Southern Catskill Fly Hatch Chart

Fly charts are very useful in determining the correct fly to use when fly fishing for Trout based on the fly hatch that is going on at any given time of year. Conditions such as water and air temperature can effect the overall fly hatch so pay attention to the elements when determining which fly pattern to use.

This fly chart includes most of the important Mayfly and Caddis hatches for the Southern Catskill and Northeastern US. May fly hatches are represented by yellow cells, the Caddis fly hatches by red cells. NOTICE that the fly species name and the common name are clickable links that will take you to a page of information dedicated to that specific fly chart.
