e. Remarks: 
No significant change in nesting pairs of ducks. Increase in 
Canada geese. Water levels on lakes and reservoirs were 
higher this year resulting in increased production. In 1949 
many young ducks failed to reach maturity due to drying up 
of ponds. 
6. Tule Lake and Lower Klamath Refuges (Klamath Basin) 
a. Area - 35,000 acres of water and marsh with surrounding 
cultivated grain lands. 
b. Type - Great Basin. Natural and managed marsh area. 
c. Coverage - Ground observation (1949 and 1950)
