South West Arizona Region
Martinez is a great place to fish, it's part of the Colorado River so you have to pay attention to the rise and fall of the river. Summertime is petty brutal but fall and winter the temps are a little warmer than Phoenix.
Despite its remote location, Alamo Lake State Park receives relatively large numbers of visitors in the mild seasons of spring, winter and fall, mostly because of the good fishing it offers - bass and catfish are especially plentiful. The reservoir was formed in 1968 by the construction of Alamo Dam for flood control purposes on the Bill Williams River, and is now the fifth largest in Arizona, though as with all Southwest lakes, the surface area varies a lot from year to year.
