Matlock Fishing

The solid line is measured Environment Agency data from Matlock. The future section will add our own 6/12/24/36-hour forecast as a separate line, with its accuracy tracked against subsequent actual readings.

These percentages are an early rules-based estimate using season, time of year, cloud, light, pressure and weather. They are not yet trained on your Derwent observations.

As you log actual insects seen, hatch intensity and timing, this will progressively become a Derwent-specific predictor rather than a generic calendar.
