I noticed a down slide, but I don't think its exclusively due to gobies. The lake is changing and so is the forage base, so things are in flux. I'm catching good numbers and even better size class this summer. I don't know if there will 100 fish days like there were in the early 90s, but it isn't all that bad. Many of the fish I've caught have gobies (and big gobies at that) in their craw. That should be a big clue as to how to fish for them. Big tubes have worked consistently for me lately, though other baits catch them as well.
