Shore fishing works good for me all year round. Personally i don't think it affects the bass. Not being use to boat fishing i fish from shore all year long, i have cought bass in under foot deep of water. As long as there are weeds to give off oxygen the bass are fine, as for pike, musky etc....im not to sure. Up at Baptist Lake near Bancroft i have seen Large Musky just cruising the shoreline in the heat of summer. It depends on the species and the structure of tha area.
