In the heart of Yellowstone Park is a giant blue gem called Yellowstone Lake, not a very imaginative name, but appropriate. Yellowstone Lake is the largest lake at high elevation (i.e., more than 7,000 ft.) in North America with a surface area of about 84,000 acres of 132 square miles; it is a natural lake, situated at 7,733 ft above sea level. To the east of Yellowstone Lake are the snow-capped peaks of the Absaroka Mountain Range and to the north the Beartooth Mountains grace the skyline; its kind of like Lake Tahoe except with geysers on its beaches. The Yellowstone Lake is a beautiful, clear and deep, body of water. In the center of our countryÍs first National Park.

Yellowstone Lake was probably first seen by an American in the winter of 1807-1808 by John Colter on his famous winter trip of discovery. In 1826, fur trappers Daniel Potts, Bill Sublette, and Jedidiah Smith called Yellowstone Lake "Sublette Lake," By the 1860s, Yellowstone Lake was well-known among trappers, army personnel, and explorers as Yellowstone Lake.

Yellowstone LakeÍs high elevation insures that it remains cold year-round, with an average temperature of 41ÁF. It is roughly 20 miles long and 14 miles wide with 141 miles of shoreline. It freezes in late December or early January and thaws in late May or early June. Yellowstone Lake has an estimated capacity of 12,095,264 acre-feet of water; so itÍs annual 1,100,000 acre-feet of outflow takes about eight to ten years to refill this 132 square miles landmark.

Researches with a small submersible robot submarine have discovered that if one could empty Yellowstone Lake, the lake bottom would reveal it is similar to what is found on land in Yellowstone; geysers, hot springs, and deep canyons. Underwater geysers, hot springs, and fumaroles all were found in the lake. The hottest spot in the Yellowstone Lake was found at Mary Bay where temperature was recorded at 252 degrees. The robot sub found a canyon, which was 390 ft. deep; previously the deepest spot in the lake was thought to be 320 ft. deep. Yellowstone LakeÍs thermal features appear to be similar the famous hydrothermal vents on the Pacific Ocean that support strange animal and plant communities, including bacterial mats, sponges, and earthworms that exist in conditions previously thought impossible.

Much of Yellowstone Lake is in the Yellowstone Caldera. The Yellowstone Caldera, sometimes known as the Yellowstone super-volcano, is a volcanically active region that measures 35 miles by 45 miles. Yellowstone is believed to lie on top of one of earthÍs few dozen hotspots where molten mantle rock rises towards the surface. In recent years the ground under Yellowstone Lake has risen significantly, indicating increased geological activity. Beneath a section of Yellowstone Lake, where there are faults, hot springs and small craters. A new bulge in the earth has been discovered that measures roughly 2000 feet long and 100 feet high; Yellowstone is a dynamic place! In the West Thumb geothermal area, on the south side of the lake, an area easily accessible to visitors. Here you can see geysers, fumaroles and hot springs alongside and even in the lake to give you an idea of what lies beneath.

Yellowstone Lake has 124 tributaries; at least 60 being cutthroat trout spawning streams. Recent findings show that 80 or more grizzly bears fish these streams around Yellowstone Lake during cutthroat trout spawn; so if you plan to fish during the spawn, be extra vigilant and know how to use your pepper spray.

Yellowstone Lake is home to the worldÍs largest population of inland cutthroat trout and fishermen from all over the world come here to try their luck at coaxing them up out of their watery home for a visit. Yellowstone Cutthroat are the only endemic trout species in Yellowstone Lake. In this extremely productive lake cutthroat trout average 16 inches. Both wet and dry flies work on Yellowstone Lake and which to choose will depend on the hatches. Trolling and casting wet flies from a stationary boat both are effective. If conditions avail themselves you can cast a dry fly to a cruising trout; much like stalking a bonefish on the flats. Spin fishing also works very well on Yellowstone Lake; ultra light rigs with 6 - 8 pound line works best. The lake opens for fishing on June 15th.

