Spring is here, and with it comes the runoff season – a time when snowmelt causes rivers to swell and water flows to surge. While the high water might seem intimidating, it’s actually a great time to hit the rivers for some fly fishing action. With the right approach and a few handy tips, you can make the most of this dynamic season. Let’s dive into how runoff impacts fish activity and bug life, and which fly patterns are your best bet for a successful day on the water.
Understanding Runoff Season
Runoff season occurs when the snow from higher elevations melts and flows into rivers, raising water levels and increasing current speed. This can significantly impact both fish and insect activity. The higher, faster, and often murkier water can disperse fish and make it harder to spot them. However, fish still need to eat, and understanding their behavior during this time can greatly improve your chances of success.
Fish Activity During Runoff
Seek Out Calm Water:
Fish tend to avoid the strong currents and seek out calmer areas where they can conserve energy. Look for slower-moving water along the banks, behind boulders, or in deep pools and eddies. These are the spots where fish are likely to hold and feed.
Focus on Depth:
Higher water levels mean that fish might be deeper than usual. Adjust your strategy by using weighted flies or adding split shot to get your flies down to where the fish are holding.
Take Advantage of Rising Water:
As the water rises, it often floods new areas, pushing fish into places they wouldn’t normally be. These newly submerged areas can be hot spots for feeding fish, especially near the banks.
Bug Life During Runoff
Hatch Timing:
Runoff can affect the timing and duration of hatches. While some hatches may be delayed, others can be more prolific as warmer temperatures and increased flows stimulate insect activity. Pay close attention to the types of insects present and match your fly patterns accordingly.
Use Larger and Brighter Flies:
Murky water can make it harder for fish to see your fly. Using larger, more visible patterns can help. Bright colors and patterns with added flash can also attract attention in these conditions.
Recommended Fly Patterns for Runoff Season
- San Juan Worm:
This pattern mimics worms that get washed into the river during high flows. Its bright color and simple design make it easy for fish to spot in murky water. It’s a reliable choice for runoff season.
- Stonefly Nymphs
Stoneflies thrive in fast, turbulent waters. A stonefly nymph pattern is an excellent choice, especially one with a bit of weight to get it down to the fish. Look for patterns with rubber legs and a bit of flash to catch the fish’s eye.
- Streamers:
Larger, flashy streamers like the Woolly Bugger or Zonker can be highly effective during runoff. They mimic small fish and other prey that get dislodged and swept into the current. The added movement and visibility of streamers can trigger aggressive strikes.
- Caddis Larvae and Pupae:
Caddisflies are abundant in many rivers, and their larvae and pupae are a staple food for trout. Patterns like the Green Rock Worm or the Beadhead Caddis Pupa can be particularly effective.
Tips for Success
Use Heavier Tackle:
The stronger currents and higher water levels mean you’ll need heavier tackle to control your fly and bring in fish. Consider using a 5 or 6 weight rod and a sturdy leader.
Be Safe:
High water can be dangerous. Always be cautious and prioritize safety. Wear a wading belt, use a wading staff, and avoid areas with extremely fast currents.
Adjust Your Presentation:
Fish may not be as willing to move far to take a fly during runoff. Make sure your presentations are precise, and don’t be afraid to make multiple casts to the same spot.
There you have it, anglers – a few tips to help you navigate the challenges of runoff season and come out on top. With a bit of preparation and the right fly patterns, you can enjoy some fantastic fly fishing even when the rivers are running high. So gear up, stay safe, and tight lines!
