Steve installing the new Gov. Spring scale on the 2 x 4 which is coated with a blue paint to minimize water absorption. |
 |
The water gauge at the old gauging station is marked in 10ths of feet. *Click on the picture to view a QTVR (4870) taken from the stream to the right. |

|
Side view of the new gauging station: scale is on the 2 x 4 next to the bridge, weir to the right. |
 |
The weir is constructed from water-proofed plywood, held in place by two steel posts plus other wood supports. |
 |
|
A view at low water looking towards the spring. Note the water plants that tend to clog the "V" notch of the weir. Also note the clarity of the water. |
 |
A view towards the actual spring from slightly downstream of the weir shows the long and narrow pool surrounded by willow trees. |

|
Pete attaches the new sensor for the data logger on the "far side" of the original scale post. |
 |
Karen, John and Dorothy assist in installation of data logger in March, 2010. *Click on the picture to view a QTVR (4877) taken from just above the gauging station. |

|
The top of the sensor is where the LASCAR data logger is attached. A plastic bag and a metal cover is used for environmental protection. |
 |
The sensor was positioned so that the main lower band plus the next copper band was just at the low flow water level of 1 3/16 inch on the scale. |
 |
|
The Gov. Spring scale is marked in 1/16th inch increments. The water plants must be cleared for a clear reading. |
 |
The extra copper wire level sensor shown here to the right of the stainless band will check the effect of water and corrosion. |
 |
|
The actual data logger unit unplugs from the USB socket that connects to the leads. |
 |
The sensor, modified from the previous Snowy River installation, has bands to span an 8 inch range. |
