Baum Lake

Baum Lake venue image

Small, cold, spring-fed lake over in the Hat Creek country — clear and weed-rich, with the kind of stable temperatures that keep it fishing all year while everything else freezes or boils.

A patient day, if you fancy it
Water temperature is the limiting factor today, not the wave. Fish dawn or dusk if you go at all, and handle everything with extra care.

How to fish it · for Rainbow
When
No strong hatch signals at the moment — general searching tactics should work best. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

Conditions are away from Baum Lake's sweet spot — it usually fishes best in ripple wind with cloud skies.

About this water

Small, cold, spring-fed lake over in the Hat Creek country — clear and weed-rich, with the kind of stable temperatures that keep it fishing all year while everything else freezes or boils. It holds wild rainbows and browns, and because the water's so clear it's technical: fine tippet on the flats, static chironomids, and dries you sight-fish to cruising fish on the calm days. A tube or pram lake, quiet and rewarding if you slow down enough to read it.
