Live from the National Weather Service API for the lake's coordinates (39.3432, -121.3171). The nearest station may be several miles away. NWS forecast for Merle Collins Reservoir. No live water-temperature sensor is shown because we haven't found a public one for this lake.
Based on solunar theory, an estimate. Major periods (about 2 hours) center on when the moon is directly overhead or underfoot; minor periods (about 1 hour) center on moonrise and moonset. The 0–100 activity score rises during those periods and gets a boost near sunrise and sunset and around the new and full moon. Weather, water temperature and pressure often matter more. Sun and moon times are calculated in your browser from the lake's coordinates with standard astronomy formulas, shown in PT (America/Los_Angeles), and accurate to within a few minutes.
