SALMON INVESTIGATIONS IN IDAHO IN 1895. 
16 !) 
The outlet is quite steep for some distauce, ami fish can not ascend to the lake. 
The temiierature of the lake at the surface was 50° at iiooii, September 10, when the 
air was 3<S°. 
The following is a list of temperatures taken from the shore of Big Payette Lake 
about a mile east of the outlet. The lake at this point is shallow for i)robably 150 feet 
out from shore, where the bottom breaks off i3reeii)itously. Near the shore there is a 
scanty growth of various sorts of water vegetation. The water probably varies more 
in temperature at this point than it does at the surface in the deep portion of the lake.
