In 1995, at the suggestion of friends leading the Mongolian Biodiversity Project, Jeff Vermillion organized a fall expedition to explore the rivers of Mongolia for trophy Taimen. The results far surpassed his expectations. During the 1995 exploratory, Jeff and Mongolian outfitter, Hovsgol Travel Company, fished several rivers in Mongolia which held large Taimen populations. Unlike the Taimen Rivers in Siberia and other parts of Mongolia, these rivers produced Taimen in the 50 inch plus range on a dry fly.
Since that time, Sweetwater Travel has built two lodges in the Eg Ur watershed and have spearheaded the first international Taimen conservation project. With the help of the World Bank, they have succeeded in protecting the Taimen in this critical watershed. In fact, in 2010, they landed the biggest Taimen they have ever landed, a new world record. In 2011 and 2012 they did not break the world record again, but ended up landing extremely good numbers of big fish during both seasons. The camps are located on nice stretches of river in the remote outback of Mongolia. They are strategically positioned to enable fishermen to access over 90 combined miles of river by jet boats. These are isolated wilderness facilities with very limited access to the outside world, which enhances the fishery and the adventure experience. Guests have provided glowing reports about the standard of service and level of comfort at the camp. Each camp is equipped with a dining lodge, bathhouse and shower facility.

Mongolian Gers
Fishermen will stay in traditional Mongolian gers which are felt tents wrapped around a collapsible wooden frame. They are 9 feet high and 18 feet in diameter, much larger than standard wall tents, and are equipped with framed full-length single beds, ample room for storing gear, and an area to sit down and relax by a wood stove. Each ger accommodates two fishermen.

Food is prepared by an experienced Mongolian kitchen staff, and generally clients have been quite pleased with the food. Daily meals include a wide range of traditional Mongolian and American dishes. After a soup course, grilled sheep, beef, chicken and fish prepared in a variety of fashions may accompany side dishes of steamed carrots, beets, cabbage, potatoes and other vegetables. Mixed salads are served nightly. All food is prepared with properly filtered water, so there is no need to pack bottled water.

The fishing

The rivers in the region to be fished are a fly fishermans dream. They are clear and easy to wade. The banks are easy walking and range in size from 40 to 120 feet wide. It is hard to imagine that a fish as large as the Taimen can live in these waters. In fact the largest Taimen yet, a 60 inch fish, was taken on a mouse pattern in a particularly narrow stretch of river. Water conditions in Mongolia are generally quite stable; however, if the headwaters of our rivers do receive a heavy rain, off-color water conditions are possible. In the past, the camp and guides have found that fishing is still possible in off color conditions and that the rivers generally clear quickly. Taimen fishing in Mongolia is a lot like fly fishing for oversized Atlantic Salmon or Steelhead on a dry fly. It is similar because you are fishing for Taimen in the current and, consequently, need to keep your fly riding high in the water. By riffle hitching a mouse, large muddler or streamer, fishermen can keep their fly twitching through the surface film. Taimen have a true weakness for flies presented in this fashion. For fly fishermen, though, getting your fly to ride properly is the least of your problems. Keep in mind that some of these fish are 4 5 feet long. Now imagine a fish that large visibly chasing down your fly. In some cases Taimen will come completely out of the water and hit your fly on their way back into the water. Other times Taimen will simply follow it slowly with their tail out of the water some four feet behind the fly and attempt to gulp it in slowly like a Montana cutthroat.

The guides
The guides at both camps consist of highly experienced guides, who are professionals and well respected in the fly fishing world. They are very personable and will do everything possible to make your fishing vacation in Mongolia a memorable one.

The Boats
Fishermen will fish from 18 ft. aluminum semi – v Lowe boats powered by 55 hp Mariner jet units with two fishermen to a boat. Atlantic salmon-style drops are possible for fishermen that enjoy a break from wading. Each boat is equipped with tools, an emergency kit, and a cooler for food and drinks during the day.

The Fish
Taimen, Lenok, Arctic grayling, and Amur Pike are all present in the region to be fished. The camp requires that all fishermen fish with barbless hooks. Fishing is fly fishing catch and release only.
Taimen (Hucho Taimen) are an especially ferocious fish that can attain weights of well over 100 pounds. In Russia, there are reports of Taimen up to 200 pounds. On the rivers to be fished in Mongolia, the average Taimen is around 32 inches and roughly 10 pounds. However, almost every week, fishermen will have chances on fish over 50 inches. Catch and release is required on all Taimen. Taimen are an aggressive fish that will eat anything they can fit in their mouth. During the 1996 exploratory, one of the guides demonstrated how Mongolians fish for Taimen with prairie dogs. After shooting a prairie dog and rigging the bait, the guide cast out his prairie dog and reeled it back as fast as possible. The result was incredible. A 45 inch Taimen came out of the water and slammed the bait. Fortunately for fly fishermen, a simple mouse pattern will suffice in bringing these huge fish to the surface. Streamer patterns on either a sink tip or floating line also work well. In the past, fishermen have resorted to wets after refusals on mice, poppers, etc. Lenok (Brachymstax lenok) are the Mongolian equivalent of a trout. In appearance they look like a rainbow trout with the mouth of a tarpon. These fish rely on the prolific caddis and mayfly hatches, and terrestrials such as grasshoppers and crickets. Lenok average 18-20 inches long and are very entertaining on lighter fly rods. Larger Lenok will dine on mice patterns and streamers. As one fisherman, later dubbed as Lord Lenok, put it: Why on earth would you cast gerbil flies for a fish like Taimen that are so huge and difficult to bring in when you can sight cast normal dries to 20 28 inch Lenok? Arctic Grayling (Thymallus arcticus) are, to put it simply, scared. The rivers are full of grayling of all sizes. During hatches, two things become apparent; one, the rivers of Mongolia are full of 12 18 inch grayling; two, Taimen consider grayling an arctic delicacy. Still, like the Lenok, they provide good sport and action on dries. Amur pike are present in Mongolian rivers and lakes. In fact they are reported to reach well into the 30 pound range. From our experience, though, we have not had great success on this species.
