So, I decided to add to my water garden and built a new pond:
Top of the current pond (250 gallons, 10 foot stream)
The hole - it doesn't look like much
some size comparison with tools:
Size with my 7 year old:
And now the puppy joins him:
With the liner, doesn't look like much again:
Even from this angle:
Looking a bit more like a pond:
8.5' x 8.5' x 3.5 ':
