Lake Casitas Bass Fishing Guide Report 04/10/2016 – Guiding every single day at Lake Casitas the bait situation has been very much hit and miss. You might get it one time a week. Friday I fished from sun up till 5 PM and didn't see anything at all. Saturday morning when I was sending the boats off for our Western outdoor news tournament the entire marina was choked with live threadfin shad. These are big baits. Just an amazing amount of activity with birds and the shad moving to shallow water. As of this morning I'm heading to work and pretty sure that this is the beginning of the shad season at Lake Casitas.
