REPORT OF COMMISSIONER OF FISH AND FISHERIES. 83 
of 1891. Other specimens sent consisted of 9 wild adult brook trout, 
4 wild adult salmon, and a small collection of smelt from Green Lake. 
The only fish liberated, and these by accident, consisted of 500 of the 
| younger salmon, which escaped into Green Lake November 16 through 
‘the misplacement of a screen. On December 14 there were 19 small 
German carp sent to the station by Dr. W. M. Haines, of Ellsworth, 
and liberated in Great Brook, tributary to Green Lake. 
Landlocked salmon.—The salmon of Green Lake, averaging 6 pounds 
in weight, ordinarily spawn in the inflowing streams, but some pass 
‘through the outlet and lay their eggs below in the waters of Reed 
‘Branch, as was this year definitely proved. When the spawning period 
arrives during the seasons of drought, the affluents being low, the fish 
‘will not pass up, but remain in the lake. To induce them to ascend 
Great Brook at such times it is necessary to resort to artificial flushing, 
‘and there being facilities on the headwaters for accomplishing this, 
‘success has been attained. Mountainy, the uppermost pond, 5 miles 
‘distant, is used as the flushing reservoir, the system pursued consisting 
in opening gates about 2 p. m., creating a large flow throughout the night. 
‘The rainfall in September and October having been slight, there was by 
‘November 1 barely sufficient water for this purpose and the station 
proper. Great Brook was the only affluent affording adult fish, though 
in October many were seen jumping near the mouths of other inlets. 
Egg collections being wholly dependent on wild fish, arrangements 
for capture were effected in September, at which time the slat traps 
iin Great Brook were repaired, another obstruction being put in position 
‘at the discharge of Mann Brook. Two others were located at the lower 
end of the lake, one just inside, for the capture of outward-moving fish, 
and the other in Reed Brook, about a mile below, for the capture of fish 
ascending. Wire screens were, in November, placed in the gateways at 
the discharge of the lake to prevent fish escaping. Before the screens 
‘were inserted aS many as 100 young salmon from 6 to 10 inches long 
ywere at one time seen below the dam. 
The aggregate catch was 152, Great Brook furnishing 83 and the lake 
outlet trap 69. Of the captures at Great Brook trap, 53 were females; 
of those from the outlet of the lake, the females numbered 26. One 
salmon bearing “No. 2” tag, attached in 1890, was taken. The first 
capture,on September 27, consisted of two males and three females. 
“On October 31 the first eggs of the season, 12,000 in number, were 
‘obtained. The largest success at the outlet of the lake was November 
4, when 14 fish were taken, 8 of the 9 females affording 22,000 eggs of 
good quality. The most successful day was November 9, when 31,500 
eggs were taken from fish held in the Great Brook traps. The last eggs 
were taken November 23, and the next day all parent fish were set free 
in the lake, the total of eggs for the season being 213,300. Aninspection 
of the stream feeding Mountainy Pond was made in October, and also 
that connecting Mountainy and Rocky ponds in November, to determine 
the presence of available spawners, but no indications were found.
