swamp/water/water_murky

An in-game screenshot of the water with the number 170. The number is pointing at the fog.

Bottom Material swamp/water/water_murky_beneath.vmt

The VMT includes the line "$basetexture" "swamp/water/water_murky". This base texture is 4 times larger than the normal-map texture, so the game scales up the normal-map accordingly. However, the Water shader does not actually render base textures, so the increased scale was most likely unintentional.
