Target Reference Point

One of our U2 spy planes spotted Spectre units around the area surrounding these lakes. However we lost location metadata while collecting huge amounts of imagery. Can you help us find the name of the lake marked by the target reference point ‘+’ symbol? https://satellites.pro/ might be useful to compare a variety of imagery sources. Attached: geoint.png

This is the obligatory Level 1 OSINT challenge. We are given the following image and asked to find the name of the lake.

Notice the compass at the bottom-right corner of the image. By rotating the image so that it is in the correct orientation, reverse image search yields a similar image from the paper “Waterbird Population Dynamics in the Middle Mahakam Wetlands of East Kalimantan over 23 years”.

There were a few red herrings in this challenge. One, the map’s scale bar suggests that we could try estimating the area of the lake. Two, the challenge description mentions “https://satellites.pro/ might be useful to compare a variety of imagery sources”. Neither path was actually necessary.
