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 Crummock Water: what the data says

617-acre lake near Cumbria. The lake tops out around 144 ft. The depth chart comes from British Library bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.

The outline encloses 615 acres, worked by 6.1 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 12% of the surface — that's where the groceries are. End to end it runs roughly 2.5 mi, about 0.6 mi across. Cumbria claims this one. Its nearest charted neighbour, Buttermere, is 2 mi to the southeast.
