About fly fishing

Fly fishing trades lure weight for line weight: the line carries a near-weightless fly to fish feeding on insects and baitfish. Learning a clean cast and reading current matters far more than the fly box.

Season: Year-round on many tailwaters; peak insect hatches in spring and fall. Seasons, licences and limits are set by each state or province; check the current regulations before you go.

Learn these first

  • An overhead cast and a roll cast
  • Reading riffles, runs, pools and seams
  • Choosing dry, nymph or streamer by what fish are eating
  • Tying tippet to fly with an improved clinch knot

Kit that matters

  • A 9-foot 5-weight rod and matched reel and line for general trout water
  • Leaders and tippet in a few sizes
  • A small selection of dries, nymphs and streamers
  • Waders or wet-wading shoes, polarized glasses and a net

The fly fishing guide

Fishing is reading water: where fish hold, what they eat and how conditions change that. A simple setup and lots of time on the water teach the most.

Buy your license, check species rules and handle fish carefully if you release them.

How to progress

  1. Step 1

    Getting started

    Spinning setup, panfish and stocked trout, basic knots.

  2. Step 2

    Building range

    Species-specific tactics, fly fishing basics, reading structure.

  3. Step 3

    Going further

    Remote waters, fly tying, boat and kayak fishing.

Before every trip

  • Buy the correct license and check special regulations
  • Check water levels and temperatures
  • Carry pliers for safe releases
  • Plan around dawn and dusk feeding windows

Honest hazard notes

  • Wading in fast or deep current
  • Slick rocks; a wading staff helps
  • Cold water and sudden dam releases on tailwaters

Fly Fishing seasons & weather handling

Spring and fall, when water temperatures sit in the feeding range and fish hold at reachable depths.

Spring

Prime
Days
50–70°F
Nights
32–48°F

Warming water pulls fish shallow — hatches begin and pre-spawn feeding peaks.

  • High, off-color runoff
  • Cold-water immersion if you wade a strong flow
  • Spawning closures on some water

Fall

Prime
Days
50–70°F
Nights
30–45°F

Aggressive pre-winter feeding and the least pressure of the year.

  • Cold nights and short daylight
  • Turnover scattering lake fish
  • Frost-slick ramps and rocks

Summer

Good
Days
75–92°F
Nights
55–70°F

Early and late windows produce; midday fish go deep or shaded.

  • Warm water stressing released trout
  • Afternoon storms on open lakes
  • Sun exposure and dehydration

Winter

Marginal
Days
20–42°F
Nights
5–28°F

Slow presentations in deep, stable water — or hard water where it's safe and legal.

  • Ice thickness — never trust unmeasured ice
  • Frozen guides and numb hands
  • Hypothermia after any immersion

Weather playbook

  • Water temperature drives everything — carry a thermometer and fish the band your target species feeds in.
  • Overcast, falling pressure, and a light chop usually beat bright, flat, high-pressure days.
  • After heavy rain, look for clearing edges and inflows rather than chasing muddy main water.

Numbers that decide the day

Trout window
50–65°F water; back off above 68°F to avoid killing released fish
Bass window
60–80°F water, shallowest right after warm rain
Off the water when
Lightning within 10 miles or whitecaps on your crossing

Planning ranges are typical temperate-latitude values — always verify the forecast, flow, avalanche, and fire advisories for your specific area and elevation before you commit.

Fly Fishing FAQ

What rod should a beginner start with?

A 9-foot 5-weight is the common all-round trout choice and handles most small to mid-size rivers.

Dry flies or nymphs?

Fish feed below the surface most of the time, so nymphs often catch more; switch to dries when you see fish rising.
