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 Glass: what the data says

1,186-acre lake near Highland. The lake tops out around 365 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 1902, digitized from the bathymetric atlas published in 1910. The season-by-season read for each species follows, from the map's own numbers.

The outline encloses 1,183 acres, worked by 8.8 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. Roughly 6% of the water is 15 ft or less, the band where the food chain lives. Figure 3.8 mi of water from one end to the other, 1.1 mi at the beam. Highland claims this one. Loch Morie or Loch Glass sits 3 mi northeast — the closest neighbouring chart.

Brown Trout fishing at Loch Glass

Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 5 to 35 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.

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	open water	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 Glass

Early season european perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 12 to 33 ft. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	open water	Small jig + curly tail, Inline spinner #1-2
Summer	8 to 28 ft	dawn	open water	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 Glass

Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

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

Arctic Char fishing at Loch Glass

The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	4 to 15 ft	midday & dawn	open water	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
