Report on the lake and stream openings at Bucks Lake, Plumas County, Cali- 

 fornia, 1950. Submitted January 12, 1951. 9 p. 



Abstract: An investigation was made to aid in settling a controversy as to 

 whether or not Bucks Lake should be made another exception, like Lake Almanor and 

 Butt Lake in Plumas County, and open at the same time as southern and valley 

 counties, or whether it should open at the same time as the rest of Plumas County. 

 The lake was visited on the two opening dates and a comparison made of road con- 

 ditions ; fisherman use by locals, summer home owners, resort patrons, and campers ; 

 fishing conditions ; fishing pressure ; and the biological effects on the fish.
