The Agreement explicitly indicates that it applies to transboundary waters of the Narva River Basin, including Pskovsko-Chudskoye/Peipsi Lake. Over time, the competence of joint bodies has expanded to include fishing and fisheries, water allocation, irrigation, power generation, construction of water facilities and bridges, and the protection against floods. For example, in the agreements concluded between or with participation of EECCA States from the early 1990s, groundwaters are included in the competence of some joint commissions (agreements 2, 8, 20 in table 1) and plenipotentiaries (agreements 1, 4, 9, 18 in table 1).
