Lakes:
Grand Lake/Shadow Mountain- Look for lakers in Grand Lake between 35-90 feet. Most active fish being found suspended near large drop-offs/humps. Jig with white/tan glitter tube jigs tipped with sucker meat. Trolling deep for lakers with nightcrawlers and spoons has been producing fish. Shadow mountain has fished well trolling/casting rapalas and tasmanian devils with the colder water temperature. Due to the heavy rains a lot of ash and debris have been coming down the inlets, but has not affected the fishing.
Lake Granby- Find the hills and jig tubes and heavy spoons, troll needlefish and flatfish around 50 feet for lakers, and Rapalas around 5-20 feet for browns and rainbows. Using electronics to find suspended fish and jigging for them specifically has produced the most bites.
Williams Fork Reservoir- Find the structure, find the fish! A jig n' rap tipped with a little bit of sucker meat has worked well. Warmer water temperatures have been pushing fish further down the water column.
