Stable water conditions with fish comming on spawn( Brown's & bulls) and others putting on weight for winter. combined with movement to winter holding waters .
Also insect activities slow a little making hatch id a little easier. Most importantly imo bait fish will rank higher and higher as a food source as time passes. My take on the most wonderful time in the open water calendar.
now I just hope to get some time off to enjoy a few new/full moons.
