Rivière du Tarn

The Tarn

The treasures of a limestone river:

  • It is the largest river in the south Aveyron.
  • It descends from the Mount Aigoual massif in the Lozère
  • It has no dams which release sudden amounts of water upstream of the fishing areas
  • It is a river flowing through limestone that experiences sudden increases in level due to heavy rain (spring and autumn)
  • It is classified as 2nd category for fish life from the town of Millau
  • Length of river
  • Average river width is 50 m (165 feet) and the average depth is 1 metre (3 feet)
  • The famous Millau viaduct straddles this section of the river that ends at the Pinet dam
  • It is made up of a succession of large slow flats, ledges and stronger currents
  • Access is relatively easy along the ensemble of the river
  • However, classed as private property, you must have the owner’s permission to cross their property
  • Certain banks are steep and difficult to access, notably on the left bank
  • A road more or less follows the right bank of the Tarn
  • Medium density of brown trout
  • Average size around 35 cm but trophy winning fish are present (over 70 cm)
  • Rainbow trout are omnipresent from releases in the upstream part with fish sometimes reaching excellent sizes
  • Rainbow trout can be fished all year round
  • The catch quota is limited to one trout per day per angler (brown or rainbow)
  • The legal size for trout is 23 cm
  • Fishing techniques that can be used are float, fly, minnows and all types of lure fishing
  • A very precocious river enabling one to fish early in the season but it is more difficult to catch trout in summer
  • Large numbers of non predator fish (chub, common dace, barbell, gudgeon, minnow…)
