Welcome to the board. The spring bass bite is just around the corner though the recent weather supposedly has helped he bite for just about everything around the small tributary inflows.. Fishing Berryessa out of a kayak should be a piece of cake.

The majority of my fishing up there is in a float tube and tossing split shot and small 4" rubber worms or reapers in various colors.  I used some crank baits last year with decent success, including a nice salmon. I have used a fly rod in the past with some success.

This is usually where I launch my float tube, at the back of the cove.  I just paddle to the point and and fish it for a few minutes before moving out to the island

I fish around the island in a counter clockwise direction.  The majority of the fish come off of the lake side of the island but the N and NW side seems to produce a disproportionately number of smallmaouth for some reason.  The near side of the island usually doesnt produce many fish for me.  I spend an easy hour or so at that island.

After fishing the island I head due North to the next point (in high water years it is an island).  Starting last year when I landed a nice salmon on a plug, I pull a lure from the island to the point.  That way I'm fishing and not just paddling right  :) 

The vast majority of my fish come off of the lake side of the point.  North of the point is a large cove that usually produces fish.

I follow the shoreline up to this location and hit the cove pretty hard.  I've landed a LOT of fish out of that cove.  I usually don't venture past that point.  I follow the shoreline on the way back and tend to drag the bottom real slow but do target the points when I get to them.

Tight to the bank while slowly dragging the bottom here and here tend to produce a lot of smallmouth.

Bites are anything from a single or couple of taps, mushy feeling, continuous slack line (fish swimming with line towards you), mushy feeling or your line is just moving diagonally.

Starting that loop at first light usually puts me back in the cove I launched from by 2 or so.  This certainly isn't the only spot to fish but for a float tube it has worked well for me.

If I just want to get out on the lake and have limited time I usually head to the old boat launch just past the dam and follow the shoreline back towards Markley cove.  Never a lot of fish but usually something.  Just note that the dam side of the lake warms up later in the Spring than the far side of the lake so the bass bite lags a bit.
