We woke to a VERY cold morning: maybe less than 4 degrees. I was up at 6.30 am in order to pack up and be away in time for a visit to Wellington Dam, where we were to meet up with our local guide, Alison. The great attraction are the murals all along the dam wall:

Works going on to construct a new bridge. Previously, cars could drive across the top of the dam wall. but it became too dangerous. |

I realised that JL must have been involved in the design and construction of this dam, so when I got home from the trip I searched in his memoirs. There was not a lot, as he had written much more about his first big project at Mundaring. He wrote:
During the years 1948 to 1951, I worked on many small town water supplies, bringing water to some 30 towns, which had never had a water supply before. In some cases the level of hygiene would not have been acceptable now and there was no environmental process to be followed.... Although we had a few scares with algae blooms and goldfish dying, we had no epidemics and people just needed to be careful.
Wellington, Harris Dams
In those years, a lot of time was taken on the raising of Wellington Dam. The hydraulics had to be established as well as design of the wall, which closely followed the example at Mundaring. As well as water supply to the south-eastern wheat belt, Wellington was to be used to extend the irrigation system to the coast. There was a known problem with increasing salinity on the catchment so we tried to limit that by restricting clearing on the catchment. This was politically very unpopular but some success was achieved.
The problem of supply of good water to the south-eastern wheatbelt was solved by putting a smaller dam on the Harris River, a virgin tributary from the highest rainfall part of the catchment north of the town of Collie.
When he talked of hygiene, I believe he was referring to the water supply. Nowadays, our water has chlorine and other chemicals added. In fact, my water at Burswood contains so much chlorine that I always set a jug of water by the sink to allow the chlorine to disperse before I use it for drinking and cooking.
This plaque remembers the artist responsible for the murals on the dam wall:
Near to the dam lookout, in what appears to be just waste ground, there were lots of wildflowers coming into bloom:

More of the Wedding Bush creeper |
There were also many interpretive boards, full of information - too much to take in! This snippet relates to the early days of the timber industry in these parts:
The group agenda at this point was onto the 3.5 km Sikh Trail, but I was feeling worn out after yesterday's walk. I decided to sit in the sun for a while before driving home at a leisurely pace.
