I have always been interested in fishing ELDERBERRY FOREBAY (see any detailed map). This is the far northern area of Castaic Lake behind the north side dam of the "ski arm" seperate from the main lake. I believe this is a reserve lake for the DWP. This is not the LOWER LAKE. It seems hard to gain access. I did some scouting one day. It looks like you will need to be dropped off with a cel phone to get picked up later. Sounds pretty adventurous. After being dropped off you will need to do some hiking. The amount of hiking depends on where you get dropped off at. If anyone has or goes there, please let me know the results. CURIOUSITY KILLED THE CAT (or fish in this case).
