Hydrology
The river has relatively high turbidity and its brownish water is somewhat low in velocity due to the slight gradient of the watercourse; pH levels have been measured at 8.31 near the Chateau d'Isle Marie and electrical conductivity of the waters have tested at 61 micro-siemens per centimetre. At this reference location, summer flows are typically in the range of 250 cubic feet per second (7.1 m3/s).
