As well as maintaining a network to monitor and predict floods, Marlborough District Council hydrologists monitor rainfall, river flows and groundwater levels, analyse data and provide information and advice to groups both inside and outside Council.
Council maintains a network of river sites using electronic technology. Data from most sites is transmitted direct to Council's Blenheim office.
The collection of data and subsequent analysis allows information to be used for other projects such as the determination of low flows in rivers for resource consents, water allocation, in-stream habitat surveys and groundwater recharge investigations.

Ecology of Rivers
The land use around the stream and the land use in the catchment are both very important influences on the overall health of the waterway.
River Water Quality
River water quality is routinely monitored to ensure that water quality is of a high enough standard to protect the values of the river. River values include; ecological values, recreational values, irrigation and drinking water values, aesthetic values etc.
A wetland is an area of land which is covered in, or wetted by, water for most (but not necessarily all) of the time.
