Went to Lake Linsenholz which is a construction site at the moment. It's very muddy around the lake, we sunk in a bunch of times. My camera did an extraordinary bad job at focusing today. So I apologize for the crap quality. 2: info sign with tons of typos, 4: rest of drain (MΓΆnch), 5: old rainwater channel across the forest path, 8-10: surprisingly, they used wooden veneers to protect seedlings against being eaten, I only ever saw plastic stuff which breaks down in the sun in a few years and leaves a big mess, 12: counter contruction site by a mole, 18: extracted drain, 19: Lyse sinking in the sand (it kinda looked like solid gravel).

Empty lake

@prologic Yes, it's this one lake that had been emptied two years ago to fix some problem with the drain structure. Apparently, they didn't do a well enough job, there's an issue with the drain tower again. This time, though, they want to get rid of it entirely, rebuild the dam and create a spillway instead.

Took me like half an hour to find a photo from July 2021 were the lake was actually operational (I reckon I should start tagging my photos). In the middle left you can see the top of the drain structure. It's basically a big pipe that allows water to run out of the lake into the other other side of the dam. With a mechanism of movable damming boards you can regulate the level of the lake:

From the draining phase in October 2023, the lake looked like that. Pretty much emptied lake from the same point of view:

Still standing drain tower to be removed:

@prologic Not entirely sure, but I guess so.
