Report on the Emerald Valley stream, dated 12th February 1907. 

 Temperature, upper reaches — Noon, bright sun, 56 Fahr. 



3 P.m. „ 58° 



,, lower reaches — II a.m. ,, 6l° ,, 



This stream rises in the hills opposite Avalanche and flows over 

 a rocky and precipitous bed to the foot of the hills. From here 

 downwards the nature of the bottom is gravel and sand and in the 

 higher waters there is a fair amount of useful shade. There are 

 good pools and the stream is very accessible for fishing. 



I examined it thoroughly, but found no trace of trout, which 

 were put in some years ago. The few that remained must have 

 moved into the lower deep pools or have been poached. There was 

 no evidence of any fish having been in the upper waters for spawn- 

 ing purposes. I examined the gravel beds in the upper waters 

 where fry would most likely be, but found none. 



The stream contains indigenous minnow, mollusca and small 

 animalcules, a fair amount of shade in the high reaches, suitable 

 spawning grounds with good temperature and very clear water. 



I consider it should make a good stream for trout and, if care- 

 fully watched after stocking, they ought to breed in the upper 

 waters as the temperature and nature of bottom are all that can be 

 desired. 



This stream joins the Avalanche river.
