The old Whitwarta School (1879–1951) still stands at the northern end of the village on Bowman St, as does the Post Office at the southern end. The church and Whitwarta Hotel along the Kadina Road were damaged by floods during the 1900s, and were demolished as a consequence. The last flood occurred in September 2010 (the previous flood occurred in summer of 1998). A number of "Eucalyptus camaldulensis" sprouted on the flood plains and riparian zone shortly afterwards, some of which have been fenced-off by local farmers to avoid stock damage. A management plan for the River Wakefield was carried out in 2000, which included recommendations for the amelioration of water quality and flow at Whitwarta. Up until the late 1970s, it was common for the River Wakefield to flow every winter. Damming of the river upstream has impacted flows to the point that the River Wakefield now flows about once every five years. The trees around Whitwarta have suffered in recent years because of the rise of salinity in the soil. The National Trust of South Australia has listed a stand of "Eucalyptus largiflorens" (River Box) at Whitwarta on the significant tree registrar. These trees, which are located approximately north of the River Wakefield and about west of the Halbury-Whitwarta intersection, are the only Eucalypts of their kind in the district. Local farmers say that these trees sprouted after a flood in the early-mid 1900s.
