When does Lake Pleasant hold the least water all year? For most of north Peoria the honest guess would be late summer, after months of triple-digit heat. Maricopa County Parks puts the low point in October and November, and the high point in March and April.
The lake runs on a calendar that doesn't follow the weather. The summer weekends packed with boats are the stretch when the water is going down. The cool months, when the lake gets quiet, are when it fills back up. That makes the next few weeks the lake's turning point, and the calendar between now and mid-December is set up around it.
Where the gauge sits this week
The Central Arizona Project posts a live reading for Lake Pleasant. Here's the snapshot from October 4, 2026, next to the reservoir's limits.
| Measure | October 4, 2026 | Reference point |
|---|---|---|
| Water surface elevation | 1,651.49 feet | 1,702 feet at maximum |
| Share of maximum | 49.2% | 100% at 1,702 feet |
| Surface area | About 6,654 acres | From over 3,000 to almost 10,000 acres across a year |
| Waddell pumping plant | Pumping about 425 cubic feet per second | Water flowing into the lake |
The last row matters most. As of this reading the Waddell plant was pumping water into the lake. The low point and the start of the refill are happening at the same time.
Why the lake fills when the Valley cools
Lake Pleasant is CAP's storage reservoir, near the middle of the canal system that carries Colorado River water into central Arizona. According to CAP, it pumps Colorado River water into the lake during fall and winter and releases it in spring and summer, when demand runs higher. The lake also catches runoff from the Agua Fria River, but the canal drives the yearly cycle.
This year comes with a caveat. A Tier 1 shortage declaration for Colorado River operations took effect January 1, 2026. CAP said it did not expect that to hit Lake Pleasant significantly in 2026. It did expect the level to drop, but to stay within normal historical operating ranges. CAP also says there is a lot of uncertainty after 2026, so it is hard to project the lake beyond this year. For anyone who uses the lake, the practical step is to check the live gauge before a trip instead of assuming last year's shoreline.
What a low lake changes at the water's edge
The lower water shows up first at the ramps. Maricopa County Parks says the 10-lane ramp and the 4-lane ramp at the north end both stay usable down to a water elevation of 1,600 feet. The October 4 reading left about 51 feet of room above that line. Even at the seasonal low, the two main ramps were well within working range.
The Agua Fria boat launch follows different rules. The county says access there depends on the water level and is usually available only at higher elevations. The shallow launch suits small fishing boats and paddlecraft. No numeric cutoff is published. For kayakers who launch there, this is the least reliable stretch of the year, and it improves as the refill continues.
On shore, the county warns that water levels vary and that parts of the Pipeline Canyon Trail can be temporarily underwater because of seasonal rain or CAP water operations. Because the shoreline keeps moving as the lake changes, the hike can look different from one month to the next.
The fall calendar, in the order it happens
The county and the marinas have posted a run of dated events that follow the lake from its low point into early winter. Most need advance planning.
- Monday Clean-Up Crew, ongoing. Lake Pleasant's shoreline litter crew meets Mondays from 7 to 9 a.m. The park lists it on October 5 and 12, and it is still on the calendar for December 7.
- October 8. Morning Meander and Discovery Station are both on the park calendar. The Discovery Center is open Friday through Sunday, 10 a.m. to 4 p.m.
- October 16. The Pipeline Canyon Fitness Hike runs 6 to 8:30 p.m. It's a moderate four-mile round trip, registration is required, and it's capped at 15 people.
- October 17, 24 and 31. Scorpion Bay's online events calendar shows sunset cruises on all three dates, 5 to 6:15 p.m. The calendar doesn't print a year, so confirm with the marina before you plan around them.
- November 1. Winter hours start at the main entrance. The gates move from 5 a.m. to 9 p.m. daily to 6 a.m. to 8 p.m. daily, and that schedule runs through April 30.
- November 12. A guided bird walk is on the county calendar from 8 to 10 a.m.
- November 28. A ranger-narrated lake cruise with Scorpion Bay Marina runs 3 to 5 p.m. Reservations are required, and the listed price is $40 plus tax per person.
- December 15. The annual bald eagle closure typically begins. More on that below.
The November 1 hours change matters most for daily routines. It cuts an hour from each end of the day, just as cooler weather makes evening trips more appealing. Anyone used to a 5 a.m. launch or a late walk on summer hours will have to adjust.
Two marinas that stay open after the crowds leave
Fall changes the setting at Pleasant Harbor more than the access. The Pleasant Harbor Water Park, home to the floating H2-Whoa slide and the Whoa Island inflatable park, lists itself as closed for the season starting September 28, though the page doesn't print a year, and its Night Flights are also listed as closed for the season. The marina itself says it's open year-round. It lists Dillon's Bayou for dining, boat rentals, and cruises aboard The Phoenix. Pleasant Harbor's entrance is at 40202 N. 87th Ave. in Peoria and comes with a $10-per-vehicle lake entrance fee.
Dillon's Bayou currently posts hours of 11 a.m. to 8 p.m. Monday through Thursday, 11 a.m. to 11 p.m. Friday, 9 a.m. to 11 p.m. Saturday, and 9 a.m. to 8 p.m. Sunday. Its page already has October 2026 and Halloween promotions up. Lake Pleasant Cruises, which runs The Phoenix, advertises scenic brunch, sunset dinner and Thanksgiving cruises and sends guests to a live booking calendar for dates.
Across the lake, Scorpion Bay's rental fleet includes pontoons, sport boats, kayaks, floating cabins and private charters, along with the sunset, ranger and chef's-table cruises. Scorpion Bay Grill is the marina's restaurant, serving casual food and cocktails. Its site lists more than one weekly schedule, so a quick call before a late-afternoon trip is worth it.
For anglers, the Arizona Game and Fish Department calls Lake Pleasant a popular striped bass fishery and also lists largemouth bass and flathead catfish. The department's October 2026 newsletter gives the general fall pattern: as water temperatures drop, fish start feeding.
December 15 narrows the map
The refill season has a firm boundary partway through. Maricopa County Parks says the annual bald eagle closure typically runs December 15 through June 15. During that time, access to the lower Agua Fria arm is restricted to protect nesting eagles, visitors are asked not to enter by watercraft, and violations can lead to enforcement. Buoys mark the restricted area. If paddling or fishing the lower Agua Fria arm is on your fall list, the weeks between now and mid-December are the window. After that, the arm stays closed through the lake's spring peak and into June.
Getting there while the parkway is under construction
The drive is in transition too. The Lake Pleasant Parkway project covers the road from Loop 303 to 1,000 feet north of the CAP Canal. Construction began in fall 2025, and completion is expected in 2027. The plan widens the parkway to three lanes in each direction, widens the CAP Canal bridge, and adds bike lanes, sidewalks, lighting, drainage and utility improvements. Construction will be part of this year's lake trips from start to finish. Pleasant Harbor's 87th Avenue entrance and the main park entrance at 41835 N. Castle Hot Springs Road in Morristown are the two addresses to plug into a map.
The CAP gauge is still the simplest way to follow the season. It read 1,651.49 feet on October 4, and through the winter the number should rise toward the March and April high the county describes.
At Tiffany Burks, our team has lived in north Peoria long enough to know the lake's calendar runs differently from the rest of the Valley's.

We're glad to talk it through with you.
