The Alagnak Wild River is a truly primitive environment with no federally-maintained public facilities. The NPS imposes no operating hours or seasonal restrictions. Access to and movement within the Alagnak Wild River corridor, however, may be limited or restricted at any time depending upon prevailing weather conditions.

You might float the Alagnak River today and hardly see another soul. But don’t be fooled—this resource-rich area has been home to human communities for thousands of years.

Archeologists surveying the river have found sites belonging to the Paleoarctic tradition (9,000 to 7,000 years ago). The oldest radiocarbon dated sites are about 2,300 years old. From these ancient campsites and villages all the way to modern fish camps, the Alagnak bears witness to the people who lived there. Prehistoric times were a productive time to live along the Alagnak. There was a substantial population of people living on the river’s bounty. Some inhabitants lived in settlements as small as 4 dwellings, while others lived in much larger villages with as many as 69 dwellings. Tiny chipped stone projectile points have been found at sites dating to 2,000 years old along the Alagnak Wild River. Archeologists believe that these are evidence of increased hunting with bow and arrow technology.

Modern Alutiiq people from Levelock, Iguigig, Naknek, and other villages make use of the Alagnak area for subsistence fishing, hunting, berry picking, and firewood gathering.

In June 1927 pilot Russell Merrill of Anchorage Air Transport flew a Travel Air to Lockanok cannery at the mouth of the Alagnak Wild River. This first airplane landing in the Bristol Bay region would effectively lead to a new era of air transport for this formerly inaccessible part of Alaska.

The headwaters of the Alagnak Wild River lie within the rugged Aleutian Range of neighboring Katmai National Park & Preserve. Meandering west towards Bristol Bay and the Bering Sea, the Alagnak traverses the beautiful Alaska Peninsula, providing an unparalleled opportunity to experience the unique wilderness, wildlife, and cultural heritage of southwest Alaska.

In the local language, the word Alagnak means “making mistakes.” According to a life-long area resident, “the channel is always changing, causing mistakes and getting lost.” Every year the river changes and branches, which is why it is known locally as “Branch River.”

There are a variety of vegetation along the Alagnak such as spruce, willows and many types of berry bushes (salmon berries, blackberries, blueberries, and cranberries). Fiddlehead ferns, wild celery, and sourdock are also present and collected by subsistence users. During a summer field survey, a total of 523 specimens were collected, recorded, and pressed. Approximately 130 species are new records for the area. A number of discoveries present significant range expansions of species. For example, a population of Dupontia fisheri, a tundra grass of northern and northwestern Alaska and northern Siberia, was found at Swikshak Lagoon over 200 miles east of its previously known range. Additionally, it is the first time it has been recorded in a woodland marsh in Alaska. Carex filifolia, a sedge, was found on a mountainous ridge above Swikshak Lagoon, approximately 450 miles to the southwest of its known range.

The Alagnak Wild River’s abundant wildlife and Class I-III rapids offer exciting opportunities for sightseers and adventure-seekers alike. Whether cruising, paddling, or floating, however, anglers will enjoy some of the most attractive sport fishing in the world. With significant populations of rainbow trout, arctic char, grayling, and sockeye and king salmon, the Alagnak has become the most popular destination for sport fishing in Southwest Alaska.

Sport fishing, commercial fishing, and subsistence fishing all occur on the Alagnak. All types of fishing are reliant upon the success of the salmon life cycle. The increasing sport fishery on the river is a topic of concern to many subsistence users and other local residents. Subsistence fishing on the Alagnak is for local rural residents only. During the summer camps are set up on the river and fish are gathered for smoking, salting, canning and freezing. Salmon harvested in the summer is the primary food source for subsistence users year round.

Meandering down the braided Alagnak, serenity and wildlife viewing opportunities abound for those lazily floating the river, while Class III rapids offer exciting trips for rafters. Rafting trips generally begin at Nonvianuk Lake or Kukaklek Lake, both of which are easily accessible via float plane. Rafters should coordinate their pick-up location and date with their transporter and should plan a fly-over of the river to scout for potential hazards and river conditions. There are many river sections suitable for take-out along the lower 30 miles of river. Parties being picked up near the Cutbank (Estrada’s camp) should be aware that this is private property; therefore, rafters should take out downstream or on the opposite side of the river. Please respect all private property along the Alagnak River.

Sport hunting, subsistence hunting, and trapping are authorized by the Alaska National Interest Lands Conservation Act (ANILCA) within the Alagnak Wild River corridor. Hunting is allowed in accordance with Alaska Department of Fish and Game (ADF&G) regulations for Game Management Unit 9C. Any wildlife killed in defense of life or property must be reported to ADF&G within 15 days. The meat of a game animal that you have legally taken becomes your property, but you may not kill another wild animal to protect the meat unless the meat is critical for your livelihood or survival.

