Granby Lake has developed enough ice to attract a good numbers of anglers, many on snowmobiles. Ice thicknesses have been reported from 4 inches (sketchy for sleds) to 8 inches or more. Expect the ice to be growing a couple of inches per week, provided snow remains light. The thicker ice will be found in shallower areas, such as Arapahoe Bay. Catching reports have been mixed. Shallow waters are producing rainbows and an occasional small lake trout. A wide variety of baits are working. Most anglers are fishing deeper waters, as deep as 80 feet, for lake trout. Jigs 2 inches and larger tipped with a strip of sucker is the typical approach. A 30-inch fish was reported last week.
If things are slow, consider fishing nearby Willow Creek for some fast trout action. Just don’t expect much in the way of size.
Green Mountain Reservoir is another popular lake trout water. It has a cap of ice 9 inches or better over most the lake. As with most reservoirs this time of year, reports are mixed; some are doing well, others not so much. The one constant is that successful anglers keep moving and trying different tactics. Depth also seems to matter right now, with decent numbers coming from 40 to 50 feet of water. White tube jigs in the 3- to 4-inch classes have been effective.
Williams Fork Reservoir is known for lake trout, but it also has a population of northern pike. Working shallow water is the better bet if pike are your targets. Jigging spoons, suckers, tubes and larger ice jigs are good choices. Consider fishing for trout, and if action slows or dies quickly, suspect a northern and switch tactics. Fish deeper waters with tactics mentioned above for lake trout.
Nearby Dillon Reservoir has slowed in the inlet areas. Better action will be had by fishing near shore in areas that don’t look like Swiss cheese.
South Park waters continue to draw crowds, and fish can still be had. As with most heavily fished water, fishing the lower trafficked areas and trying different strategies will produce better results. Also, soft-tipped rods and a little movement every now and then with the line will help.
Antero Reservoir has been fair the past week. Look for weeds and work the edges. Shallow waters are also working.
No matter the depth, be sure to work your lures from the ice down to the bottom. Stay a few seconds at each level. Eleven Mile Reservoir has been generally slow but continues to produce some decent-sized fish for those willing to put in the time.
