It is legal to use salmon eggs on both Henrys Lake and Island Park Reservoir.
It is illegal to use minnows of any kind in either Henrys or IP, or to have them in your possession above Mesa Falls on the Henrys Fork.
Minnows are not a significant source of food on Henrys Lake. There are a lot of dace and shiners in the lake, but they are only about 3% of the food for the trout there. The major source of food are scuds and then other nymphs. Brook trout will utilize minnows more so than other species, but not that much - too much other food without using effort.
The chubs are alive and well at Henrys Lake. There are times that we see them, but they now have been located throughout the whole lake. When the water starts warming - late July and early August they are caught during the moring around Staley Springs. Also in the fall they are caught around the Cliffs. They are not a serious problem at Henrys right now, but could be in the future.
The trout population on Henrys Lake is down, but I think that it is drought related rather than chub related. In the 1990's about 75% of the trout in Henrys came from natural spawn - now it is estimated at under 10% because of lack of water in the tribs during the late summer and fall.
Hope this helps.
