PRIVATE BOAT FISHEHI 



This unit of the Yellowstone Lake fishery is the most difficult upon 

 which to gather accurate creel census data. It is not feasible to attempt 

 to interview anglers in private boats as they lack any semblance of an 

 orderly fishing pattern. Many of the boats of the larger inboard type do 

 not return to the docks until late at night and sometimes will spend 

 several days in the South or Southeast Arm with the passengers sleeping 

 aboard. As previously noted, the smaller boats on trailers are launched 

 at any number of locations along the shoreline, and, they too, often do 

 not land until late in the evening. Because of the nature of this unit 

 of the fishery, any estimates of total catch would necessarily be based 

 on assiJmptions for want of more accurate data.
