like this are fish magnets. Many species of fish will
line up just downstream from places like this and wait
for something to be washed into the river. Very often
the incoming water will be warmer than the river.
Some fish will be present right where the water enters
the river and other will be several feet down stream.
Live bait pitched
into the waterfall will catch fish on almost every cast.
Boats should be positioned downstream and out as far
as possible. Lures should be pitched above the waterfall
and allowed to drift right past the water flowing into
the river. Lures that don't snag can be pitched up into
the waterfall. Be ready for fish to jump into the waterfall
after your lure.
Remember that if you get to close to the waterfall,
the fish will spook. Even if they don't leave, they
will not usually hit anything while they are spooked.
