T\u00e9 moltes roques perqu\u00e8 les truites puguin pondre els ous. I aquestes condicions fan que hi hagi tamb\u00e9 molts macroinvertebrats que els hi serveixen d\u2019aliment.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">TRAM MITJ\u00c0: L\u2019aigua \u00e9s entre regular i dolenta.

Est\u00e0 contaminada, de color marron\u00f3s i bruta.
