What Is An Estuary Water samples were taken from within the knysna estuary and various knysna culverts on 16 september 2022. according to the national department of water affairs guidelines, target water quality for recreational use may not exceed 500 e.coli 100ml. the recent water samples were analysed by an independent laboratory to determine e.coli levels. Through a review of current research and available data, the current study evaluated the ecological status of the knysna estuary, identified major pressures and proposed future management and conservation actions. notable impacts included deteriorating water quality, development and resource use pressures. Introduction. the knysna estuary is an estuarine bay. it has been ranked 1 conservation importance. 2004 assessment, knysna scored 100 out of 100. biodiversity importance based on fish, birds, plant and invertebrate. botanical importance, ranked 1 out of 30 warm temperate systems and 3rd overall in south africa. Water samples were taken from within the knysna estuary and various knysna culverts on 18 february 2022. according to the national department of water affairs guidelines, target water quality for recreational use may not exceed 500 e.coli 100ml. the recent water samples were analysed by an independent laboratory to determine e.coli levels.
