About this water

The upper Lot rises on the Aubrac plateau and works its way south-west through rolling granite country before the broader river takes over below Entraygues. The headwater and upper-middle sections are proper freestone trout water: wild brown trout and grayling in clear runs between riffles and pocket water, good olive and caddis hatches, and enough quiet to make the fishing feel like its own reward. The Aubrac gives it a particular character — cold water off the high ground, responsive flow after the frequent plateau storms, and a short snowmelt bump that shapes the early season. Standard upstream dry-fly work in the slower glides, tight-line nymphing in the faster runs. From about May onwards the fishing is consistent through to September, with the grayling extending the season into October in the deeper pools.
