Description:

Okavango River Basin Technical Diagnostic Analysis: Environmental Flow Module Specialist Report - Country: Namibia, Discipline: Water Quality.

Summary / Notes:

This study dealt with the physiochemical characteristics of the Okavango River on the Namibian side. Two sites were selected as part of an Environmental Flows Assessment exercise and a thorough literature review was conducted prior to the actual monitoring and assessment of findings. The most outstanding finding of the literature review is that the quality of thernOkavango River is generally very good and contains very low concentrations of nutrients, turbidity and suspended solids (Bethune 1986, Bethune 1991, Cronberg et al, 1995, Turton, 1999, Hay et al 2000, Trewby 2003 , Anderson 2006). The major gaps that were identified are the inability of detecting measurablernconcentrations of nutrients by the methods that were used in all the studies and the absence of monitoring chlorophyll a concentrations in the Namibian waters. Seven (7) indicators of water quality were identified and monitored at both the selected EFA sites for the dry season and the wet season. The monitoring was conducted in the mainstream of the river as well as in the isolated floodplain pools and backwaters of the river system. The outcome of the results of this monitoring reflects the findings of the existing studies to a great extent in terms of the seasonal variations of the water quality throughout the river system.
