, they find dark recesses under rocks and in holes and cracks in the rocky cliffs that line the reservoir. Around sunset, burbot start emerging from hiding and looking for food. The first 2-3 hours following sunset and the couple hours before sunrise can be very productive periods for catching burbot. Good burbot fishing can be found immediately adjacent to cliffs both on the main body of the reservoir and within the bigger bays of the reservoir. The deep vertical habitat immediately next to most cliffs tends to produce few burbot. Instead

anglers should target the habitats adjacent to cliffs with slopes less than 70 degrees and a rocky bottom. The mouths of bays tucked between cliff complexes can be also good. Other good spots to try are cliff complexes within bays that have gradually- sloped habitat nearby. Burbot can be caught at water depths of 5 feet out to 70 feet, but 20 to 30 feet is most productive. Lures should be no more than 6 inches off the bottom. If you are fishing with multiple lines, spread them across a range of depths to start and consoli- date them near the depth that is working best. If you are not catching fish, move to new holes regularly. Night fishing for burbot requires lures that glow. Jigs with luminescent grub bodies and heavy spoons that are luminescent are most productive. The weight of lure used will be dictated by the depth you are fishing. If you are fishing shallow ¼ or 3/8 ounce jigs are fine. If you are fishing 40 feet or deeper you will need a ½ ounce jig or more. Burbot are not shy and don’t care about the lure’s weight so use the lure that gets you down fast. Also keep in mind burbot have hard mouths and Pa ge 4 Green River Region Angler Newsletter V olume 7

The Three Species—Native non-game fish of the Green River

Flannelmouth sucker, bluehead sucker and roundtail chub, collectively known as “the three species” are native, non-game species of the Colorado River drainage. The Green River drainage in Wyoming is the northern most extent of their distribution. Once abun- dant in rivers of Wyoming the three species have experience severe declines in recent dec- ades. Although many factors have contrib- uted to the decline of the three species intro- duced non-native fish species has had the greatest impacted. Three non-native non- game species in particular have contributed to the decline of the three species: white sucker, burbot and creek chub. White sucker pose the biggest threat to the native suckers by competing for food and readily hybridizing with the native suckers. Burbot, as they spread throughout the Green River drainage, are taking their toll on the native fish by prey- ing on them. Creek chub compete with roundtail chub for food and habitat. Adult creek chub have also been found to eat the fry and juvenile life stages of the native fish. The WGFD has been working in three drain- ages to reduce the threat posed by these non- native fish. Crews from the WGFD has been electrofishing many miles of river and stream habitat in the Big Sandy and Little Sandy drainages and the Muddy Creek drainage to remove non-native fish species. In 2011 175 miles were electrofishing across the three target drainages. Pa ge 5 Green River Region Angler Newsletter V olume 7

Green River Float Map

We often field calls from anglers asking about boat, shore and wade fishing access points and camp grounds along the Green River below Fontenelle Dam. The next two page insert is a float map with improved and unimproved boat ramps, approved camping lo- cations and legal status of lands from the Fontenelle dam down to the “six mile” boat ramp (I) downstream of the confluence of the Big Sandy with the Green River. River and road mile distances between landmarks are given in a table on page 5 for ease of naviga- tion. Please note that the Green River from the CCC bridge (near Slate Creek Camp Ground; C), downstream to the Big Sandy confluence is a special regulations area. This area has a creel limit of one trout per day or in possession. All trout under 20 inches need to be released. Also, fishing is permitted by artificial flies and lures only throughout this section. Use of bait is allowed upstream and downstream of this area and state-wide creel limits apply. Please check fishing regulations prior to going out for special and seasonal regulations. Green River Float Map

Fontenelle Boat Ramp Upgrade

The Wyoming Game and Fish Department used Boating Access monies to upgrade the boat ramp on Fontenelle Reservoir near the Dam. Construction occurred in November and December of 2011. Thermal blankets and a lot of elbow grease were used to com- plete construction during a window of good weather. The project included extending the concrete portion of the existing boat ramp up the hill to just shy of the outhouses. This project has thankfully eliminated the long-standing problem of vehicles skidding out on the steep, gravel of the old ramp. But don’t take our word for it. Get the boat out and go see for yourself!
