a newbie myself, but here's my two cents worth.
i usually put in at leavenworth and go up river.
like yourself, i see the river everyday at work.
i stopped to look at it yesterday on the way home from work and what i saw was most of the ice settled into the "idle water" areas i usually used going up river.
i haven't been to the leavenworth park yet, but would assume the egress to the water to be plugged by that idle water ice.
looked like there was room in between the pancakes in the channel.
i've heard of duck and goose hunters floating with ice on.
lookes fairly clear this morning, going to the park tonight after work just to see what it looks like there.
be safe!!!
