I was on the G-Pool last weekend as well for the first time.
Like others have mentioned earlier in this thread. Possibly one of the most pressured lakes I personally have ever fished my in my entire life. Every "fishy" spot that I pulled up to had at least 1, sometime 2 or 3 other boats fishing there. Keep in mind there was a Jr bass tournament last weekend, but there was only 10 boats entered. I must have seen easily 100 other fisherman on the lake that day.
Fishing was great for the first 2 hours of the day, then it died down when it got really hot out.
