This is the station Exploits River Below Noel Pauls Brook WSC 02YO011, a typical streamflow gauging site. The recording instruments and other electronics are in the shed on the right. The tower on the left is for a cableway that extends across the river. The cableway is used for measuring streamflow at intervals across the river. These measurements are used to create a stage/discharge curve, which can then be used to indicate what the streamflow is for any given water level.


The shed is usually a short distance from the river and requires no external electrical service. The instrumentation is powered by battery packs that are charged by a small solar panel mounted on the roof. The antenna that is used to transmit to the GOES satellite is mounted on the top left of the shed. In this picture the corner of the solar panel can be seen mounted on the bottom of the antenna mast.


Inside the shed are the various recording instruments and the wiring panel which connects the recording devices to instruments that are located outside the shed.


An example of an external instrument can be seen in this picture of the climate station Burgeo Road Near Buchan's Access. On the right side of the picture is the rain gauge. The rain gauge has to be located in a clear area at a certain height from the ground. The dangling fins that surround the top of the gauge bucket are a wind alter shield which minimizes the effect of wind on the amount of precipitation collected.


Another type of external sensor is for air temperature. In this picture the temperature probe is mounted on the back of shed. The flat panel on top of the probe is to prevent the sun from directly heating the probe so that a true air temperature can be recorded.