Subsistence fishing on the Alagnak is for local rural residents only. During the summer camps are set up on the river and fish are gathered for smoking, salting, canning and freezing. Salmon harvested in the summer is the primary food source for subsistence users year round.

The Wild and Scenic Rivers Act of 1968 has fifteen management principles that river managers must adhere to; one of the principles is water quality. Part of the reason the Alagnak was designated as a “Wild” river was due to the fact that it was starting off at such a healthy, pristine level. To retain the “Wild” status over time that level of purity will have to be documented and maintained.

Consistent with the Clean Water Act, water quality in wild, scenic and recreational river areas will be maintained or, where necessary, improved to levels which meet Federal criteria or federally approved State standards for aesthetics and fish and wildlife propagation. River managers will work with local authorities to abate activities within the river area which are degrading or would degrade existing water quality.

The Wild and Scenic Rivers Act declared it a policy of the United States that “selected rivers of the Nation which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural, or other similar values, shall be preserved in free-flowing condition, and that they and their immediate environments shall be protected for the benefit and enjoyment of present and future generations.” By designating the Alagnak River, Congress mandated that the Alagnak Wild River be administered in such a manner as to protect and enhance the values which caused it to be included in said system without, insofar as is consistent therewith, limiting other uses that do not substantially interfere with public use and enjoyment of these values. Part of the reason the Alagnak was designated as a “Wild” river was due to the fact that it was starting off at such a healthy, pristine level. To retain the “Wild” status over time that level of purity will have to be documented and maintained.

Erosion of riverbanks from river currents and waves is a natural process. However, increased wave action due to motorboats has become a serious concern over the years with an increase in visitation to the Alagnak Wild River. Actively eroding and denuded riverbanks are especially vulnerable to further wave action as high banks composed of loose sand and gravel are undercut. Visitors using motorboats can help reduce continued erosion by significantly slowing their craft in areas where erosion is evident.

Weather in the Bristol Bay area tends to be cool, cloudy, and misty with frequent rain and wind. Day temperatures in the summer range between 50 and 60 degrees Fahrenheit while night temperatures may drop to 40 degrees Fahrenheit. The surface of the Alagnak freezes in the winter, but water continues to flow. Frozen overflow creates thin layers of dangerous ice which pose a hazard for those who attempt winter river travel. Whatever the season, weather conditions may prevent airplanes from flying in, so parties should be prepared for at least one extra day on the river. Wearing layers of clothing makes it easy to regulate your body temperature. Weather in all areas of the Alaska Peninsula can be both sudden and severe. Be prepared for extreme conditions at all times of the year and have the wisdom to alter your plans if necessary.

Current Weather

Visitors to the park should have rain gear including water-proof foot gear and clothing that retains warmth when wet, such as wool or synthetics. An insect-proof head net is also a must. Those camping should bring the necessary gear for wilderness. A good camping/backpacking list is: good quality tent with rainfly, sleeping bag, sleeping mat, matches, layered clothing, food (more then you need in case of delays or problems), water filtering system, collapsible water carrier, GPS, compass, topographical map, flashlight with extra batteries, campstove, fuel, bear proof container for food and perfumed items, signal whistle or mirror, first-aid kit, sunglasses, sunscreen, insect repellent, knife or multiuse tool, good hiking boots or water-proof footwear, repair kit, backpack, cooking pots, plastic bags to carry out garbage, tarp and possibly waders.

Campers are encouraged to make known their itinerary information. Visitors should leave itinerary information with a friend or family member. Be sure to include float plan details, the name of the trip leader, the air taxi operator’s name and contact information, type and color of equipment/clothing used, and anticipated date of return. The NPS will not initiate a search for an individual or group unless they are reported overdue. Alagnak users are also encouraged to submit the same information in a “Backcountry Planner,” available free-of-charge at the King Salmon Visitor Center. For their own safety and enjoyment, and for the continued health of the Alagnak environment, campers are encouraged to practice the Leave No Trace Principles of outdoor ethics.

The Alagnak is bear country! You can encounter substantial populations of brown bears in any area. It is critical that you know how to behave around bears. Avoid close encounters by remaining aware of your surroundings at all times. In order to minimize human-bear conflicts, it is critical that campers store food, trash, and any odorous items in bear-resistant containers (BRCs, or “bear barrels”). A limited supply of BRCs are available for temporary use, free-of-charge at the King Salmon Visitor Center. Hanging food is not encouraged as trees of appropriate height will not be available in what is essentially treeless tundra. Check out our Wildlife Precautions page for further safety tips.

