April 1st is the start of the Salmon season, and judging by the amount of open water, it isn't looking too good. Salmon show first in Alton, but they don't show until the ice is out about to the Bandstand. As of today (ignore the stuffed owl) the ice is barely past the Downings Landing dock:
WMUR's weather page says temps will stay cold for the rest of this week, so not much melting in the offing. It may be a late-starting season this year, asnd it will be even later in Wolfeboro.
The Salmon come in at Wolfeboro about two weeks after they show at Alton. Rainbows can be had in Wolfeboro before the salmon show, though. In past years I have gone to the town docks when the ice was out about as far as it is now, and seen trout hitting small bugs hatching out on the surface right next to the edge of the ice.
Here's a crop from the web cam as of a few minutes ago:
I wouldn't be surprised if there were trout lurking along the edge of that ice line. Come April 1, we may find out if I am right.
