"River flow refers to the quantity of water passing a point in the river over a certain amount of time. Different rivers have different flow patterns, such as sharp peak flows following rain with low flows in between, or high spring flows from snow melt. These flow characteristics affect how much water is available for irrigation, drinking water, hydro–electric power generation, and recreational activities such as fishing and boating. River flows are also very important for maintaining the health and form of a waterway.

This dataset relates to the "Geographic pattern of natural river flows" measure on the Environmental Indicators, Te taiao Aotearoa website. "

Raw data, and state and trend calculations for key groundwater quality indicators, including nitrate-nitrogen, ammoniacal-nitrogen, dissolved reactive phosphorus, dissolved iron, dissolved manganese, total dissolved solids content, and electrical conductivity.

Statistics reported on include:
- median and median absolute deviation
- percentiles
- trend magnitudes
- statistical test p-values (from the Mann-Kendall trend test, Kruskal-Wallis test for seasonality, and sign-tests and Wilcoxon rank-sum tests for distribution differences).

Regional councils issue resource consents for the taking of fresh water for various purposes, including irrigation, drinking, hydroelectricity, and industry. Water can be taken from surface water or groundwater.

The file provides the primary source and primary use of the water take for each consented take.

"Wetlands support unique biodiversity and provide important services. They clean water of nutrients and sediment, help dampen floods, provide habitat, and act as carbon sinks. They are also valued for their spiritual and cultural significance and as important sources of food and materials, such as flax. Draining them for agricultural and urban development has reduced their extent. Understanding this reduction provides insight into the loss of biodiversity and natural function.
This dataset relates to the ""Wetland extent"" measure on the Environmental Indicators, Te taiao Aotearoa website. "

"Fine sediment is the collective term for inorganic particles deposited on the streambed less than 2mm in size. Urban development and agriculture and forestry around waterways can increase the amount of sediment entering river systems. Sedimentation can clog space between pebbles that are used by aquatic insects and fish, alter food sources, and remove sites used for egg laying. Excess sediment can affect the appeal of rivers and streams for recreation.
This dataset relates to the ""Streambed sedimentation"" measure on the Environmental Indicators, Te taiao Aotearoa website.
