The "Dorset & District Water Polo League" [REF] was formed around 1898 between Bridport, Dorchester, Weymouth and Yeovil, with Yeovil winning the 1899 league and Weymouth the 1900 league.
We can only assume that water polo continued to flourish when the soldiers returned from the First World War because when the Dorset County Amateur Swimming Association was formed in 1931 it paid for a senior men's championship shield which is still competed for today.
