Gochoa, Check out the California Department of Fish and Game website for trout planting during the week that you will be at the Whitney Portal Campground. For example, this week there are plants at all the nearby creeks, including Lone Pine Creek. Not infrequently a Fish and Game tanker is seen stopped next to the bridge between campsites 15 and 16 as the warden releases scores of large trout into the creek. Right after a planting do not plan on being the only fisherman at the lucky spot, however. If you are at campsite 15 or 16 that evening, you will hear the bears fishing down at the creek too. Good luck out there. Jim
