is better than all of the other lakes in TCL. Relative numbers of brook trout are down from a 

 1983 inventory (6.0 per net and 1.0 per net for 1983 and 1992, respectively). This is probably 

 due to increased predation (on fry) and competition (with adults) with the introduced yellow 

 perch. 



Although not covered in this fishery management plan, the need for legal access and the poor 

 condition of the road are frequently mentioned concerns. 



Management Concerns; 



Yellow perch introduced to lakes in northwest Montana have shown tendencies to produce stunted 

 populations after an initial boom of large perch. When this happens, naturally reproduced fry 

 (like brook trout) and planted fry (rainbow trout and cutthroat trout) are highly suscq)tible to 

 predation. In addition, the high densities of yellow perch that compete for food and space may 

 reduce both growth and survival of the game fish. Stocking becomes less successful and 

 hatcheries must produce a larger (and more expensive) trout to maintain survival, 



Prftfprred Management Option; 



Managemoit opticms considoied included current management and trout stocking, chemical rehab 

 and restock with trout, adjust trout stocking rates, manage for yellow perch, and add a predator 

 such as pike to control perch. There were 57 comments on Little McGregor Lake. 



Under the preferred management option, Little McGregor Lake would be managed as a brook 

 trout/rainbow trout/ydlow perch fishoy. Through monitoring and ad^tive management, stocking 

 rates and sizes of rainbow trout and brook trout will be altered to produce a satisfactory fishery 

 and to shift emphasis back to brook trout. The lake would be rehabbed and returned to a trout 

 fishery if the yellow perch overwhelm the fishery.
