Out of Bartlett, Saguaro, Pleasant, Roosevelt, Apache and Canyon:
The family favorite is BARTLETT.
Bartlett - only issue is when water level is low, only the main (jojoba) ramp is open which can get crowded. - Nice coves for anchoring or floating and just hanging out
.
Canyon gets small rather quickly. It is a pretty cruise up the canyon though.
Saguaro is tough to get on the water unless you are there before 1100 or after 1800 - there is the sand bar up the river if its not over crowded.
Pleasant - Gets really crowded - the only lake in the west valley unless you travel 2.5/3 hours to parker or havasu - it also has some good coves and hanging out areas.
Roosevelt - its a good drive to get there, not all that pretty, not many coves to hang in.
Apache - Trip is not for the faint at heart. Winding dirt single lane road - difficult when another vehicle is approaching from opposite direction. The is basically a river - 17 miles long; however there are several good coves to hang out in.
Now there is also PARKER - HAVASU - MOHAVE - and a nice place on the Colorado River heading towards Vegas on 94 (WILLOW BEACH).
Hope this helps out all the AZ folks on here. (Yes my family has been to all of them) we did not get the boat for it sit and collect dust/dirt.
Enjoy the AZ Waters - always have PLENTY of SUN SCREEN on board.
