What is Bartlett Lake?
Bartlett is the reservoir that catches the Verde River before it reaches the Valley, backed up behind a concrete dam the Bureau of Reclamation finished in 1939. Full, it covers about 2,815 acres, two and a half times Saguaro Lake, in a long blue arm between bare brown mountains at 1,798 feet. Unlike the Salt River lakes, it has no highway along it and no town; what it has is a single paved road from Carefree that ends at a cluster of Forest Service sites along the west shore, and that is the whole point. It is the big lake you can reach from north Scottsdale in about an hour without touching dirt.
Those sites are the lake, for a visitor. Rattlesnake Cove is the day-use center: 41 ramadas with tables and grills, vault toilets, stairs down to a gently sloping swimming beach, and a cove closed to motorboats. Yellow Cliffs and Jojoba are the motorized launches. The Bartlett Lake Marina rents pontoons, fishing boats, jet skis and paddleboards and has the only flush toilets and drinking water on the lake. North of all that, FR 459 runs to SB Cove and Bartlett Flat, the shoreline camping areas, where there are no designated sites and you simply drive onto the sand and stop. The Palo Verde Trail links Rattlesnake Cove to Bartlett Flat along the bluffs.
What you get is a desert reservoir with the shade and the crowding that implies, and a water level that decides each year whether your camping beach exists. What you do not get is a resort, a store, a hookup or a line of RVs along a highway. For the lake’s place in the Valley’s plumbing, see the lexicon entry that pairs it with Saguaro.
How to do Bartlett right
Check the level before you choose a shore. SRP publishes the reservoir levels daily. At high water SB Cove has almost no beach and the campers crowd onto Bartlett Flat; at low water both become wide sandy flats where you can pull a truck or a small trailer nearly to the edge, which is the best cheap camping within an hour of Scottsdale. The launch ramps work the other way: full lake, short walk; drawn down, a long concrete slope and a line of trailers at the bottom.
Buy the pass in town. Every vehicle needs a Tonto Pass: $8 from a vendor in Carefree or at the Cave Creek Ranger Station, $12 at the fee machines, which are far apart (Desert Vista overlook, the Jojoba launch). Motorboats add a $4 watercraft sticker. The $80 annual Discovery Pass covers both and pays for itself in ten visits. America the Beautiful passes work only at the picnic sites, not for camping or launching.
Get there. Take Scottsdale Road or Pima north to Carefree, then Cave Creek Road about 7 miles to Bartlett Dam Road (FR 19) and turn right. It is 13 miles of paved, winding two-lane over the ridges; at the stop sign at the bottom, left is the north-shore sites, right is the marina and the dam. Figure 65 minutes from Old Town. For SB Cove and Bartlett Flat, turn left on FR 459 before the marina: 3 miles of slow pavement, then a half mile of dirt to the Flat.
Pick your season by your boat. October through April is camping and paddling weather, and a winter weekday can hand you a cove to yourself. Summer is wake-boat season: the ramps queue by mid-morning on weekends, Rattlesnake Cove’s lots fill, and the afternoon wind builds most days. Paddlers should launch early, stay in the no-wake coves and be off the water by noon.
Camp by the rules. Shoreline camping is SB Cove and Bartlett Flat only, 14-day limit, no sites, no hookups, vault toilets, quiet hours 10 p.m. to 6 a.m., no glass. There is no drinking water at any Forest Service site; the marina tap is the only one on the lake and keeps business hours. Dogs are fine on leash at the sites and beaches. Fire restrictions arrive most years by May; check before you count on a campfire.
Swim at Rattlesnake, fish anywhere. Rattlesnake Cove is the designated beach, gentle and motorboat-free, and the place to take kids. Bartlett is a bass and catfish lake with a long record of big smallmouth, and the Fish City habitat project off Bartlett Flat holds fish in winter. The cove’s fishing dock is closed while a replacement is built; shore fishing is open everywhere.
Skip it if you want moving water or shade. Needle Rock and Box Bar on the free-flowing Verde are 20 minutes closer, and Horseshoe Campground below the upper dam has actual cottonwoods. For a lake day that is also a trail day, Butcher Jones on Saguaro Lake has the better walk.
The dam that made north Scottsdale possible
The Salt River got its dam first. Roosevelt went up in 1911, and for the next quarter century the Salt River Valley Water Users’ Association ran its whole system on the Salt while the Verde, the Salt’s biggest tributary, came and went as it pleased, flooding the lower valley in wet winters and vanishing in dry ones. The Association wanted a Verde dam from the start; it took the Depression and the Bureau of Reclamation’s public-works money to get one.
Reclamation built Bartlett Dam between 1936 and 1939, 20 miles above the Verde’s mouth. It was an unusual structure for its day: a multiple-arch dam, ten concrete arches leaning upstream against buttresses, nearly 300 feet high, the tallest of its type in the United States when it was finished and still one of the few in the West. It was named for Bill Bartlett, a government surveyor who had worked the Verde a generation earlier. The reservoir it made holds about 178,000 acre-feet, a modest figure beside Roosevelt’s 1.6 million, but the first storage of any kind on the Verde and the reason the Valley’s farms stopped flooding in February.
The second Verde dam followed a strange route. During the Second World War, Phelps Dodge needed water for its copper towns at Morenci and Clifton, on the far side of the state. Rather than build its own reservoir, the company paid for Horseshoe Dam, finished in 1946 fourteen miles upstream of Bartlett, in exchange for the right to divert an equal amount of water from the Black River on the Salt’s headwaters. The Valley got a second reservoir for free; Phelps Dodge got its mine water; and the Verde became what it is today, two lakes in series with Horseshoe drawn down first each year so that Bartlett, the lake people actually visit, stays fuller longer.
Recreation came last and slowly. Through the 1960s and 1970s Bartlett was a fishing lake at the end of a bad dirt road, and the shoreline camps were whatever flat spot you could reach. The paving of Bartlett Dam Road, the marina concession and the built-out fee sites at Rattlesnake Cove, Jojoba and Yellow Cliffs all date from the 1990s, the same decade Scottsdale’s growth reached Carefree Highway and the lake became, for the first time, an hour from a large population. The Tonto Pass arrived in 1999 to pay for the toilets and ramadas that the new crowds required.
The lake’s next chapter is already being drawn. Horseshoe has silted badly and its dam is old; SRP and Reclamation have spent the 2020s studying a plan to raise Bartlett Dam by roughly 100 feet, which would more than double the reservoir and let Horseshoe be retired or run nearly empty. If it happens, every site in this guide, the road included, ends up under water and gets rebuilt higher on the slope. It would be the biggest change to a Valley reservoir since Roosevelt was raised in 1996.
Why it matters
Bartlett is the lake that explains the rest of them. It is the Verde’s answer to the Salt’s chain of lakes, built later, built differently, and run on a water-credit swap with a copper company that nobody outside SRP remembers. For a visitor it is simpler than that: the one big lake you can drive to from north Scottsdale on pavement, where the camping is free with the pass and the beach is as wide as the drought makes it. Watch the level, buy the pass in town, and it is the easiest overnight within an hour of Old Town.
