There is no beach on record at Millerton Lake in the datasets this guide reads. The nearest mapped swimming spot is Huntington Boat Ramp & Launching Site on Huntington Lake, roughly 30 miles away. Absence from these datasets does not mean the water is closed, only that no agency lists a beach.

Most California day-use areas open for the summer season and close outside it. Water temperature is not measured at this lake by any public agency we read. Inland lakes are not monitored the way ocean beaches are, so posted signs matter more here.
