The Kromme estuary
(34°9' S;
24°51' E)
lies to the west of the coastal city of Port Elizabeth in the Eastern Cape. The river is approximately 109 km long with a catchment area of 1 085 sq. km. Approximately 29% of the Kromme catchment was under agriculture, mostly temporary commercial dryland agriculture. About 6% of the land-cover was degraded shrubland while roughly 65% was natural; this comprised mainly shrubland and bushland. A number of impoundments (Kromrivier Dam and Impofu Dam) also occur in the catchment and these have affected the hydrology of the system, particularly the estuary. There was very little urban development in the Kromme catchment (less than 1%) and most of this was residential, associated with the holiday resort of St Francis Bay near the coast.
