The best water activities near Merced this week are at Lake Yosemite, Lake McSwain, and Lake McClure, plus the Merced River at Briceburg. For Central Valley water activities in October, that means kayak and paddleboard rentals on Lake Yosemite's sandy beach, calm swim beaches at the McSwain and McClure recreation areas, and free swimming holes in the Sierra foothills near Mariposa. All four spots are open this week, and each is listed below with hours, costs, and an official link.
The summer water season may have peaked, but the reservoirs stay open, and fall is one of the best times on the water in the foothills: cooler air, fewer crowds, and warm afternoons that are perfect for a lake day. This week's picks run from Merced east to McSwain, Mariposa, and the Merced River corridor, and everything below is verified against the official park, district, and agency pages. If you missed the plan-your-weekend edition, our weekend guide for October 9-11 has the rest of the calendar, including the Lake McSwain trout derby and farmers markets.
Central Valley Water Activities: This Week's Four Picks
Between them, the four picks below cover a swim beach with rentals (Lake Yosemite), a calm no-wake paddling and swimming lake (Lake McSwain), the biggest lake in the area with open swim lagoons and launch ramps (Lake McClure), and a free river swimming area (the Merced River at Briceburg). The Merced Irrigation District manages the first three, so the entry rules and fees line up, which makes a multi-lake day trip easy to plan.

Lake Yosemite in Merced: Swim Beach, Boat Launch, and Kayak Rentals
Lake Yosemite is the go-to summer lake for Merced, sitting about 10 minutes northeast of downtown on North Lake Road at 5714 North Lake Road. The Merced Irrigation District took over recreation management at the lake in February 2026, and it runs the swim beach, boat launch, and picnic grounds. What it offers: a sandy swimming beach, beach volleyball courts, playgrounds, picnic tables, restrooms, a boat launch, and on-site kayak and paddleboard rentals from The Padyak Shack. Fishing is popular from shore and small boats, and the lake makes a relaxed half-day outing with kids.
Hours: gates open 7:30 AM and close one hour after sunset; boats must be off the water 30 minutes before sunset. Cost: day use is $10 per vehicle per day, plus $9 per day per boat or trailer. Annual vehicle passes are available and also cover Lake McClure and Lake McSwain. Rentals: The Padyak Shack rents kayaks and paddleboards on-site; single kayaks run about $15 for an hour and $60 to $80 for a full day.
Rental hours shrink as the season winds down, so call The Padyak Shack or confirm on its page before heading out. For everything else, the official Lake Yosemite page posts current hours, fees, and closures. Weekday mornings and late afternoons are the quietest windows, and the beach faces west, so sunsets over the water are the classic Lake Yosemite moment.
Lake McSwain near Snelling: A Calm No-Wake Lake for Paddling and Swimming
Lake McSwain, about 6 miles from Snelling in the Sierra foothills east of Merced, is the family-friendly water spot in the McSwain community. It is a small, calm reservoir with a 10 MPH no-wake limit, which makes it ideal for kayaks, paddleboards, canoes, and small fishing boats, with none of the ski-boat chop you get on bigger lakes. The McSwain Recreation Area has a swimming beach, picnic tables, showers, a boat launch, and the Lake McSwain Marina, which rents boats and runs the Reel Deal Market and Cafe on limited weekend hours in the fall.
Hours: the park is open 24 hours, 7 days a week. Day-use passes are valid sunrise to sunset, and a separate night fishing pass (6 PM to 10 AM) is available. Cost: $10 per vehicle per day, $9 per day for a boat or trailer, $3 per day for a motorcycle. Marina: fall hours are typically Friday 9 AM to 4 PM, Saturday 9 AM to 5 PM, and Sunday 9 AM to 4 PM; call (209) 378-2219 to confirm. The Splash-N-Dash floating inflatable water park operates Memorial Day weekend through Labor Day, so it is closed for the season now, but the beach itself is open.
One event worth circling this week: the Fall Classic Lake McSwain Trout Derby is scheduled for Saturday and Sunday, October 10-11, with fishing starting around 6:00 AM. Recent derbies have charged roughly $25 to $35 per adult, with kids under 16 fishing free with a paid adult, plus day use. Registration runs through the FishDonkey app, and the 2026 details are still being finalized, so confirm on the official events page at lakemcclure.com before you go. The lake is stocked with rainbow and brown trout, and shore fishing is easy from the grassy banks. Full details are on the official Lake McSwain page.
Lake McClure: Swim Lagoons and Open Launch Ramps for Private Boats
Lake McClure is the big water in the region, a 7,000-acre reservoir on the Merced River behind Exchequer Dam, about 35 to 40 minutes east of Merced by way of Snelling. It is the place for watersports with your own boat, waterskiing, and long lake days, and it keeps two swim lagoons open this week: Barrett Cove Swim Lagoon and McClure Point Swim Lagoon. Launch ramps currently open include McClure Point South and North, Barrett Cove South, Bagby, and McSwain, so private boats have several easy options.
