No question, there seems to be no rhyme or reason to the normal schedule of hatches in NE US on many rivers. We fish the Natchaug in Eastern CT and a look at the the following: USGS Real-Time Water Data for USGS 01120790 NATCHAUG RIVER AT MARCY RD. NEAR CHAPLIN, CT
will give you and idea why. From barely a flow a few days ago to high water conditions; from hot to cool; and this pattern has repeated itself throughout the Spring. The hatches have been inconsistent and sparse and the fish unable to establish any rhythm as far as taking insects on top.
Much of our success and that of our guests have been on emergers just under the surface when the trout let even naturals pass by on the surface undisturbed. Soft hackles and CDC emergers have been particularly effective in the surface film or just under. An abnormal year hatch-wise for sure!
