While fly fishing this past Tuesday in Ryan Creek on Smith Lake, I noticed the bite slowed after 10 o'clock. I also saw that the fish still interested in my poppers were extremely scattered. In other words, I was fishing a lot of dead water, which is water with basically no fish, with the exception of a few tiny bluegills in the shallows.
That trip on Tuesday caused me to share my own assumptions about why the bite slows during midday compared to daylight hours and why the bass and bluegill that were aggressive in the early morning hours change their feeding patterns in midday through mid-afternoon.
I am going to limit my reasoning solely to the bass and bluegill species that I fish for in my home waters, Smith Lake and Walker County Lake.
If you have followed my blog over the years, you know that my favorite time to fish is at daylight. Simply put, that is when the fish are the most active! Why is this? Because fish like bass, bluegill, or even trout often hunt best in low light, when their prey is less able to see them. Insects and small baitfish are more active or more vulnerable at dawn and dusk, making them an easy meal for a hungry bass or trout, and they are less visible to birds and surface predators during these times. Daylight and evening hours often bring cooler water temperatures, ideal for many species, especially in warm months. Cloudy or overcast skies subdue sunlight, mimicking dawn/dusk conditions, and will extend active feeding times. Cloud cover can also signal an incoming weather system, which often triggers a feeding frenzy before pressure drops. That is why I pay close attention to the barometric reading before and during the times I am on the water.
If you fish long enough, as I have, you will notice the active feeding time during daylight hours lasts two to three hours, depending on cloud cover. The bite slows from 9 AM until midday because the high sun makes the fish more visible to predators, so they often retreat to cover or deeper water. The insects and baitfish may also retreat or hide during the heat of the day, reducing available food.
Take heart, there are ways you can still land fish during the slow midday bite. First, I slow everything down, starting with my casting and boat movement, and develop more patience. The fish haven't developed lock-jaw at this time of day, but you must entice them to take your offering. Remember that the fish will not attack your popper as aggressively as daylight hours, so letting the fly sit motionlessly for at least 30 seconds or more will sometimes get a take if the fly is in a shaded area or near cover. I have noticed many times during a slow bite period that the fish will slap, swirl, and sip the bug. The slap, swirl, and sip routine is the time I change to a smaller popper in the form of a size 12 caddis, bogglebullet size 10, or the Orvis bream bug size 12. With these poppers, you are trying to create a quite stealthy presentation. I use my 9ft. 3 and 4-weight rods rigged with a 6X tippet instead of the normal 5X or 4X tippet used with my 5wt. or 6wt. fly rods with these flies. Most of the time, one of these three poppers will produce a take. Remember the amount of water you are covering with no fish in it. So when you encounter a fish to hit your offering during this period, make a great cast, present the fly as life-like as possible, and have the patience to let the fly sit until the water rings have disappeared. The slow bite can be rewarding and discouraging, but remember to stay positive and think every cast will produce a take!! LET'S GO FISHING!!!
