Department of Fisheries of Canada Vancouver, B. c. September, 1965 ' ' '• CONFIDENTIAL INTRODUCTION That portion of Brit~sh Columbia and the Yukon Territol'Y' situated immediately inland of the Alaska Panhandle gives rise to six major river systems. These are the Alsek, Chilkat, Taku, Whiting, Stikine and Unuk rivers (Figure 1) and there are indi genous to each of these, salmon stocks which originate on the '.·· Canadian side of the international border. Currently, the utilization of these stocks is limited to exploitation by a United States commerc.ial tisherr and bf limited native food fisheries. Precise information.on the size and distribution of' escapements is lacking because of the difficultr of making estimates in turbid glacial streams and because of the remot·eness ot the region. Although the area is relatively inaccessible, roads recently completed, do reach the Nakina River on the Taku system; the Stikine River at Telegraph Creek; the Unuk and the upper Alsek Tatsensheni Rivers. Also, mineral developments on the Stikine, Unuk and Alsek~Tatsensheni Rivers will probably provide increased . ' access to the area in the not too dis.tant future. River transport is possible on the Stikine, as tar upstream as Telegraph Creek, and on the Taku as tar upstream as Tulsequah. Al~hough most of the area behind the Panhandle is readily accessible by fixed-wing aircraft, access to certain areas is limited by the lack of suitable landing facilities. The only centers of population in the area are Telegraph Creek on the Stikine River and Haines Junction on the Alsek River. .. , ?1 ~. I ,I ' -... '\ \ \ \ \ ·~, ~~......,,, \ I I I' TEWA.!!J.'

Figure I The Alaska Panhandle region showing the drainage areas of the six 'Streams which originate on the Canadian side of the International border between British Columbia and ·the Alaska Panhandle. .. J -2- 0 The native population in the Pacific drainage area of the Yukon and northwestern British Columbia is limited to twenty families at Telegraph Creek and the Champagne Indian Band who travel to Klukshu on the Tatsensheni River to fish. Natives from Atlin also fish at Tulsequah on the Taku River, but at irregular intervals. The following presentation comprises a brief summary of the information available on the size and escapement distribution of salmon stocks which originate on the Canadian side of the international border between British Columbia and the Alaskan Panhandle. Also included are statements regarding the feasibility of developing Canadian fisheries on these systems. ALSEK RIVER The Alsek River originates in the southwest part of the Yukon Territory and flows southwesterly through British Columbia · and through about 40 miles of the Alaska Panhandle to empty into Dry Bay on the Pacific Ocean. The Alsek River is a composite of two rivers or approximately equal size; the Tatshenshini and Alsek rivers which unite to form the mainstem Alsek River about ten ( miles above the international boundary (Figure 2). Most ot·the 8-10,000 square miles of drainage area ot the Alsek River System is located in Canada. The river originates behind the Coast Range, is largely glacial fed and is therefore characterized by high midsummer flows and turbidities. ( YAKUTAT PA t:IFlt: OCEAN ALSEK RIVER WATERSHED I j SCALE Figure 2 ../ -3-. 0 A glacier causes an obstruction on the Alsek River at a point 3o·to 35 miles above the bounda.%"1 and. possibly tor this reason, salmon are absent from the Alsek River and its tributaries above that point. This means that all known salmon spawning is restricted to the Tatshenshini section or the system. SALMON STOC"!r5 Size and Distribution of Escapement All five species ot Pacific salmon are indigenous to the Tatshenshini River. Chinook Salmon .Spawning chinooks have been observed in a number of streams tributary to the Tatshenshini. These are the Blanchard, Takanni, Klukshu, Silver and Takhanne rivers. Actual escapement figures for chinook salmon to this system are unknown although the commercial catch figures give some indication of stock size. (See Table I) Sockeye Salmon Observations of spawning sockeye salmon have been report ed in; .the Klukshu River and Lake as well as Village Creek. The escapement to the Klukshu system approximates 2 1 000 sockeye salmon annually; the escapement to Village Creek is unknown. Coho Salmon Coho salmon spawning has been reported from a number ot tributaries or the Tatshenshini River. Among the larger -. coho producing tributaries are.the Klukshu and Takhanni . ,~ ·4- rivers and Village Creek. There are no actual estimates of escapement tor co~o salmon available. Pink and Chum S~on No reports are availal)le on the spawning esc.apement ot these .sp.eci·ea, but the minor catches reported from the u.s. fisherr·indioate that the total stocks are insigni .t'icant. Commercial Catch The U.S. commercial oatoh tor .the period 1951 to 1954, as shown in Table I, is based primarily on sockeye and coho salmon and totals approximately 43,000 pieces annually. More recent catch data was not available. TABLE I. Annual Salmon· catches and Number of Gillnets Operating in the ·Alsek River - Dry: Bay Fishe17 in the Years 1951 to 19~4· . Sockeye Chinook .

