|Alabama Water Watch has developed a suite of online tools for storing, retrieving, examining and exploring AWW water data. Citizen volunteer monitors, and the public, can access AWW water chemistry and bacteriological monitoring data, displayed as line graphs and bar graphs. The search can be done through either a map or table interface.
By clicking the Data by Table image, shown below, you will be directed to a table with a list of sites that can be searched by one of the ten AWW Watersheds (as defined in the AWW Water Chemistry and Bacteriological training manuals; click here for a review of AWW watersheds). You will notice that the Alabama River Watershed is displayed, by default, since it is the first based on alphabetic order.
First, select the type of water data, Bacteria or Water Chemistry, that you want to view in the Chart Type box at the top-right of the page.
Then, select the desired AWW Watershed, and then the desired AWW monitoring Group in that watershed.
You will then be taken to a table listing all of the monitoring sites for that group. Note, if you don’t see a known site displayed that you are looking for, it is because there is no data at that site for the data type that you chose. For instance, if you select Bacteria for your Data Type, go to the Watershed and Group that you are looking for and don’t see the site, this means that there is Water Chemistry data for that site, but no Bacteria data – just go back to the top of the page and switch to Water Chemistry data to explore data for that site.
To facilitate your data search, most columns in the table can be sorted in either ascending or descending order by clicking on the column title (the only column that cannot be sorted is the Site Maps column). The Site Maps icon opens a google map displaying the selected monitoring site in the center.
Note: Water data can also be searched by Hydrologic Unit Code, or HUC, Watersheds (click here to learn more about USGS watershed categorization based on HUCs). To search based on HUC watersheds, up at the top of the page next to Search, click the HUC Watersheds radio button, then select the desired HUC6 Basin and within that basin, the desired HUC10 Watershed.
As in the past, users have the option to graph either a single water quality variable, or two variables, by selecting the variable(s) on the drop-down boxes next to Y1 or Y2. The scale on both axes can be adjusted by clicking on the Y1 or Y2 icons and then inputting the the desired minimum and maximum values on each Y axis. Data ranges can be adjusted to the desired time frame desired by selecting dates in the boxes to the right of From and To. Click the Chart button to update changes, and the Back to Sites button to return to the list of sites.
Another option to explore the AWW citizen data is searching monitoring sites by watershed using google map. This option allows the user to search by anyone of the traditional ten major river basins used in the AWW site code system.
We hope that AWW online data visualization becomes a valuable tool in your outreach, education, and watershed stewardship efforts!
