There are 2 off limit areas. The main spillway which is used to move water from the big lake,thru the lower lake to the santa clarita river. The area would be difficult for a boater to fish as it is a large area in plain view of everyone. It is quite shallow at that end of the lake but I have been told that at the foot of the spillway there is a large, deep bowl type depression lined with huge rocks which along with the verticle cement walls makes prime big fish structure. This area is inacessable to bank fisherman and boaters. The other restricted area is the narrower overflow spillway seperated by a point adjacent to the main spillway. This area is partially obstructed from view. Likewise it has deep water (25'), vertical walls merging with rock rip rap banks. It is just beyond reach of a good long cast with a swimbait. This is the area referred to.
