Temperature and Electric Conductivity
What is Electric Conductivity? Electrical conductivity is a measure of water's ability to conduct electricity, and therefore a measure of its ionic activity and content. In short, it is an indirect measure of the presence of dissolved solids such as chloride, nitrate, sulfate, phosphate, sodium, magnesium, calcium, and iron, and can be used as an indicator of water pollution.

7 Sites
7 sites are monitored on the inlets and outlets of the Three Lakes system (Lake Granby, Shadow Mountain Reservoir, and Grand Lake).
Types of Data
These sensors are specialized to collect stream temperature AND electric conductivity data, making them different from the sensors used in our stream temperature program. They collect both of these measurements every 15 minutes.
Monitoring Purpose
The T&EC program is intended to track the presence of dissolved ions (metals) going into and coming out of the Three Lakes system.
