Merderet is a 36 km long river in Normandy, France which is
tributary to the Douve River.
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
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.
