SAN JOAQUIN R BL FRIANT CA · Oct 11, 7:30 AM UTC
Good for fishing (83/100), from 6 available inputs. Supporting this: Wind 0 mph from the west. Measured water temperature 55°F from a representative gauge 6.3 mi away. Provisional data. Not available from a verified source for this lake: pressure trend. Confidence is moderate (82%) because some inputs are unavailable or older than ideal.
Excellent for boating (99/100), from 4 available inputs. Supporting this: Wind 0 mph from the west. Gusts to 5 mph. Not available from a verified source for this lake: visibility and conditions, verified water access. Confidence is moderate (84%) because some inputs are unavailable or older than ideal.
Fair for sailing (61/100), from 4 available inputs. Supporting this: No active official alerts for this lake. Gusts are within 5 mph of sustained wind, so the breeze is steady. Working against it: Wind 0 mph is light; expect limited sailing. Not available from a verified source for this lake: visibility. Confidence is high (88%).
Excellent for kayaking (99/100), from 5 available inputs. Supporting this: Wind 0 mph from the west. Gusts to 5 mph. Confidence is high (90%).

Individual boat ramp GPS coordinates are maintained under the jurisdiction of California State Parks. Public boaters should verify seasonal launch water levels, gate hours, and daily vehicle/vessel fees before traveling.
Known for its reliable water levels and open navigation, Millerton Lake in CA welcomes visitors for boating, paddling, and shoreline recreation. The waterbody supports an active angling community pursuing both native and stocked sportfish. Verifying ramp depth and seasonal regulations helps ensure safe launch operations.
Valid freshwater sport fishing license issued by California Department of Fish and Wildlife (CDFW) is required for anglers age 16+. Digital license on mobile is accepted.
Mandatory Clean, Drain & Dry inspection. Out-of-area craft require on-site Aquatic Invasive Species (AIS Quagga/Zebra) inspection or decontamination before launch. USCG life jackets required for all.
Managed under state park jurisdiction. Standard vehicle day-use entry fees or valid annual state park passes are required at entry gates and designated day-use areas.
High-speed motorboating, pontoon cruising, wakeboarding, and water skiing across main channels. Target gamefish include Spotted Bass, Largemouth Bass, Striped Bass. Morning hours typically provide optimal glassy conditions for kayak and stand-up paddleboard (SUP) touring.
Warm water temperatures, peak swimming, active watersports, and open full-service campgrounds. Highest weekly attendance; plan early arrivals on summer weekends.
Spring pre-spawn and fall feeding transitions create prime trophy angling conditions. Cooler air, lower boat traffic, and vibrant seasonal shoreline foliage.
Mild year-round outdoor climate. Uncrowded waters, active winter bass and crappie fishing, and open year-round boat launch access.
