  The lakes of Wada are three disjoint simply connected domains in $S^2$ with
the counterintuitive property that they all have the same boundary. The common
boundary is a indecomposable continuum. In this article we calculated the
Minkowski dimension of such boundaries. The lakes constructed in the standard
Cantor way has $\ln(6)/\ln(3)\approx 1.6309$-dimensional boundary, while in
general, for any number in $[1,2]$ we can construct lakes with such dimensional
boundaries.
