Rain always makes me hungry...I'm not exactly sure what species I am though:think:
In my limited experiance, Rain turns the bite on for lots of species.
First OFF- When it rains it knocks food out of the sky (bugs) and OFF of trees and what not into the water. I've have some amazing days at Harriet in the summer after a good rain.
Second- When it rains the rivers rise, when the rivers rise, migratory fish can travel upstream with less obstructions. Therefore its logical to summize that because they are moving more they need more energy.
Ive noticed that when a low pressure sytem moves in after a few days of high pressure thats when it gets hot! Low pressure means changing weather which usually includes rain.
Probably the most improtant reason the fishing is better in the rain is, Only the die hards stand in 36 degree down pour day after day just for the chance to get broken OFF. Those are the people I want to fish with, and thats when I remember catching the bigguns. I LOVE THE RAIN.
Thanks Oregon,
