Both entrances to this culvert are hidden by a dense wooded area and I found it by accident one day, then I returned another day to explore with my brother. I have tried to find historical background to the reservoirs in this area but there is nothing on the internet. If anyone knows anything about it I would love to hear what they have to say. I can't find any evidence of other people visiting here either which makes me think that I dreamed the whole thing..... except I have these photos.
