Hatch Charts.

I've noticed a fair amount of traffic comes this way via searches for hatch charts for both the Grand and Upper Credit Rivers. Lets talk about charts for a second.

First off, for those new to the sport, charts can only be so accurate. Bugs don't use a calendar. Probably the most accurate method would be phenology. Years like this, where spring weather conditions were accelerated, the bugs were too. Some years they get pushed back. What they are good for is giving you a general idea what should or could be on the water, and what should be coming up. The internet is also a good resource. Many shops have river reports online and will clue you in to the currently producing hatches. Blogs such as this one can also tell you what others are finding successful.............though, buyer beware..........anyone can write a blog. Some are excellent anglers. Others are not, like the hack who writes this blog. The well known fly fishing author John Gierach once said something along the lines of 'there are good anglers, and there are good writers. Seldom are they one in the same.'

Of course, the easiest way to find out what the fish and the bugs are doing is to get out there and look.
