  • Bald eagles (Haliaeetus leucocephalus) sit on the bank of the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska. One of the bald eagles extends his one wing behind another bald eagle as it sits on a log. <br />
<br />
Tender moment or just a stretch? While it is easy to anthropomorphize that these two bald eagles are sharing a tender moment, most likely the eagle is simply stretching or cooling off. Bald eagles do not sweat so to control their body temperature they often extend their wings. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world. <br />

Recently, Constantine Metal Resources Ltd. of Vancouver, British Columbia along with investment partner Dowa Metals & Mining Co., Ltd. of Japan have begun exploration for a potential site of a copper and zinc mine in the Klehini River/Chilkat River watersheds. Some local residents and environmental groups are concerned that a mine might threaten the area’s salmon. Of particular concern is copper and other heavy metals, found in mine waste, leaching into the Klehini River and the Chilkat River further downstream. Copper and heavy metals are toxic to salmon and bald eagles.

  • Bald eagles (Haliaeetus leucocephalus) soar together in what is known as a kettle high above the alluvial delta area at the confluence of the Tsirku and Chilkat Rivers in the Alaska Chilkat Bald Eagle Preserve. It was estimated that there were over 100 bald eagles in the swirling kettle. During November and December several thousand bald eagles come the confluence near Haines, Alaska because of the availability of spawned-out salmon and open waters. The open water is due to a deep accumulation of gravel and sand that acts as a large water reservoir whose water temperature remains 10 to 20 degrees warmer than the surrounding water temperature. This warmer water seeps into the Chilkat River, keeping a five mile stretch of the river from freezing as quickly as other rivers in the area. The 48,000 acre area was designated as the Alaska Chilkat Bald Eagle Preserve in 1982.

  • Scott Clem, a student from Auburn University, fishes for salmon at sunset on the Chilkoot River outlet from Chilkoot Lake near Haines, Alaska. The river offers some of the best salmon fishing in Southeast Alaska, with four salmon runs, starting in mid-June and ending in mid-October. The area is part of the Chilkoot Lake State Recreational Site located at the head of the Lutak Inlet in the Lynn Canal. It is managed by Alaska State Parks. In the upper reaches of the Chilkoot River Valley (not pictured) Alaska Power and Telephone Company (AP&T) proposes to dam the outlet of Connelly Lake, a high alpine lake above the Chilkoot River, for a hydroelectric project. Water from Connelly Lake would be delivered down the mountain to a powerhouse near the Chilkoot River into which the lake water would be discharged. Environmental concerns include the impact construction and project operation would have on fish spawning and rearing habitat (water turbidity issues), and bald eagles. Some of the main features of the proposed Connelly Lake project would be located in the Alaska Chilkat Bald Eagle Preserve and the Haines State Forest. The Connelly Lake Hydro Aquatic Studies Report for 2012 prepared by the Shipley Group for AP&T states that according to the Alaska Department of Fish and Game, 41 percent of the sockeye salmon in the upper Lynn Canal come from the Chilkoot River with 25 percent of those salmon spawning in the Chilkoot River drainage above Chilkoot Lake. The value of the fishery is estimated at more than $1,000,000 annually. AP&T wants to build the project to replace the undersea cable that supplies Haines with electricity from Skagway.

The Chilkoot River outlet of Chilkoot Lake offers some of the best salmon fishing in Southeast Alaska. Four salmon runs are an open invitation for bears to feast on the spawning salmon. At times, the Chilkoot River Corridor has some of the highest bear activity in the state. The Chilkoot River corridor area is extremely narrow with room for an equally narrow road with few pullouts for tourists and fisherman causing traffic and congestion. This creates a serious conflict between humans and bears.<br />
<br />
Care must be taken by visitors to the area to protect themselves and the bears. Bear and human conflicts have been increasing in recent years to the point that a special human free zone was established to give bears access to the river. In addition a bear viewing platform is under development to provide a safer location for visitors to view bears feeding in the river. The area is part of the Chilkoot Lake State Recreational Site located near Haines, Alaska at the head of the Lutak Inlet in the Lynn Canal.<br />
<br />
The Chilkoot River ranks second in popularity for Southeast Alaska freshwater sports fishing. The area is also an important cultural area for the Tlingit people and site of a culture camp.<br />

  • Connelly Lake (center) is a 90-acre alpine lake near Haines, Alaska that drains into the Chilkoot River. Connelly Lake is the focus of a proposed $32 million, 12-megawatt hydroelectric project by Alaska Power and Telephone Company (AP&T). AP&T proposes to build a dam at the outlet of Connelly Lake that would create a 160-acre reservoir and a 6,200-foot-long penstock down the side of the mountain where water would be delivered to turbine generators located in a powerhouse near the Chilkoot River into which the lake water would be discharged. Some of the main features of the proposed Connelly Lake project (for example portions of the penstock, the powerhouse, access roads, and the transmission line) would be located in the Alaska Chilkat Bald Eagle Preserve and the Haines State Forest. Concerns include the impact construction and project operation would have on fish spawning and rearing habitat, and bald eagles. The eagles rely on the salmon that use the Chilkoot Valley in the fall and early winter when they are attracted to late spawning salmon runs. A hydro aquatic studies report prepared by the Shipley Group states that according to the Alaska Department of Fish and Game, 41 percent of the sockeye salmon in the upper Lynn Canal come from the Chilkoot River with 25 percent of those salmon spawning in the Chilkoot River drainage above Chilkoot Lake. The value of the fishery is estimated at more than $1,000,000 annually. AP&T announced in June 2013 that it was putting the project on hold citing difficulty securing funding from the Alaska Energy Authority and the lack of community support. Despite these setbacks AP&T says that it not abandoning pursuing the project. In early September 2013, the Haines Borough announced that it was exploring possibly filing for a preliminary permit now that the project was no longer being pursued by AP&T. This photo of the ice and snow covered Connelly Lake was taken in mid-July.

