Here’s a release from YSI about efforts to monitor water quality in Grand County:

“Good water quality benefits everyone,” says Jane Tollett, Director of Grand County Water Information Network (GCWIN).

Assessing the health of the Colorado and Fraser Rivers is a tall order for Tollett. There is a limited amount of water, with the Upper Colorado Watershed supplying water to meet both the local needs of residents, ranchers, cold-water fisheries and recreation, along with eastern slope agriculture and the increasing populations along the front range from Denver to Fort Collins.
