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.
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 sportfishing 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 sportfishing in Southwest Alaska.
Camping
The National Park Service maintains no campgrounds in the Alagnak Wild River; all camping is primitive.
Fishing
The Alagnak?s extraordinary rainbow trout, char, grayling, and abundant salmon are some of the most attractive sportfish in the world, and the river has become the most popular fly-in fishing location in all of southwest Alaska. Although the fishing is exceptional, these prized sportfish are still vulnerable to overfishing. The Alaska Department of Fish and Game (ADF&G) carefully monitors the populations to ensure that the present regulations maintain the long-term stability of the Alagnak sport fishery. Visitors intending to fish should become familiar with these regulations specific to the Bristol Bay area.
Paddling
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.
Whatever their chosen speed, boaters 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 visitors are also encouraged to submit the same information in a "Backcountry Planner," available free-of-charge at the King Salmon Visitor Center.
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.
River Conditions
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.
Water Levels
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.
Climate
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.
Directions
Located on the Alaska Peninsula, 290 miles southwest of Anchorage, the Alagnak Wild River is inaccessible by road.
The Alagnak may be directly accessed via air taxi flights chartered from Anchorage, King Salmon, Iliamna, Kodiak, Soldotna, Homer, or other nearby Alaska towns and villages. Regularly scheduled commercial flights to King Salmon (AKN), which serves as NPS administrative headquarters and the starting point for most Alagnak adventures, are available from Ted Stevens Anchorage International Airport (ANC) via PenAir and Alaska Airlines.
