The man who captured the images, photographer Nigel Ogram, wanted to showcase the low water levels because he remembers what the lake was like the last time we had similar drought-like conditions in 1976.
Nigel said: "I've been visiting Lake Vyrnwy since I was very young - more than 50 years ago.
"I remember the low water levels in '76 and wanted to see it again."
"I'm a keen Vyrnwy photographer, but this time, I decided that aerial shots would show the low water levels more clearly," he explained.
And Nigel was right! The below images, captured on Saturday (August 13), really do clearly show just how low water levels have become in Lake Vyrnwy.
In the below photograph, you can see the top of the lake's straining tower. When water levels in the reservoir are normal, none of the 'gravel' at the top of the image is visible - it's covered by water.
The below photograph, taken at ground level, shows what the straining tower normally looks like, with the lake submerging almost everything around it.
It's a similar story with this lush, green bush, purportedly the size of a house and sitting in the middle of a parched island.
In the above image you can see the bush as it is now. In the below photograph, taken at ground level, you can see what it looks like when water levels are as they should be.
The reservoir would usually be nearly 90 per cent full in July-August, but it's now pretty much approaching half empty.
The old village of Llanwddyn, abandoned and submerged by the new dam in the late 1800s, has even re-emerged prompting a large number of visits by tourists and photographers.
Another photographer also took the time at the weekend to produce this stunning video, featuring both drone footage and beautiful still images of Lake Vyrnwy and the famous sunken village - Llanwddyn.
Steve Cort captured the below images and video at the weekend, also emphasising that the reservoir is "very very low at the moment!"
While heavy rainfall brings with it a unique set of problems, especially post heatwave, it's hoped pending wet weather will at least provide some respite for our parched reservoirs.
