Alamo Lake State Park: Arizona's Best Bass Lake, a Huge Campground and the Darkest Skies of Any State Park, 37 Miles From Anywhere

A big Army Corps flood-control reservoir on the Bill Williams River in the empty country between Wickenburg and the Colorado, run as a state park since 1969. It is known nationally for largemouth bass and crappie, for wild burros wandering the campgrounds, and for a night sky with the nearest city lights 40 miles off. Seven campgrounds offer everything from dry sites to full hookups, plus four cabins, two ramps and a store. It is nearly three hours from Scottsdale, and the last 37 miles are a paved road to nowhere else.

The 30-second version

  • Alamo Lake State Park sits at about 1,200 feet on a Bill Williams River reservoir built by the Army Corps of Engineers; the park opened in November 1969 and the dam was authorized by the Flood Control Act of 1944.
  • Camping ranges from $25 dry sites to $40 water-and-electric and $50 full-hookup sites across campgrounds A through F and Cholla, with restrooms in every loop, showers in A, C and the main campground, two dump stations and two paved boat ramps; there is no limit on RV length at the 19 full-hookup sites.
  • Four air-conditioned camping cabins with four bunks, a porch and electricity rent for $85 per night plus a $5 reservation fee; bring your own linens.
  • Entrance is $10 per vehicle with one person, $20 for two to four people and $5 per bicycle, on top of camping; second vehicles pay $15 per night.
  • The drive from Old Town is about 2 hours 50 minutes: Loop 101 to US 60 through Wickenburg to Wenden, then 37 miles north on paved Alamo Road. Fuel and propane are in Salome, not at the lake.
  • The lake is considered one of the country's best bass and crappie fisheries, with the hot season February through July; an Arizona license is required at age 10 and up, and the Low Water boat ramp is closed when the lake is down.

What is Alamo Lake State Park?

Alamo Lake is what happens when the Army Corps of Engineers dams a desert river for flood control and then has to do something with the water. The Flood Control Act of 1944 authorized the dam on the Bill Williams River to protect the lower Colorado; the Corps finished it in 1968 along with a campground, a ramp and a paved road from Wenden, and Arizona State Parks took over the shore in November 1969 while Game and Fish took the water. The lake’s size swings with runoff, which is part of why the fishing is so good: flooded brush, shallow structure, and bass and crappie that draw anglers from across the country.

The park sits at about 1,200 feet in bare, rocky Sonoran Desert, 4,900 acres of shore 37 miles from the nearest pavement that goes anywhere else. That isolation is the other attraction. The nearest city lights are 40 miles away, the sky is as dark as any developed campground in Arizona, and the park runs star parties through the winter. Wild burros, descendants of prospectors’ animals, graze through the campgrounds at night. Bald and golden eagles winter here. The camping is extensive: Campground A with basic sites, B with 42 mixed sites, C with 40 water-and-electric sites, F with 15 full hookups, the main campground with 19 full-hookup sites and no RV length limit, Cholla with 41 electric sites and its own ramp, and D and E for dry camping. Restrooms are in every loop, showers in A, C and the main campground, dump stations at Cholla and the main campground. Four air-conditioned cabins with bunks and porches overlook the lake.

What you get is hookups, hot showers and a store in a place with no town, no traffic and no light. What you do not get is groceries, reliable cell service, a beach, or a boat ramp you can count on in a dry year.

How to camp Alamo Lake right

Book, and pick the loop for your rig. Entrance $10 per vehicle with one person, $20 with two to four, $5 per bicycle. Camping $25 dry or non-electric, $40 water and electric, $50 full hookup, plus a $3.60 reservation fee; cabins $85 plus $5, up to 365 days ahead. Second vehicles pay $15 a night. Check-in is 2 p.m. for sites and 3 p.m. for cabins. C or the main campground for showers and power; D and E for tents and the OHV crowd, where the park asks riders to camp.

