Sub-Regional Basin Basics

The results of this research are primarily presented as the statistical tables and maps of individual subregional watersheds, the basic unit of the study. This detailed information is too involved to list on this web page, so we’ve created some very lengthy tables in PDF format are available via the links below.

In all cases, the data is compiled for each sub-regional basin by BASIN NUMBER. You must know the basin number you are looking for. You can find your basin number by:

Sub-regional Basin Name
	Sub-regional basin number and name* Regional basin name Major basin name Area in acreage and square miles Sub-regional basin unique ID
A Map (zoomable pdf)
	In Adobe reader, you can turn layers in the pdf on and off using the layers tab on the left side.

For reference, we also have a list of Sub-regional Basin Names Sorted by Sub-regional Basin Number
	Sub-regional basin number and name* Regional basin name Major basin name Area in acreage and square miles Sub-regional basin unique ID

* Basins are numbered in a nesting fashion. The first of the four digits represents the Major Basin Number. The second digit represents the Regional Basin and the last two digits represent the Sub-regional Basin.

Land Cover and Land Cover Change by Sub-Regional Basin

Land Cover and Land Cover Change by Sub-regional Basin

1985 Area for 7-class simplified land cover
1985 Percentage of the Total Area of 7 classes

Buffer Zones

Basin Area within and outside each buffer zone

Total area of each sub-regional basin
Water area for each sub-regional basin

For each sub-regional basin and each of the 100ft, 200ft and 300ft buffer zones

Acres outside of the buffer and water area
Buffer area
Percent of basin cover by the buffer zone
Percent of basin covered by the buffer zone and water

Land Cover in Riparian Zones by Sub-Regional Basin

Focus on Natural Vegetation

Natural Vegetation

For each sub-regional basin:

Total Area and Percentage of Natural Vegetation
100ft Buffer Zone Area and Percentage of Natural Vegetation
200ft Buffer Zone Area and Percentage of Natural Vegetation
300ft Buffer Zone Area and Percentage of Natural Vegetation
In the 100ft Zone, percent of Natural Vegetation compared to the Entire Basin
In the 200ft Zone, percent of Natural Vegetation compared to the Entire Basin
In the 300ft Zone, percent of Natural Vegetation compared to the Entire Basin
