Floodlights at the dock

Hey all! I used to live in west seattle 7 years ago and I had fond memories of going down to the water taxi dock at night, fishermen down there would point floodlights into the water and use neon fishing lines for some night fishing and it was really pretty to watch. Is this still something that happens? I was thinking of coming back to visit and check it out. Also do they just do it during the warm months? Thanks in advance!
