Glad to hear it's open!

The following list of lakes, reservoirs and ponds identifies sites that are frequently stocked with rainbow trout, and some with brook trout, brown trout or cutthroat trout. Water bodies appearing below are open all year with a trout limit of five. The harvest of game fish species other than trout from stocked trout waters is not permitted. Stocked waters where the harvest of other species is allowed or where bait restrictions apply are listed under "Lakes and Streams Listings" for each Watershed Unit.
Several additional sites stocked with rainbow, brook, brown, cutthroat trout or arctic grayling are not identified in this section, but appear with special regulations under "Lake and Stream Listing" for each Watershed Unit.

To me it sounds like if it's a trout, you're good to go. But I do seem to remember one year where the regs specified that only the TYPE OF TROUT STOCKED AT THE SPECIFIC SITE COULD BE HARVESTED. I could easily be wrong. The wording in the current regs is slightly ambiguous.