Get there, and fuel up in Salome. About 2 hours 50 minutes from Old Town. Take Loop 101 west to US 60 (Grand Avenue) and follow it northwest through Wickenburg, then west through Aguila and Salome to Wenden. Turn north on Alamo Road and drive 37 miles of paved two-lane across open desert to the park entrance. Salome has the last fuel and propane. The road is fine for any vehicle and trailer; watch for cattle and burros. The Hassayampa River Preserve at Wickenburg is the stop on the way.

Pick the season. Year-round, but October through April is the camping season and February through July the fishing season. Summer highs exceed 110 degrees, and only the cabins and hookup sites make sense. The Low Water ramp closes when the lake drops; check the park page before you tow.

Water and supplies. Potable water, flush restrooms and showers in the park. The store sells ice, bait, firewood and snacks, not groceries. Bring everything else, including more ice than you think.

Fish the brush. Largemouth, crappie, redear, catfish, bluegill and tilapia; Arizona license at 10 and older; the store sells minnows October through May. The flooded brush along the shore is where the fish are, which is why the lake’s level matters more than the weather.

Stay up. The Alamo Lake Star Party in November and the monthly dark-sky nights are the easiest way to look through a serious telescope in Arizona; see the stargazing note for the moon calendar. Even without a scope, the horizon here has no glow.

Burros, OHVs, dogs. Burros wander through camp at night; keep food in the vehicle and do not feed them. The surrounding BLM roads are an off-highway playground, so expect engine noise in C, D and E on winter weekends. Dogs on leash; two per cabin, declared at booking.

Skip it if three hours and no town is too much. Lake Pleasant has hookups an hour from Scottsdale; Burro Creek on US 93 is the BLM alternative with a creek and no lake.

A town at the bottom of a flood-control lake

The Bill Williams is a desert river, mostly dry and occasionally enormous, draining the Big Sandy and Santa Maria rivers out of the Yavapai uplands and running west through a gap in the mountains to the Colorado. Its valley is the old seam between the Yavapai to the east and the Mohave and other river peoples along the Colorado, and its name comes from Bill Williams, the mountain man who trapped it in the 1830s. For most of the nineteenth century the only reason to be here was ore. In the late 1890s Tom Rodgers founded Alamo Crossing at the best ford on the river as a base for prospectors working the Artillery Mountains. It never amounted to much: a five-stamp mill, a few stores, a post office that opened in 1899 and closed for good in 1918, and residents who mostly camped rather than lived. A manganese boom in the early 1950s brought it back for a few years, with the Mesa Manganese and neighbouring mines working until about 1954; the 1960 census counted 18 people at the crossing.

The river’s floods were the problem, and not for the people at the crossing. When the Bill Williams ran big it dumped into the Colorado just above Parker Dam, and the federal government had just spent two decades building dams and canals along that river. Congress authorized the Alamo Dam in the Flood Control Act of 1944, on the Chief of Engineers’ recommendation, to keep Bill Williams floods off the lower Colorado and, secondarily, to store water and provide recreation. The Army Corps of Engineers built it through the 1960s and finished it in 1968: an earthfill dam rising 283 feet from the streambed, with a reservoir that in a wet year reaches back 15 miles. The water covered Alamo Crossing, in places 80 feet deep, and the old town road still runs down into the lake. The Corps built a campground, picnic area, beach, restrooms, a boat ramp and a paved road 38 miles north from Wenden, and then looked for someone to run them.

Arizona State Parks had been looking at Corps reservoirs since its ten-year plan of 1958. Talks began in early 1963, with a joint inspection in October, and in April 1969 the Parks Board signed a management agreement with the Game and Fish Commission and a 25-year lease with the Corps: the state would run the shoreline facilities and Game and Fish the lake surface, a split that still holds. Alamo Lake State Park was dedicated in November 1969 with Wayne Perault as its first manager. It was, and is, the most remote unit in the system.

The fishing was an accident of hydrology. Unusually high flows in the 1970s and 1980s filled the lake far beyond what the Corps had expected, flooding the mesquite and palo verde along the old valley floor and giving largemouth bass and crappie the brushy structure they thrive in; the lake has been known to rise 11 feet in a night. Game and Fish stocked and managed it, the bass tournaments came, and the park grew from the Corps’ single campground into seven loops, hookups, two ramps, a store and four cabins. The state signed a new 25-year lease on September 1, 1997. The burros, descended from the prospectors’ animals, were here before any of it and have never left. The lake’s level still swings with the runoff, which is why the Low Water ramp has a name, and why the brush that makes the fishing is sometimes a hundred yards from the water.

