The Gowanus Canal and Newtown Creek are industrial waterways in New York City. Both are heavily polluted, and both were formerly parts of tidal salt marshes. Centuries of development have altered everything about the landscapes of Newtown and Gowanus. They're edged with bulkheads instead of reeds, their tributaries are now sewers, and the mill ponds, copper plants, and coal works are long gone. The tides persist, an ever-present daily pattern of shifting water levels, driving invisible flows in the water tables around the canal and creek. Inspired by @riverthames, these twitter bots speak in the first person, cajoling you to come see the tide, to look carefully and closely.
The twittering waterways' knowledge is drawn from NOAA tide tables.
Run, don't walk! I have a low tide in 7 minutes. I'll be 23 inches shallower than average.— Gowanus Canal (@therealgowanus) April 27, 2015
Come by in 15 minutes and see my low tide, I'll be 24 inches below my average level.— Newtown Creek (@newtown_creek) April 27, 2015