Hours: open 24 hours, 7 days a week; day-use passes run sunrise to sunset, with a night fishing pass available. Cost: $10 per vehicle per day, $9 per day for a boat or trailer, and annual passes around $125 that also work at Lake McSwain and Lake Yosemite. Know before you go: the official status page currently lists the Horseshoe Bend Swim Lagoon, Barrett Cove Marina, and the marina's Upper Store as closed, so plan to bring your own boat and supplies and double-check the status banner before the drive. Camping is available at Barrett Cove and other campgrounds if you want to make a weekend of it, and the marina closures mean stocking up in Snelling or La Grange first is the smart move.
The official Lake McClure and Lake McSwain site posts the current ramp and facility status at the top of the page, plus the full fee schedule. For boaters, the lake phone line is (855) 800-2267.
Merced River at Briceburg: Free Swimming Holes Near Mariposa
For a free water day in the foothills, head up Highway 140 to the Merced River Recreation Management Area east of Mariposa. The Briceburg Visitor Center sits about 12 miles east of town, and Cable Rock Day Use Site, about 1.4 miles downstream on the old Yosemite road, is the most popular swimming spot: a river beach with a jumping rock for adventurous swimmers. More swimming holes line the unpaved Briceburg Campground Road behind the visitor center, and the Merced River Trail leads to quiet river access. Day use and swimming at the Briceburg area are free; only the campgrounds (McCabe Flat, Willow Placer, and Railroad Flat) charge, at about $20 per night, reservable on Recreation.gov.
Hours: day use is open daylight hours at no charge. Cost: free to enter; the only fees are the campgrounds. Know before you go: October river water is cold, flows drop after the summer snowmelt, and there are no lifeguards, so treat swimming as at-your-own-risk and check the current river flow before getting in. The area is managed by the Bureau of Land Management, and the official BLM Merced River page has maps, campground details, and alerts. It is also a beautiful fall drive, with the oaks turning gold along the river canyon.
Water Quality and Beach Advisories This Week
As of this writing, no current algae blooms, beach closures, or water-quality advisories are posted for any of the four featured spots: Lake Yosemite, Lake McSwain, Lake McClure, and the Merced River at Briceburg. The one advisory to keep on your radar is Eastman Lake, about 23 miles northeast of Chowchilla near Raymond. In late August 2026, Madera County officials urged visitors to avoid water contact at Eastman after a harmful algae bloom was found near the boat ramps, and that advisory is the most recent official notice. Treat Eastman as fish-and-boat-only for now, do not swim or let pets in the water, and confirm the current status on the state's California HAB Reports Map before any visit.
Two standing notes: Lake McSwain carries a long-standing state fish-consumption advisory based on mercury, so follow the posted eating limits for fish taken from the lake, and at every reservoir, watch posted signs, keep kids within reach at swim beaches, and never swim near boat ramps or dam structures. These public spots are open to everyone, and Monica offers equal service to all.
Why a Full Water Season Matters for Home Sellers
A community with a swim beach 10 minutes from downtown, a no-wake lake for kayaking, a 7,000-acre boating reservoir, and a free river canyon in the foothills is a community with a strong quality of life, and that is exactly what buyers experience when they tour neighborhoods in Merced County. Whether you are renting a kayak at Lake Yosemite, fishing the McSwain trout derby, or watching the sunset at Barrett Cove, you are living the local story that sells homes. When it is time to list, having an agent who knows these communities from the inside out makes the difference between a for-sale sign and a sold sign.

Frequently Asked Questions About Water Activities Near Merced
Where can I rent a kayak near Merced?
The Padyak Shack rents kayaks and paddleboards on-site at Lake Yosemite (5714 Lake Rd, Merced). Single kayaks run about $15 per hour and $60 to $80 for a day rental. The shack trims its hours as the season winds down, so call ahead or check its page before you go. Lake McSwain Marina also rents boats on limited weekend hours during the fall.
Can you swim at Lake McSwain?
Yes. The Lake McSwain Recreation Area has a swim beach with picnic tables, showers, and a no-wake 10 MPH limit that keeps the water calm for families. The Splash-N-Dash floating inflatable water park operates Memorial Day weekend through Labor Day, so it is closed for the season right now, but the beach itself stays open.
How much does day use cost at the MID lakes?
Day use at Lake Yosemite, Lake McSwain, and Lake McClure is $10 per vehicle per day, plus $9 per day for a boat or trailer. Annual vehicle passes run about $125 and cover all three lakes managed by the Merced Irrigation District. Entering with a motorcycle is $3 per day.
Are there any water advisories right now?
As of this week, no current algae or water-quality advisories are posted for Lake Yosemite, Lake McSwain, Lake McClure, or the Merced River at Briceburg. Eastman Lake near Chowchilla is the exception: Madera County officials urged visitors in late August 2026 to avoid water contact there due to a harmful algae bloom, so do not swim at Eastman until that advisory is lifted. Check the California HAB Reports Map for the latest status.
Is the Merced River good for rafting in October?
Commercial rafting on the Merced River runs in the spring and summer snowmelt season, and by October the guided trips have typically wrapped up and flows have dropped. The Briceburg area is still a great free stop for hiking the Merced River Trail and rock-hopping at the swimming holes, but treat October swimming as at-your-own-risk, cold water, and always check the current river flow before going near the water.
