It is mainly a compilation of basic data for reference and for further analysis tqker warranted, although brief analysis may be contained herein. Nine counting traps were in operation in 1960 (six ir 1959). These were located at Indian River, Salmon Brook (Gander Rieer)„ Salmon River (Bay D'Espoir), Lower Terra Nova River, Tipper Terre Nova River, Rattling Br ok (Norris Arm), Tote Brook end Cerr I on Greet Rattling Brook, end at Bishop's Falls dam on the Exploits River. The counting trap at Middle Brook (r-ambo) was discontinued in 1960 after four years of successful operation (the fishway was completed in November 1954 arid a counting trap installed in 1956). Meanwhile, three new counting traps were added in 1960 - one at salmon River (Bay D'Espoir) to ascertain the salmon run to that river, the site of a proposed hydro development. Two others were installed at Camp I and Tote Brook on great Rattling Brook to ascertain the salmon run to excellent spawning areas made accessible to salmon by the construction of fishways at the above mentioned sites in 1959. The counting fence insttlled at Rattling Brook s !Terris Arm, in 1956 was successfully operated in 1960 for the fourth consecutive year as a device with which to capture the adult run to that stream for transfer to Great Rattling Brook. - 2 - T 54 0 Newfoundland-Labrador f Quebec ATLANTIC 1.,./ ./ 0) Anthony OCEAN (;.- 1".< ,../. f ' ) 51 0 Gulf of St. Lawrence Indian "Nur C-3 (icSalmon Brook Bishop's Falls „ez?

River levels were "very low" from August 1 - October 15 and this undoubtedly accounts for the decreased number of salmon moving upstream.

This is the third consecutive year in which a salmon count has bean conducted on Indian River fishway. Unusually law water levels daring the latter half of the season caused the fishway to be inoperative for a period of one month. RESULTS Fishwav salmon Count The fishway counting trap was operated from June 26 to October 8.

This year a similar assumption is made.

Due to a very dry summer with resultant low water levels, the fishway counting trap was ccmpleteiy moperative for approximately three weeks (Augat 23 to Ceptember 17). Coupled with this, there was sane beaver activity adversely affecting the operation of the fishway. As a comparison with the previous veer the fishway count was identical whereas the number angled was 100 less. 1 Fishway Counting Trap Record (Indian River - 1960) Week Average H2O Average 1120 Fishway count ending temp (F0) height nr s c ri ndover L f Jul 2 67 I 10 rn . ■ 9 67 1.8 43 10 ■ 16 70 1.7 87 0 C 23 66 1.4 103 m C 30 63 1.5 90 u -4 Aug 6 65 1.1 71 .-4 13 62 1.0 39 20 62 0.3 21 8 27 60 -t 7 I p 3 -if - 1 I 10 -t - I 17 56 A -- rl 2t 51 0.7 23 Oct 1 51 0.6 - t 8 19 0.6 - i 49i4 Total 519 It River too low for fishuay opera Lion.
