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 Avich: what the data says

859-acre lake near Argyll and Bute. The lake tops out around 188 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from Murray & Pullar's Scottish loch survey of 1903, digitized from the bathymetric atlas published in 1910. The rest of this page walks each species through its year, using the map's own scoring.

Traced from the shoreline, Loch Avich runs 858 acres with 8.2 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 20% of the surface — that's where the groceries are. Tip to tip the water measures near 3.2 mi with a 0.7-mi widest point. The water lies in Argyll and Bute. For a second option, Loch na Sreinge lies 2 mi north.

Brown Trout fishing at Loch Avich

Spring brown trout on Loch Avich hold shallow, usually 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. Put Main-lake point first on the milk run — a point near 2 ft that grades prime for spring. The feeding windows run 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	Main-lake point (2 ft)	Stickbait off planer boards (shallow), Small spoon along mud lines
Summer	25 to 60 ft	night & dawn	open water	Spoon at the thermocline, Deep stickbait (night)
Fall	5 to 30 ft	dusk & dawn	Main-lake point (2 ft)	Jerkbait over gravel, Casting spoon
Winter	5 to 35 ft	dawn	open water	Jigging spoon, Small stickbait (slow)

European Perch fishing at Loch Avich

In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. Spring european perch concentrate at Back-bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and you'll meet the bite. 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	Back-bay flat (2 ft)	Small jig + curly tail, Inline spinner #1-2
Summer	8 to 28 ft	dawn	Feeding flat (10 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	Feeding flat (29 ft)	Tungsten jig + maggots, Small balance jig

Northern Pike fishing at Loch Avich

In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Back-bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Time it for early morning and the evening. 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	Back-bay flat (2 ft)	#5 inline spinner, Spoon (red/white)
Summer	8 to 20 ft	dawn & dusk	Feeding flat (10 ft)	Bucktail, Weedless spoon over cabbage
Fall	6 to 18 ft	midday & dawn	Feeding flat (10 ft)	Big rubber (Bull Dawg style), Husky-style jerkbait
Winter	5 to 15 ft	midday	Feeding flat (10 ft)	Tip-ups, Large jigging spoon

Arctic Char fishing at Loch Avich

Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Start at Feeding flat. It's a feeding flat holding about 10 ft of water and rates good come spring. Prime time lands in 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	Feeding flat (10 ft)	Small casting spoon (silver/orange), Jerkbait (small)
Summer	20 to 60 ft	dawn	open water	Jigging spoon vertical, Tube jig (smelt)
Fall	8 to 30 ft	midday & dusk	open water	Casting spoon (orange/gold), Beadhead streamer
Winter	10 to 40 ft	midday & dawn	open water	Jigging spoon (glow/silver), Tungsten jig + plastic
