Generate ONLY a vertical waterfall structure based on the photo. STRICT SIZE LIMITS: Maximum height: 45 blocks. Maximum width: 9 blocks. Maximum depth: 6 blocks. This is a Minecraft survival-scale build. No cliffs, no mountains, no terrain. ONLY the waterfall column. If the build exceeds 50 blocks in height, it is incorrect.
