We went to Matagorda a few weeks ago but it was the day after they had 14 inches of rain just north of there. Fishing was tough, water wasn't salty at all and the bay looked like yoo-hoo. They had a tournament that weekend and limits were fairly scare.
I heard last week though the trout bite was on using live croaker. The surf is hot if the waves are wadable. Forecast looks good. I'll either be there or down Corpus way. Haven't decided yet.
