NIWA has calculated estimates of environmental conditions across the entire New Zealand river network, including hydrology, ecology and water quality metrics. This interactive webtool allows you to map and interrogate these estimates see National Estimates tab.
In addition, you can intersect the NIWA estimates with publicly-available council planning layers see Council Layers tab and view a simplified representation of the river network. Please refer to Help tabs on both the National Estimates and Council Layers tabs for more information about the different datasets and how you can interrogate them.

Thank you to various Regional Council staff for making spatial data available. Whilst NIWA has used all reasonable endeavours to ensure that the information contained in this website is accurate, NIWA does not give any express or implied warranty as to the accuracy of the information contained herein.
National estimates at unvisited sites are designed to represent regional patterns and should not be used to replace site-specific studies. Select the Create Colour Bins option to categorise numeric data into three classes. The popup slider can be used to set the breaks. Select a reach marker to draw the predicted flow duration curve top plot and wetted useable width under different flows for selected species bottom plot.
Select a reach on the map to highlight the connected upstream and downstream reaches. Select X and Y variables to generate plots of the highlighted reaches top plots compared to all mapped reaches bottom plot.
NIWA's national estimates are based on statistical models that relate observed patterns with landscape-scale patterns and then generate estimates on the entire New Zealand river network.
The estimates represent conditions in the recent past. A range of hydrological, ecological, environmental and water quality-related metrics have been plotted onto Version 1 of the National River Network River Environment Classification, RECv1.
Circles represent the centre of an NZReach a segment of river between two confluenceswith the size of the circle indicating the stream order.
Each circle is coloured by the estimated value of the selected variable, indicated by the map legend. A description of each variable can be viewed when the variable is selected in the Options tab under National Estimates or the Plots tab under Council Layers. A reference and link where available to the relevant paper or report is also provided for more information about how the metrics were calculated.

The Map Panel allows you to visualise a range of spatial data, including NIWA's national estimates, some publically-available Regional Council layers and a simplified version of the New Zealand river network. These data can be turned on and off using the check boxes in the top right of the map panel.
The Options tab allows you to change how the national estimates are viewed by switching variables, transforming the data to allow better differentiation between sites and changing the number and size of reaches that are plotted using the stream order slider.
We don't recommend selecting all stream orders across a whole region as they are very slow to plot. The Flow and Habitat tab allows you to view the estimated flow duration curve and estimates of the weighted usable width WUA for various fish species for the selected reach. The Catchment Plots tab allows you to graph estimates of the selected variable upstream and downstream of a specific reach.
Check Enable Tracing to identify reaches upstream and downstream of any selected reach marker. Select available Regional Council layers to map and colour them by the metadata provided using the two dropdown menus.Now that you have made a model watershed, you'll check out real watersheds across the contiguous USA and explore the one in which you live.

Show me an explanation. Rivers of the smaller watersheds all empty into the Mississippi River. Every place within the Mississippi watershed eventually flows down the Mississippi River. Major tributary rivers that flow into the Mississippi are considered as separate watersheds within the Mississippi system. Show me another way to access this page.

Show me how to save the file. Show me what to do if there's no label inside my watershed. Right along the coastline, water flows directly downhill into the ocean along small streams, so these areas are not considered as parts of inland watersheds. The topography of some regions funnels all the precipitation to a point within the watershed.
In these basins, water gathers in a land-locked lake rather than flowing to the ocean. If the map does not show a watershed label for your area, select one that is nearby for your investigation.
In the case of a landlocked watershed, select the larger watershed that contains the on in which you live. Show me more about information about watersheds near Texas.

This map will show you! Or just having a general knowledge of your own area and region. The map tool also has a topographical base and additionally enables the ability to print a map based on your selection.
No matter where you live, it is very good preparedness to know where your water sources are located! Having a Road Atlas Map For Each State will also indicate many or most of the rivers, streams, and lakes in your area.
I always keep these maps in my vehicle for my own state and the surrounding states. Another resource: State Fishing Maps. Thie topic of rivers and streams is a very sore subject in my family.
My wife and her sister own a ranch of 10, acres and it has been in the family since Last summar I was out on the ranch and saw 4 men surveying a creek stream and I drove over to ask them what in the hell were they doing and who gave them permission to be there.
Unless it rains a storm this creek is only 4 feet wide and about 6 inches deep. I told them to leave and they refused to leave so I called the local sheriff. Xxxxxx the state controls this waterway. They can come here any time they want to. You must get the states permission to use water from the creek. You need a permit to dam the creek or build a creek crossing of any kind.
You can not run a barb wire fence across the creek. They government defines a waterway as any land that is covered by flowing water at any time of the year. My lawyer confirms the above. So now I ask who really owns this land, my wife or the government? We have never sold the land and I am the one that pays the property tax.
Something has really gone wrong in this country and I am mad as hell. I feel your pain.
