Hatch outlook

Sedge season & the MurroughActive window

Typical here: Jun 1 – Sep 30 · the Murrough and Green Peter are lough patterns from July, peaking the last weeks of August; evening sedge fishing runs to the season close

pupawarm summer evenings as the light fades
adultlate evening into dark, on calm water — the great red sedge is large enough to provoke explosive surface takes from big trout — fished dry off the shorelines and on the drift

Big-fish-on-top fishing in the last two hours of light — the sedge weeks of late August produce some of the best days of the lough year.

The evening sedge pulls big trout to the shorelines in low light — exactly when small surface plugs and slow-twitched 4–5cm minnowbaits shine along the rocky shores and weed edges; or run a bubble float with a dry Murrough behind it, twitched on the pause.

The event happens over lough shorelines, rocky shallows and weed edges on warm, calm summer evenings

Daddy-Long-Legs (crane fly)Active window

Typical here: Jul 1 – Oct 15 · dapped daddies documented from early July on Corrib; the famous window is mid-August through September, with grasshopper dapping in the same weeks

adultdaytime, on a drift with a wave — best on the breezy days that blow craneflies off the banks — the documented method is dapping: a natural or artificial daddy on a long rod and floss line, skipping across the surface ahead of the drifting boat; a dry daddy on the drift is the modern equivalent

The autumn wake-up: big trout that ignored everything through June and July suddenly become aggressive — often the largest browns of the season on a dry fly.

Fish the windward drifts where the terrestrials land — surface plugs twitched on a wave, or a bubble float trailing a daddy skipped on the surface (dapping with spin gear, effectively). The late-season big-fish window before the September close.

The event happens over windward shorelines, island shallows and drift lines on breezy August–September days

Fishing Loch Duntelchaig or Loch nan Geadas: what the data says

1,368-acre lake near Highland. The lake tops out around 205 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.

On the chart, Loch Duntelchaig or Loch nan Geadas draws 1,365 acres inside 9.2 miles of shoreline. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 7% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 3.2 mi with a 1.2-mi widest point.

Brown Trout fishing at Loch Duntelchaig or Loch nan Geadas

Spring brown trout on Loch Duntelchaig or Loch nan Geadas hold shallow, usually 3 to 25 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 5 to 35 ft. The chart's best answer is Main-lake point — point, 51 ft, prime for summer. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 25 ft	dawn & dusk	open water	Stickbait off planer boards (shallow), Small spoon along mud lines
Summer	25 to 60 ft	night & dawn	Main-lake point (51 ft)	Spoon at the thermocline, Deep stickbait (night)
Fall	5 to 30 ft	dusk & dawn	open water	Jerkbait over gravel, Casting spoon
Winter	5 to 35 ft	dawn	open water	Jigging spoon, Small stickbait (slow)

European Perch fishing at Loch Duntelchaig or Loch nan Geadas

In spring, european perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 12 to 33 ft. Shallow bay flat is the standout, a feeding flat at roughly 6 ft, rated prime for spring european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	Shallow bay flat (6 ft)	Small jig + curly tail, Inline spinner #1-2
Summer	8 to 28 ft	dawn	Shallow bay flat (6 ft)	Drop-shot micro plastics, Small crankbait (perch pattern)
Fall	10 to 33 ft	midday	open water	Jigging spoon (small), Drop-shot on deep flats
Winter	12 to 33 ft	midday & dawn	open water	Tungsten jig + maggots, Small balance jig

Northern Pike fishing at Loch Duntelchaig or Loch nan Geadas

In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated feeding flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	Shallow bay flat (6 ft)	#5 inline spinner, Spoon (red/white)
Summer	8 to 20 ft	dawn & dusk	Shallow bay flat (6 ft)	Bucktail, Weedless spoon over cabbage
Fall	6 to 18 ft	midday & dawn	Shallow bay flat (6 ft)	Big rubber (Bull Dawg style), Husky-style jerkbait
Winter	5 to 15 ft	midday	Shallow bay flat (6 ft)	Tip-ups, Large jigging spoon

Arctic Char fishing at Loch Duntelchaig or Loch nan Geadas

Come spring, look for arctic char tight to the bank in 4 to 15 ft. They move out to 20 to 60 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores good in spring. Best bite is early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	4 to 15 ft	midday & dawn	Shallow bay flat (6 ft)	Small casting spoon (silver/orange), Jerkbait (small)
Summer	20 to 60 ft	dawn	open water	Jigging spoon vertical, Tube jig (smelt)
