Here is a little more precise information.

Injebreck resevoir is owned by Douglas Corporation but is run by the water board.Local sailing clubs have permission to use it only in the winter months when to water level is high and there is less risk of pollution.

This is from a member of the Douglas yacht club and is correct info.however he did say it is very unlikely that anyone would complain if a canoeist were to have a paddle PROVIDING they kept in near to the banks.

Apart from the pollution issue I am reliably informed that the Islands resevoirs are not to be used for recreational water sports because the water is too deep for safety!!!! can you believe it.
