Water Quality in the San Juan Basin
|
|
The San Juan River Basin is an important
economic as well as environmentally sensitive area that has
become the focus of several outstanding pollution prevention and
restoration efforts in recent years. This site has been
developed to help promote understanding the many complex issues
which affect the Four Corners region today.
|
|
The San Juan River is
a major tributary of the Colorado River. The watershed is
located in the upper northwest corner of the state.

Arising on the
western slope of the Continental
Divide in southwestern Colorado, the
San Juan River flows from the San
Juan Mountains north of Pagosa
Springs, Colorado, and enters the
extreme northwestern section of New
Mexico via Navajo Reservoir in Rio
Arriba County to the west of the
Jicarilla Apache Reservation and the
Carson National Forest. The course
of the San Juan River in New Mexico
turns westward for some 140 miles
before the river turns back north
and re-enters Colorado just a few
miles to the east of the
cartographic landmark known as "Four
Corners". The San Juan River then
resumes its westerly direction
across Southern Utah towards its
confluence with the Colorado River. |
