Coming winter period the sailing area Pikmeer, Tijnje and Rjochte Grou will be made back on depth. The maintenance of this waterway is the past few years left undone.
The City of Boarnsterhim launched together with the province of Fryslan on 14 november 2013 this project. It is a boost for the tourist attraction of Grou. The current water depth is in places inadequate for sailboats. After dredging the Pikmeer is accesssible to big (sail) ships. The commission Grouwster skutsjesilen is also happy that the waterway is made deeper. People can later on ''stuck a sword'' on the entire lake and that's better for the competition.
