Welcome to the 2012 Status of the Watershed Report designed to answer the question, “How is the water?” in the Upper White River basin in Arkansas and Missouri.
The 2012 Status of the Watershed Report interprets water quality data that was collected in 2012 and compiled in March 2013. It is intended for the general public to gain a basic understanding of water quality in the Upper White River basin and to answer the common question “How is the water?”. The report is not meant to be used as a basis or guideline for regulatory purposes or to confirm or discredit any other research or water quality regulations. It provides a “big-picture” look at water quality in the basin and is intended to educate the public and provide feedback to the volunteers.
There are many groups collecting water quality data in the Upper White River Basin (UWRB). Some are paid professionals working for government agencies at the local, state and federal levels, while others are volunteers venturing to the water out of genuine love and concern. This report is a summary of data from 11 monitoring projects including 5 volunteer groups. The methods used to generate the water quality data differ from one project to the next and the sites evaluated included small streams, larger rivers, reservoirs and tail-waters. The number of samples from a given site range from 1 to >40. Given all of these differences in the data we know there can be no one “valid” value that could be used as a cut-point for our data range when we rank the site and the parameter as “high, “moderate” or “low”. Any number used might be appropriate for some of the sites, but not all of the sites. The cut-points used in this report were chosen to allow for a comparison of sites only within the White River basin and were not intended as a final say on what is or isn’t good water quality.
This report utilizes over 4,000 water quality measurements taken on 1,600 occasions at over 160 locations in the UWRB. We have condensed that information into an interactive online map (below) where you can zero in on each site and parameter and an 8 page printed report.. At the bottom left hand side of the map is a link to take you to a larger version. Just below the map you will find information relating to the map and the information it contains.
In addition, you can view the numeric averages on a spread sheet sorted by site name by clicking on this link: Numeric Site Averages

Clicking a pin on the map above will bring up a chart showing the site's water quality ratings. Here is an example of a chart:
If a parameter was measured at the site, the chart will show a colored box that is either green (high quality), yellow (moderate quality) or red (low quality):
Average data for all sites are presented in spread sheet form in a downloadable PDF file. The information is sorted by the site name. Values for dissolved oxygen represent the percentage of values meeting criteria; values for all other parameters are geometric means. The table also shows each site's overall rating and the number of sampling events (range = 1 to 22).
You can click and drag to move around on the map, click the plus or minus sign to zoom in and out, or switch between a street map and a satellite photo by clicking "Map" or "Sat" on the top right.
