Lake Pleasant Is at Its Low Point. Here's How the Park Changes as It Refills This Winter

Lake Pleasant is about half full right now. On October 14, 2026, the Central Arizona Project's live operations reading put the water surface at 1,652.64 feet, 50.18 percent of maximum storage, measured against a full-pool elevation of 1,702 feet. That leaves the lake roughly 49 feet below full, with about 6,700 acres of water surface. Maricopa County's park page says the surface can range from just over 3,000 acres to almost 10,000 acres when the lake is full.

That number explains most of what changes at the park over the next five months. The cool season, when the trails are worth hiking at midday, is also when the reservoir refills. The park you drive into from Peoria the weekend after Halloween will look different by mid-March: more water, less shoreline, one fewer trailhead, and part of the lake closed to boats.

The water is about to start rising

Lake Pleasant isn't a natural lake that slowly drains. It's CAP's storage reservoir, and CAP describes the yearly cycle plainly. It pumps Colorado River water into the lake during the fall and winter, then releases it in spring and summer when demand goes up. The county's park page describes the same pattern from the shoreline. The water usually peaks in March and April and bottoms out in October and November.

So late October sits at the bottom of the curve. CAP said earlier this year that even with the Tier 1 Colorado River shortage declared for 2026, it expected the lake to drop this year but stay within normal historical operating ranges. CAP also says there is a lot of uncertainty about lake levels after 2026.

The low water shows up first in parking. The county's park-updates page says lower shoreline levels currently provide additional parking, and that less parking will be available as the water rises. With CAP pumping through the winter, the extra shoreline parking available in early November is the most there will be all season. The county also warns that it may temporarily close parts of the park when parking lots and shoreline exceed capacity or when high water limits shoreline. A main-entrance closure means no new entries or re-entries until after 4 p.m. that day.

The Pipeline Trailhead closes November 10

The biggest change for hikers isn't caused by the water. From November 10, 2026, through March 10, 2027, Maricopa County Parks and Recreation will close the Pipeline Trailhead, its parking lot and restrooms, and portions of the Pipeline Trail near North Park Road and Peninsula Boulevard. Road closures, signs and barricades will block access during construction.

The county calls the work the ET Bed Rehabilitation Project. In the parks department's January 2026 capital-project report, redesign of the "Lake Pleasant Pipeline South ET bed" appears as an infrastructure improvement that will go to an outside contractor.

The closure covers almost exactly the stretch when the lake is rising and the weather favors daytime hiking. It ends on March 10, just as the water approaches its usual spring high.

The county's closure alert names two alternate access points, the Cottonwood Day Use Area and the Wild Burro Day Use Area. Both connect to trails outside the work zone. The county's park-updates page says hikers can use the Cottonwood Day-Use Area through the North Entrance. The hiking page puts the Roadrunner Trail entrance at the northeast corner of the Discovery Center parking lot. Here is how the alternatives compare, using the trail lengths on the county's trail list:

Roadrunner is the easiest option for families. The county's hiking page says it links the Discovery Center to Picnic Areas A and B and the 10-Lane Boat Ramp. The county's own pages list two different lengths for it, so check the trail map before you set a distance goal. The Discovery Center itself is open Friday through Sunday, 10 a.m. to 4 p.m.

Cottonwood comes with a catch for anyone who likes to end a hike at the water. The county allows hikers at the Cottonwood Day-Use Area, but it lists no shoreline access at Cottonwood Cove until further notice. At the North Entrance, shoreline day use is limited to Fireman's Cove.

The county's park-updates page currently lists these trailheads as accessible: Agua Fria, Beardsley, Brown, Cottonwood Day-Use Area, Frog Tanks, Pipeline Canyon Day-Use Area, Roadrunner, and Wild Burro. That list was posted before the November closure starts. Expect the Pipeline area to change once barricades go up, and follow posted signs.

A winter calendar set by the reservoir

The Pipeline closure is one of several changes spread across the season. Most of them follow the water. In order:

1. November 1. Main entrance hours switch from 5 a.m.–9 p.m. to 6 a.m.–8 p.m. daily, through April 30. The North Entrance Station follows the same schedule, and all visitors must leave when the park closes.
2. November 10. The Pipeline Trailhead, its lot and restrooms, and nearby trail sections close.
3. December 15. The Agua Fria River arm of the lake closes for the annual bald eagle nesting season, which runs through June 15. Buoys mark the closure area to keep boaters out.
4. January through March. The county expects the middle parking lot at the Agua Fria Conservation Area to be available. The upper lot is open year-round.
5. Late February through March or April. The county projects that the Agua Fria boat launch parking area will open, and it posts updates on its Agua Fria fishing schedule page.
6. March 10. The Pipeline Trailhead closure is scheduled to end.

The earlier closing time matters most to anglers. Once the main entrance closes, everyone without a camping reservation has to leave the park. The county lists three ways to fish after 8 p.m.: a park campground reservation, a boat-in angler camping reservation, or Pleasant Harbor Marina. Night anglers can stay out as long as their boat stays in open water. Once a boat is beached, the county's park-updates page says it counts as shoreline camping, which isn't allowed and can lead to a citation. Shoreline camping stays closed. The Dirt Spillway Primitive Camp Area is open, reached only by Sunset Ridge Road.

Pleasant Harbor runs on its own schedule. The county notes that closures at Lake Pleasant Regional Park don't affect Pleasant Harbor Marina on the east side of the lake. For boat launching on the north side, the county lists the Castle Creek/4-Lane Boat Ramp as the open ramp. Scorpion Bay Marina visitors are asked to contact the marina directly about how park changes affect their visit.

Until November 1, it's still the summer park in cooler weather

Through October 31, the park still keeps its long summer hours, the lake is near its low, and the Pipeline Trailhead is open. A few scheduled events fall inside that window.

The Maricopa County Parks events calendar lists an Introduction to Archery session on October 24, 2026, the Lake Pleasant Monday Clean-Up Crew on October 26, and Creatures of the Night on October 28. Scorpion Bay Marina's events calendar lists Sunset Cruises on October 24 and October 31, booked through the marina, but the calendar doesn't show a year. Confirm dates and times with the marina before you go.

The county hasn't yet posted its November through March program calendar for the park. When it does, those events will take place in a park that has fewer access points and more water than it has today.
