Hi,
Unlikely that this was a white fish caught in July in such shallow water, as they are down deeper (where the salmon are) by then. You might have caught a "roach" (Fallfish). Check out FRESHWATER FISH OF NH (on sale at Fish & Game hqs) or my book, ANGLING IN THE SMILE OF THE GREAT SPIRIT -- SIX CENTURIES OF WISDOM FROM THE MASTER ANGLERS OF LAKE WINNIPESAUKEE, now on sale at
www.deepwaterspress.com. There are pictures of White fish (locally called "shad") and Roach in both books. I used to catch one or two whitefish (one of the finest eating fish in the Lake) every year while trolling for salmon and lakers, but it has been 8 years since I have caught one. The "old timers" (funny that I should call them old timers at my age!! Ha!) used to catch them through the ice by chumming a hole for several days and then fishing thru the ice with small bits of smelt or meal worms.
Good angling!
