Cf. the following:

"(...)as demonstrated by the case of Lake Constance over a
substantial period, it is possible to agree on the regulation of
particular uses and achieve pragmatic accommodations, even between
neutrals and belligerents in time of war, without resolving the
question of whether there is to be a condominium or partition, and
therefore without any formal and complete partition of sovereignty."
