  A representation of the quantum affine algebra $U_{q}(\widehat{sl}_3)$ of an
arbitrary level $k$ is constructed in the Fock module of eight boson fields.
This realization reduces the Wakimoto representation in the $q \rightarrow 1$
limit. The analogues of the screening currents are also obtained. They commute
with the action of $U_{q}(\widehat{sl}_3)$ modulo total differences of some
fields.
