river in northern Shandong
漯 is a rare kanji used primarily as a proper noun for a river in northern Shandong. Its standalone meaning is tied to that specific geographical name.
漯 combines 氵 (water) with 累, which likely provides the sound. It is a phono-semantic compound used for a river name.
The water radical 氵 beside 累 suggests a river. Picture the accumulated (累) waters of a specific river in Shandong.
For トウ, imagine a tall tower (タワー -> トウ) standing beside the river: the tower's name echoes the reading トウ.
