In July, 1890, the water temperature rose to a maximum of 72° F, in 
rearing troughs fed from Craig Brook. In conduits supplied in part by 
spring water the temperature was 69°, and after passing through four 
rearing troughs in succession it was 72°. In August the water in the 
hatchery was 58° to 76°; in open-air troughs, 59° to 75°; and in the 
ponds 58° to 744°. Experimental lots of salmon fry were kept in two 
neighboring streams, and in one of them, at East Orland Bridge, the 
water rose August 4 to 82° without injuring them. The September 
temperature was 69° to 53°; October, 63° to 46°; November, as low as 
37°, from 24th to 29th; January, 32$° to 35°, with nearly all the fish 
remaining in the open-air troughs; February, 324° to 36°, with weather 
comparatively mild and the ice on Alamoosook Lake 294 inches thick.
