An eight-acre fly-only reservoir near Old Polmont, Falkirk — bank and boat fishing, casting platforms, stocked rainbow, blue, and brown trout. The smaller scale makes it a practical central-Scotland venue when larger lochs are too exposed or too far.
A patient day, if you fancy it

How to fish it · for brown trout
When
The hawthorn fly is on. Drift conditions look good — cover the wind lanes.
Where
Set up a broadside drift and cover the water systematically. Work Dry Fly on the bob and Emerger on the point. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Dry Fly on the bob and Emerger on the point. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