Much of the land around the river is Native corporation land or private allotments, and most cabins are not on NPS land. Please do not enter private land without permission. If you encounter a cabin, historic debris, or an archeological site, please enjoy it, explore and take pictures! Resist the temptation to take artifacts or otherwise alter what you find. Your good stewardship will help preserve these historic places for future generations.

River Conditions will vary based on the season, amount of rainfall and temperatures. Generally water levels will be lowest in the spring and will increase as spring rains begin and snowmelt occurs in the high country. Water levels usually peak in July and will normally begin to recede in the fall. The surface of the Alagnak freezes in the winter, but water continues to flow. Frozen overflow creates thin layers of dangerous ice which pose a hazard for those who attempt winter river travel.

Due to heavy rainstorms and prolonged winds from the east can drive water out of Kukaklek and Nonvianuk Lakes and consequently increase water volume and velocity downstream. During periods of high water, it is possible to float the river in 1-2 days, but the conditions may make it difficult to find suitable camping sites. High water often results in increased turbidity and reduced fishing success, and may also increase the difficulty of the rapids on the upper Alagnak. Low water conditions can make travel difficult due to increased numbers of exposed rocks.

Wear Personal Floatation Devices (PFDs) and carrying self rescue equipment, including a throw rope. Survival gear and signaling devices are recommended. Extra warm clothing and sleeping bags should be packed in waterproof bags. Know the signs of hypothermia and be familiar with proper treatment techniques.

Hypothermia is the critical lowering of the body’s core temperature and is signaled by shivering, numbness, slurred speech, loss of coordination, drowsiness and exhaustion. Avoid hypothermia by eating plenty of high-calorie foods, drinking plenty of water and staying dry. Layer clothing appropriately for your level of activity to minimize sweating.

Firearms are permitted within the Alagnak Wild River corridor and in the adjacent Preserve portion of Katmai National Park and Preserve.

Wildlife is an important attribute of the Alagnak River, which is inhabited by a wide diversity of species typical of southwest Alaska. Large populations of brown bears are attracted to the area to feed on salmon spawning in the river. The Alagnak provides critical bear habitat during the summer and fall. Moose are attracted to riparian habitat, including the Alagnak River, during all four seasons. Most of the Alagnak River drainage west of Kukaklek and Nonvianuk Lakes provides winter habitat for caribou and moose. Furbearers found along the river include beaver, lynx, mink, otter, fox, wolverine, and occasionally wolf.

Other wildlife present is birds and fish. It is a great area for bird watching. Birds include tundra swans, double-crested cormorants,Red-throated Loon, Common Loon, Horned Grebe, northern fulmar, the osprey, bald and golden eagles, Peregrine Falcon, and black-bellied plovers, just to name a few. Fish species on the Alagnak are: king salmon, silver salmon, red salmon, chum salmon, rainbow trout, char, grayling, northern pike, Aleutian sculpin, slimy sculpin, Alaska blackfish, three spine stickleback, Japanese lamprey, round whitefish, and nine spine stickleback.

The life cycle of salmon vividly expresses the significance of one element within an ecosystem. Salmon are born in freshwater and remain there as long as 2 years until they are large enough to begin their long journey downstream to ocean waters. Salmon reside up to 3 years in the saltwater where they grow to be large fish with a silver sheen. Each summer, the five species of Pacific salmon return to their birthplace in the Alagnak River to spawn and die. As they migrate upstream by the hundreds of thousands, the salmon undergo incredible morphological changes. By the time a male sockeye salmon reaches its destination, it has turned a brilliant red and developed a distinctive humped back. Through this remarkable journey, salmon provide nutrients to support virtually every animal and plant species that call the Alagnak home. For example rainbow trout, Dolly Varden, char, and arctic char eat salmon eggs, juveniles and decaying salmon. As the carcasses decompose, they supply nutrients causing insect populations to thrive. Consequently, even the arctic grayling, a fish that eats primarily aquatic insects, benefits from the presence of salmon. In addition, many other species along the Alagnak such as the bald eagle and the Alaskan brown bear flourish as a result of the salmon’s extraordinary migration. Therefore, salmon populations must be carefully managed to ensure a healthy future for the Alagnak Wild River.

Do not feed or harass the wildlife. Since there are bears, moose and other wild animals frequently present along the river, please see Wildlife Precautions page for further information.

There are no fees for using the river itself.

Primitive camping is available, adding to your adventure trip. Permits are recommended for users and are available at no charge at the King Salmon Visitor Center.

Katmai National Park and Preserve, Aniakchak National Monument and Preserve and Becharof National Wildlife Refuge are a couple hundred miles awayfrom this river.

Charter flights are available from Anchorage and King Salmon or access via power boat from any of the villages along the river.
