In 1903 (top) Cromwell sat high above the junction of the two rivers, the narrower and murky Kawarau joining the broader, crystal-clear Clutha. In the early 1990s, when the Clyde Dam was completed, Lake Dunstan was created, flooding the Cromwell town site. In anticipation, a new town centre had been laid out on higher ground, fronting on to the lake. The new town is shown here in 2005 (bottom), with Lake Dunstan behind.
