 the vicinity of Iledding on the north to 



Carq 



It Ib a 



broad, flat plain 160 miles long, 50 milea 

 "wride at the south, and tapering gradually 

 to about 20 miles in "v^idth near Redding. 

 The valley is 557 feet above the sea at 

 Iledding and slopes down to sea level at 

 Suisun Bay. 



The ax-ea of the valley is about 6,500 

 square miles, of which 2,633,000 acres, 

 nearly two-thiixls— is bottom land. On 

 the east side of Sacramento Hiver 535,000 

 acres and on the west side 424,500 acres, 

 or 959,000 acres in all, is now subject to 

 occassional overflow. Of this land more 

 than 300,000 acres is protected bv dikp« 



The total irrigable area, including the 

 rolling land Ijing north of Red Bluff, is 

 2,500,000 acres, of which 123,500 acres was 

 irrigated in 1912. 



The principal tributaries of the Sacra- 

 mento are Feather, American, and Moke- 

 lumne rivers, which rise in the Sierra 

 Nevada. In the flatter parts of the valley 

 overflow at some point is a yearly occur- 

 rence. The overflowed lands, which in 

 many places support a luxuriant swamp 

 vegetation, are among the most fertile in 

 the valley, and levees have been built to 

 reclaim them. 



For five months, October to March, the 

 weather is cool and rainy, but the rest of 

 the year is practically rainless. Summer 

 temperatures are high, reaching US'" F.,
