WIP: Part 50's BTS (Patreon)

Still work in progress, sorry for the delay. Here's few you haven't seen yet, though!

Tuusulanjärvi is a beautiful lake, although nowadays it's really eutrophic because the surrounding farmers directed all their fields' waste water to the nearby creeks, which then flowed to Tuusulanjärvi.

Nowadays the surrounding towns, Järvenpää and Tuusula, have made huge investments to clean out the lake again, but its brownish-green colour still remains when observed from above.
