Aj….
Foster ice depends on the weather and snow. Christmas usually has Foster locked up fairly tight.
The lake has a healthy trout population that’s maintained for cast and keep, just like the SE trout streams. They stock it pretty good around the Christmas break period.
Don’t need anything fancy. Some people use minnows on a hook or small jig. Some will sink Power Bait dough on a hook with a split-shot. My personal preference is for a 1/12 [maybe its a 1/10] ounce Kastmaster jigging spoon in gold with a piece of orange tape on one side….this combo drives trout nuts in that lake. 1/10 ounce Little Cleos in gold with an orange stripe work well too. I usually up-size the hooks by one size and add a spike or two or a waxie to the equation for the scent.
Any rod spooled with 4 to 6 pound line, mono or fluoro will be best since you’ll be fishing in 10 to 15 feet of water or less most of the time. The water is very clear and braids can turn the fish. Low light periods can be outstanding as far as catching goes, but with snow on the ice and frequent clouds even a mid-day bite can be had.
If you’re here anyway, give the lake a try. Must have a trout stamp to possess the trout, which are under special regulations for year-round catching/keeping: 3 fish limit, only one over 16″.
