Excursion to Eganstown and Basalt/Werona area

Eleven members joined the September excursion which began at St Georges Lake, Creswick. It was cool with a chilly wind as we walked down the new pathway to inspect the big engineering changes at the spillway.

An impressive amount of rock and the excavation of 20,000 cubic metres of soil has produced a new spillway to replace the old compacted earth wall. According to the Parks Victoria’s website, the new wall removes the risk of the old wall failing during future heavy storm events. The ability to walk over the new dam wall is retained so visitors may still complete a circuit of the lake if they wish.

It was a surprise to those of us who had not been to the site for a while, to see the new dam wall extent of the works. Combined with the harvesting of the plantations, the works have made a major change to the site. The design of new dam wall means less water in the lake than previously so that even in high rain events, the water will flow more slowly. It is about 2 metres lower.

There have been a few other works to the picnic ground such as new fencing to prevent vehicles driving right up to the water edge. There jetty like structure at the other end of the lake is now closed off and about to be demolished as it is in such poor condition with trees growing through it. It will also no longer be in the water due to less water held in the lake. Before we left, we began the wattle count for the day with some local and planted wattles.

The next stop was the Newlyn Reservoir, which is located on Birch’s Creek. Water is used for irrigation, domestic and stock supplies and some urban use. We made a small list of water birds observed but we did not linger, as it was still a cool wind blowing off the water.

Pump house Deep Springs

Deep Creek Streamside Reserve at Eganstown was the morning tea stop with bright sunshine with no wind. A grey mistletoe, Amyema quandang in a silver wattle, provided some discussion and the cameras came out.

There was also a close examination of the root system of a eucalypt exposed when the tree blew over in a storm. As we walked down the path to the spring, we heard quite a few birds as they flew in and around the silver wattles and eucalypts.

Access over the bridge to the pump house is closed, so after a brief look around including looking if the swallows were nesting under the bridge, we went back up the hill to the vehicles.

We continued the excursion by taking the Werona Road, which is off Basalt Road. This road winds through pine plantations but we did stop at an area where the replanted pines were only small to enjoy the views across to the ‘lollipop’ on Mt Beckworth, the Waubra wind towers and Mt Kooroocheang (known also as Smeaton Hill).

Earth Tongue

Earth Tongue – Trichoglossum hirsutum

Driving to the next stop, we had glimpses of Mt Franklin while passing through more young pines. The sides of the road were colonised by Cassinia arcuata, Chinese Scrub. Eventually we were back in the bush and noticed that the vegetation had changed to survive a drier aspect. There was a quick sighting of Acacia pycnantha, Golden wattle. At this stop, earth tongues were the main interest. These fungi are like short thin narrow tongues poking up out of the earth and are black.

The lunch spot was near a dam so there chance of seeing some birds but only a fan-tailed cuckoo came close. We did not see the wedge tailed eagle that Bill and Paul had observed take flight when they were checking out the site in the previous week so we settled for some interesting plants. At our last stop in the bush, we added Acacia gunnii, Ploughshare wattle to the list.

Bridge near Kingston

Finally heading home, we stopped to admire a bridge built in 1883. Many people who travel on the Kingston Kooroocheang Road probably have never given this bridge much thought. The creek is choked with willows but a gap in the blackberry allows a photo of the bridge, which looks in good condition. It would be great for a group to take over the management of this site.
