What to Expect in April
Hatches divided by half-month.
Super Major Minor Slight None
Tan beadhead flies in size 14 and red midge pupa patterns are good choices. Large flies, such as a size 4 Woolly Bugger or Matts Fur , can pick up trout when retrieved on a sinking line. Vary your retrieve. Sometimes a very fast retrieve is needed to induce a strike.
Later in April you may see some of those black, size 10 mega-midges that hatch in desert stillwaters. Trout love 'em when they're out, and can be very selective. A size 10 midge pupa pattern with a black body and silver or white ribbing will do the job. Let it sit or give it a very slow retrieve.
Beware of the weather in April. It can be brutally cold and windy. If you get blown or snowed off Mann, trek down the road a few miles to the Alford hot springs and soak your cold body. You'll need to leave your clothes and modesty on the bench.