The north shore is accessible by road but the remainder of the lake must be accessed by boat or on foot. The road form West Thumb to Fishing Bridge goes by the lake in few spots and isnÍt very far away for most of its length. Boats with motors are not permitted on the south arms of the lake. Most cutthroat feed near the lakeshore due to the depth of the lake. In early summer the fish follow the shoreline to locate their spawning streams. Some of the best fishing is near the mouths of these spawning streams. Wet-fly fishing is most productive. The cutthroats are far from selective and almost any pattern will work

.

Despite the huge size of Yellowstone Lake good fly-fishing from the shoreline can be very productive. The reason the cutthroat trout are generally found along the shoreline is because the bulk of all aquatic insect activity occurs in the warmer, shallow, waters near the shore. A boat or float tube does come in handy to chase down the trout that are found outside of casting range. Although hiking trails follow the lakeshore a boat may also enable you to easily reach areas that are found away from the roads,

A 1994 discovery of Lake Trout in Yellowstone Lake has alarmed most anglers and biologists; when discovered the Lake Trout were first thought to be recently introduced, but further investigation shows Lake Trout may have been in Yellowstone Lake much longer; possibly for up to forty years, For now there seems to be no apparent negative impact on the cutthroat fishery in Yellowstone Lake even though Lake Trout may have been present for quite some time. This discovery of a non-endemic fish in Yellowstone Lake has necessitated a mandate to kill all Lake Trout caught in Yellowstone Lake.

Yellowstone Lake has a colorful history, abundant natural amenities, great fishing, hiking, photography, and a dynamic geological landscape unmatched in the world. Whatever the reason for your trip to Yellowstone Lake, you couldnÍt have picked a more interesting destination.

