B7 Reedy Lake Gate South Side

Active Physico-Chemical 06-02-2017 - 25-05-2018

The Reedy Lake Gate South Side monitoring site has been added to the Barwon EstuaryWatch Monitoring Plan to provide ongoing water quality data to assist in the management of the watering regime for Reedy Lake. Water flow between the lake and the wider Barwon estuary can be controlled via gated access points. This monitoring site is located at the Reedy Lake outlet gate, that is, where water from Reedy Lake flows out through the gate when it is lowered.

This site is only monitored by EstuaryWatch volunteers when accompanied by an EstuaryWatch Coordinator. It is a physical/chemical monitoring site, but photopoint monitoring will also be undertaken in an effort to track vegetation change aligned with changes in the water regime.

B8 Reedy Lake Gate North Side

Active Physico-Chemical 06-02-2017 - 15-03-2017

The Reedy Lake Gate North Side monitoring site has been added to the Barwon EstuaryWatch Monitoring Plan to provide ongoing water quality data to assist in the management of the watering regime for Reedy Lake. Water flow between the lake and the wider Barwon estuary can be controlled via gated access points. This monitoring site is located at the Reedy Lake outlet gate, that is, where water from Reedy Lake flows out through the gate when it is lowered.

This site is only monitored by EstuaryWatch volunteers when accompanied by an EstuaryWatch Coordinator. It is a physical/chemical monitoring site, but photopoint monitoring will also be undertaken in an effort to track vegetation change aligned with changes in the water regime.

B9 Fitzgeralds Road Boat Ramp

Active Physico-Chemical 06-02-2017 - 25-05-2018

The monitoring site is located at an unstructured boat ramp which is adjacent to a 5 Knot sign. As water levels in Reedy Lake alter, monitors will need to adjust where they stand on the boat ramp to monitor the water safely.

This site is only monitored by EstuaryWatch volunteers when accompanied by an EstuaryWatch Coordinator. It is a physical/chemical monitoring site, but photopoint monitoring will also be undertaken in an effort to track vegetation change aligned with changes in the water regime.