Why it matters

Alamo explains a kind of Arizona lake that Scottsdale visitors rarely see: not a Salt River Project reservoir built for irrigation, but an Army Corps flood-control dam whose water is a by-product, run by a state park on a federal lease with a town at the bottom. It also explains why the bass are so good, which is runoff, not management. For a visitor the verdict is clear: it is too far for a night and exactly right for three, with hookups and hot showers in the darkest, quietest campground the state operates. Fill the tank in Salome, book C or the main loop, bring your own ice, and stay up late.

How it got here: a timeline

  1. prehistory

    The Bill Williams valley is the seam between the Yavapai, who hold the uplands to the east, and the Mohave and other river Yuman peoples along the Colorado; the river itself is named later for Bill Williams, the mountain man who trapped it in the 1830s.

  2. late 1890s

    Tom Rodgers founds Alamo Crossing at the best ford on the Bill Williams as a base for prospectors working the Artillery Mountains; it gets a five-stamp mill, a few stores and a post office that opens in 1899 and closes for good in 1918.

  3. 1944

    Congress authorizes the Alamo Dam in the Flood Control Act of 1944, on the Army's recommendation, to keep Bill Williams floods off the lower Colorado and its new dams.

  4. early 1950s

    A manganese boom briefly revives Alamo Crossing; the Mesa Manganese and neighbouring mines run until about 1954, and the 1960 census finds 18 people still living at the crossing.

  5. 1968

    The Army Corps of Engineers completes Alamo Dam, an earthfill wall 283 feet above the streambed, and the rising lake covers Alamo Crossing, in places 80 feet deep; the Corps builds a campground, beach, ramp and a paved road from Wenden.

  6. 1969

    The Parks Board signs a management agreement with Game and Fish in April and a 25-year lease with the Corps, and Alamo Lake State Park is dedicated in November with Wayne Perault as its first manager; the state runs the shore and Game and Fish the water.

  7. 1970s–1990s

    Unusually high flows in the 1970s and 1980s fill the lake far beyond expectations and flood the brush that makes the bass fishing; the park adds loops, hookups and cabins, and in September 1997 signs a new 25-year lease.

  8. today

    Seven campgrounds, four cabins, two ramps, a store, burros in the loops and the darkest sky in the state park system.

Questions people actually ask

How much does it cost to camp at Alamo Lake?

Dry and non-electric sites are $25 per night, water-and-electric sites $40, and full-hookup sites $50, each plus a $3.60 reservation fee. The park entrance fee is charged on top for every vehicle: $10 with one person, $20 with two to four. Second vehicles at a site pay $15 per night. Cabins are $85 plus $5.

Which campground should I pick?

Campground A (17 to 21 basic sites) and B (42 mixed sites, 27 with electric) are near the visitor center; C has 40 water-and-electric sites and a shower house; F has 15 full hookups; the main campground has 19 full-hookup sites with no RV length limit; Cholla has 41 electric sites and its own ramp and dump station; D and E are dry camping with tables and fire rings. Showers are in A, C and the main campground.

Is there food, fuel or cell service at Alamo Lake?

The park store sells ice, bait, firewood, drinks and snacks, but no real groceries. The nearest fuel and propane are in Salome, about 45 minutes away. Cell service is spotty and depends on carrier. Bring everything.

What is the fishing like?

Alamo is regarded as one of the premier largemouth bass and crappie lakes in the country, with redear, channel catfish, bluegill and tilapia too. The park says the hot season is February through July. An Arizona fishing license is required for anglers 10 and older, and the store sells minnows October through May.

Can I swim?

Yes, at your own risk; there are no beaches and no lifeguard. Most people fish, paddle and boat instead. Both ramps are paved; non-motorized boats can launch from either.

Are dogs allowed?

Yes, on leash, in campgrounds and on trails. Cabins allow up to two declared pets for a $10 charge per cabin.