The annual catch averages 2,000 sockeye, 100 chinooks and 100 coho. Sockeye are captured by a trap placed in the river at the outlet of Kl.ukshu Lake while chinooks and coho are gaffed in the Klukshu River downstream from the trap site. Fo:rmerly, a native food fishel'J was located near the now abandoned village of Dalton Post. Timing of Migration Chinook salmon enter the river from April through June; the sockeye migration occurs during July and August; and coho salmon are present from late July to .early October. FISHING POTENTIAL IN CANADIAN WATERS Although precise infonnation regarding the physical character of the river is ~ot available, reports indicate that the river near the inte:rnational border is broken into numerous channels;. is not navigable; and would not lend itself to drift- net or set-net fishing. Although the use ot beach-seines, fish-wheels or traps might be possible in the lower section or the river, the small size of the stocks, the extended migration · period and the inaccessibility of the area would seem t_o rule out an economic commercial fishe17 in that region. Although there is a possibility that small numbers of sockeye, .coho &J?-d chinook salmon could be harvested in the vici.nity of Dalton Post, in ,the Yukon Territory, any fishery at this point would serious.ly affect the catch ot. salmon by the . native food fishery on. the Kllikshu River. ) 0 -6- CHILKAT RIVER The Ohilkat River Basin is located mainly in Alaska· and only a small portion ot six tributaries originate in British Columbia (Figure 3). Of these, salmon have been observed in the Kl.ehini, Kelsa11·and Tahini Rivers but the reported populations have been small. SALMON STOCKS Size and Distribution of Escapement Although the Chilkat River on a system basis, is a valuable salmon producer, particularly ot chum and coho, the major and predominate part or the production arises from ·the Alaska ·~ ~V segment of the system. Spawning in the Canadian portion of the system is restricted to small populations of coho and chum salmon in the Tahini River; a small stock of chum salmon in the Klehini; and small populations of chum and sockeye in the Kelsall. Sockeye apparently do not extend,as far inland as Kelsall Lake, which at 2.4 square miles, is the largest lake on the Canadian segment of the Chilkat River System. Commercial Catch The actual U.S. commercial catches tor this s7stem:are not published bu.t it is known that considerable numbers of chum salmon. are harvested. Canadian Native Food Fishery There is no Canadian native food fishery on the Chilkat River System a " CHILKAT RIVER WATERSHED ..._, u-J ICM.a ' ' Figure 3 . ' =~ -7- FISHING POTENTIAL IN CANADIAN WATERS In summary, the salmon populat1oll$ indigenous to the Canadian segment or the Chilkat System are small; the general region is extremely inaccessible; and the small size and steep gradient of the streams on the Canadian side or the bo~der would necessitate the use ·ot specialized fishing equipment. On this basis it would seem that no potential exists tor a Canadian fishery- or any 'tJ'pe. TA.KU RIVER The Taku River originates in the high plateau country ot northwestern British Columbia and except tor. that portion of "~ the drainage associated with a 12-mile section of the river located between the head of Taku Inlet and the international border, the entire drainage area, which totals 6,400 square miles, is located within British Columbia (Figure 4).