Connelly Lake is the focus of a proposed $32 million, 12-megawatt hydroelectric project by Alaska Power and Telephone Company (AP&T). AP&T proposes to build a dam at the outlet of Connelly Lake that would create a 160-acre reservoir and a 6,200-foot-long penstock down the side of the mountain where water would be delivered to turbine generators located in a powerhouse near the Chilkoot River into which the lake water would be discharged. Some of the main features of the proposed Connelly Lake project (for example portions of the penstock, the powerhouse, access roads, and the transmission line) would be located in the Alaska Chilkat Bald Eagle Preserve and the Haines State Forest. Concerns include the impact construction and project operation would have on fish spawning and rearing habitat, and bald eagles. The eagles rely on the salmon that use the Chilkoot Valley in the fall and early winter when they are attracted to late spawning salmon runs. A hydro aquatic studies report prepared by the Shipley Group states that according to the Alaska Department of Fish and Game, 41 percent of the sockeye salmon in the upper Lynn Canal come from the Chilkoot River with 25 percent of those salmon spawning in the Chilkoot River drainage above Chilkoot Lake. The value of the fishery is estimated at more than $1,000,000 annually. AP&T announced in June 2013 that it was putting the project on hold citing difficulty securing funding from the Alaska Energy Authority and the lack of community support. Despite these setbacks AP&T says that it not abandoning pursuing the project. In early September 2013, the Haines Borough announced that it was exploring possibly filing for a preliminary permit now that the project was no longer being pursued by AP&T. The large lake in the background is Chilkoot Lake.

  • A lone fisherman fishes at the outlet of Chilkoot Lake at the Chilkoot Lake State Recreation Site near Haines, Alaska. <br />
<br />
The Chilkoot River outlet of Chilkoot Lake offers some of the best salmon fishing in Southeast Alaska. Four salmon runs are an open invitation for bears to feast on the spawning salmon. At times, the Chilkoot River Corridor has some of the highest bear activity in the state. The Chilkoot River corridor area is extremely narrow with room for an equally narrow road with few pullouts for tourists and fisherman causing traffic and congestion. This creates a serious conflict between humans and bears.<br />
<br />
The Chilkoot River ranks second in popularity for Southeast Alaska freshwater sports fishing. The area is also an important cultural area for the Tlingit people and site of a culture camp.

  • Snow blankets the Chilkoot River valley near Haines, Alaska. The Chilkoot River corridor between Chilkoot Lake and Lutak Inlet of the Lynn Canal is a popular sport fishing spot and a culturally important Tlingit historic site. The river area is also popular with grizzly bears who also come for the salmon who spawn in the Chilkoot River. While this concentration of bears makes for exciting bear viewing for visitors, the narrow corridor in which humans and bears must pass can lead to dangerous encounters. The Alaska Legislature has approved $1 million for a bear-viewing platform aimed at reducing encounters between bears and visitors to the scenic corridor. This area is part of the popular Chilkoot Lake State Recreation Site.

  • The Chilkoot River outlet of Chilkoot Lake offers some of the best salmon fishing in Southeast Alaska. Because of the salmon spawning in the Chilkoot River bears frequent the river to feast on the salmon. Care must be taken by visitors to the area to protect themselves and the bears. Bear and human conflicts have been increasing in recent years to the point that a special human free zone was established to give bears access to the river. In addition a bear viewing platform is under development to provide a safer location for visitors to view bears feeding in the river. The area is part of the Chilkoot Lake State Recreational Site located near Haines, Alaska at the head of the Lutak Inlet in the Lynn Canal.

  • A bald eagle (Haliaeetus leucocephalus) flies with a salmon carcass past ice covered trees sparkling in the golden light of sunrise at the confluence of the Tsirku and Chilkat Rivers in the Alaska Chilkat Bald Eagle Preserve. During November and December several thousand bald eagles come to the alluvial delta area at the confluence of the Tsirku and Chilkat Rivers near Haines, Alaska because of the availability of spawned-out salmon and open waters. The open water is due to a deep accumulation of gravel and sand that acts as a large water reservoir whose water temperature remains 10 to 20 degrees warmer than the surrounding water temperature. This warmer water seeps into the Chilkat River, keeping a five mile stretch of the river from freezing as quickly as other rivers in the area. The 48,000 acre area was designated as the Alaska Chilkat Bald Eagle Preserve in 1982.
