The region covered by Map 2 has the largest stream mileage 

 but this is also the largest area. The greatest mileage in propor- 

 tion to area is found on Map 1. This is in the upper East Branch 

 of Fish creek which also has a much higher altitude (1,600-1,900 

 ft.) than any other region. Here also the brook trout stream mile- 

 age and area are much greater than for browns (135 to 27 miles). 

 AVe likewise find here less pollution, more timber, fewer dry 

 streams, fewer people, fewer roads, a greater advantage for natural 

 spawning and a much denser population of brook trout. The 

 region stands out above others in the quality of its trout streams. 



The combined areas represented by Maps 3A and 4A have fewer 

 trout streams than any one of the others except Map 7 which is 

 too small for comparison. There is a total of 66 miles of which 

 25.2 are suitable for brook trout, 43 for browns and 8.4 for rain- 

 bows. Map 3A includes principally that region lying along the 

 route of the barge canal from Cross lake to a place just beyond the 

 Wayne-Monroe county boundary. It covers much of the low lying 

 country in the Montezuma marshes and along the Ganargua creek 

 and lower Clyde river. None of the streams is above the 600 foot 

 contour. They are mostly brown water, often turbid, fairly slug- 

 gish, badly exposed, in a densely populated section which is in 

 general the Avarmest part of the area covered. Here Ave find but 

 29.5 miles of trout stream in comparison with 38.7 for Map 4A. 

 The ratio of brook trout to broAvn trout streams is hoAvever loAvest 

 in Map 4A (5.2 to 33.5). The feAv trout streams in these two sec- 

 tions are Avidely scattered and often are formed by one or more 

 conspicuous springs. North brook near Auburn made suitable for 

 trout solely through the influence of the Price spring is a note- 

 Avorthy example. Tt receives pollution. As one goes to higher