A Few Thoughts On Fishing
"But when I am alone in the half light of the canyon all existence seems to fade to a being with my soul, and memories. And the sounds of the Big Black Foot River, and a four count rhythm, and the hope that a fish will rise. Eventually, all things merge into one, and a river runs through it. The river was cut by the world's great flood and runs over rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs. I am haunted by waters." Sound-bite from a River Runs Through it. The Yellowstone Teton Region fly-fishing is blessed with a plethora of blue ribbon trout waters that host prolific hatches of Mayflies, Caddis Flies and Stone Flies. Dozens of rivers and hundreds of lakes and streams, all world-class fisheries that attract anglers from around the world. The Henry’s Fork, the Snake, the Madison, and the Yellowstone Rivers have been elevated to legendary status by the movies made about them and the books and articles that have been written about them. If you believe what you read, fly-fishing requires the touch of a surgeon and the spirit of a Zen master. Well, it might help but it certainly isn’t required around here. Forget about what you’ve heard about fly-fishing in the past, if you really want to fly-fish all you need are the right tools, proper technique, and a positive attitude. With these essential elements, you can begin to enjoy the sport of fly-fishing in no time. Some time spent with a guide can enhance your skills exponentially in a very short time, as they are all trained to be teachers. A day discovering the best techniques for fly-fishing with a guide on one of our regional rivers or legendary spring creeks gives you the foundation for many years of productive fly-fishing enjoyment of the future. Many regional guides have spent a lifetime fly-fishing the rivers and streams of Yellowstone Teton Region. Their instruction of the best flies, how to read the water, presentation, and all aspects of fishing the Yellowstone region can greatly enhance your fly-fishing experience. For those of you who already know how to fly-fish, or do not want to hire a fly-fishing guide, all you need is a map, the proper seasonal fly selection, and some current fly-fishing advice, all which can be found for the price of a handful of flies at a local fly shop. Most rental shops of the Yellowstone Teton region have drift boats rafts and float tubes for rent for those of you that wish to escape the confines of the bank of your river, lake, or stream, because as we all know, the big one is in the eddy on the far side of the river. Spin-cast fishing is popular around the area also and is a very productive way to wet a line. Although spin fishing doesn’t require the finesse and learning curve of fly-fishing, a guided trip with a guide that knows spin-fishing can really improve our catch rate. Remember to keep in mind to de-barb your hooks to improve your catches chance of survival upon release. We also encourage lure fisherman to cut their treble hooks down to a single hook. The Snake River Drainage is home to a unique subspecies of cutthroat trout known as the Fine-spotted Snake River Cutthroat Trout. This outstanding game fish is indigenous to the Snake River drainage and relies totally on natural reproduction. Having a wild trout fishery with indigenous trout is not something we take for granted and we highly encourage catch and release fishing to protect this valuable resource. The Yellowstone Cutthroat, as the name implies, are native to the Yellowstone River drainage of southwest and south-central Montana and northwest Wyoming. In general, The relation of Yellowstone cutthroat trout to Snake River fine-spotted cutthroat trout is problematic. Early genetic analyses could not distinguish these subspecies, but recent attempts have been more successful. Whether you are fishing for one of the Fine-spotted Snake River Cutthroat our Yellowstone Cutthroat you will find their most endearing qualities is their fondness for feeding on top sipping mayflies flies or attacking stoneflies, drakes, and hoppers. Large dry flies like size eight Turck Tarantulas, Royal Wulffs, Club Sandwiches, and hoppers are all popular and good choices. Size six and even four stone fly patterns sometimes are also effective. Rainbow and Brown Trout can be found throughout the area as well a few sub-species of cutthroat trout, and some of our lakes are home to Kokanee Salmon. Many of our lakes are gifted with giant Lake Trout, but you usually need to be an expert or lucky to get one in the 20 to 50 pound category. Most are taken by trolling with spoons or minnow-like plugs attached to wire-line rigs or downriggers. They can also be taken by bottom fishing with whole or cut fish. In summer they often move to depths of 50 to 100 feet, but in spring and fall you can find them at depths of 20 feet or less. When ice fishing you can catch Lake Trout in hardly any water at all. Many of our lakes are put and take fisheries and are planted by the Idaho, Montana or Wyoming Game and Fish, but most of our rivers and streams are wild trout fisheries and do not receive planted fish. Our wild trout fisheries, due to the law of survival of the fittest, produce a hardier, smarter game fish, and is a resource worthy of protection. Catch and release although not mandatory on many waters is often the practice. Many of the fish of the region are caught and released 40 times per year and if everyone kept their fish there wouldn’t be any here except inferior hatchery fish. I used to keep my big ones because they were such trophies, and I used to keep some to eat until I realized that I can buy a trout for two dollars in the store and that fish in the river provides has a much greater value than two dollars as a recreational resource.

	Chuck Yeager & Guide Mike Lawson - One Fly Fishing Contest Jackson Hole One Fly Fishing Contest • Each year in September, flyfisherman from around the world gather in Jackson Hole Wyoming to participate in one of fly fishing's most unique events. It is a weekend filled with fun, challenges, adventures and of course, the famous Snake River Cutthroat trout. Give the Cutt-slam a try. • If you want to see some breathtaking country, do a little camping and accomplish something that only around 300 people have done, you might want to give Wyoming’s Cutt-Slam program a try.  This year marks the 10th anniversary of the program that recognizes anglers for catching Wyoming’s four subspecies of cutthroats in their native range. Back in the mid-90s, Wyoming fisheries coordinator, the late Ron Remmick, had an idea to try to bring more public awareness to Wyoming’s cutthroat trout and the management efforts benefitting these fish.  The Cutt-Slam was hatched and a program was developed to recognize anglers for making the effort to catch the Snake River, Bonneville, Colorado River and Yellowstone cutthroat subspecies.
Stories
	Fly-fishers go crazy saving flies - by D Dave Strege One fly-fisher stripped his clothes off and swam naked into the river to retrieve his fly that got snagged. Another stood on the shoulders of the guide and used pruning shears to cut down the branch where his fly was lodged. A lucky one hooked a big fish that snapped his line, losing fish and fly, only to wait five minutes before the fly somehow dislodged from the trout's mouth and popped to the surface. He netted it — the fly, that is. What would lead a fly-fisher to go to such extremes to save a fly caught in a tree limb or a log in the riverh.................More
