Long Term Data Acquisition

A Hydrologic Field Station was installed on campus in 1992, and has been monitoring surface flows and water levels, temperature, electrical conductivity, pressure, etc. in the groundwater ever since. This installation and its dataset provide students with insights into the challenges presented by evolving technology in maintaining a meaningful and continuous record of simple environmental variables over an extended period of time.

Surface Flow

This concrete weir is at the point where the Canacadea Creek enters the AU campus. Its design, and the instruments and computers in the shack, permit accurate determinations of the volumetric flow rate, or discharge, of the creek.

Drilling the wells 

The glacier left quite a mixture of soils in the Alfred valley. Porous aquifers and impermeable clay layers were revealed as the drilling team penetrated 300 feet to install the monitoring wells

The wells

Seven groundwater wells, fully instrumented to measure and record water levels, temperature, electrical conductivity, pressure, etc.

USGS monitoring well

The USGS operates a satellite water-level telemeter station at the same location: USGS 421512077472801 Local number, Ag-261. Data can be obtained on the web.
