This same Hezekiah also stopped up the upper outlet of the waters of Gihon and channeled them down to the west side of the City of David. Hezekiah succeeded in everything that he did.

After this he built an outer wall for the City of David on the west side of Gihon, in the river valley, to the entrance of the Fish Gate; and he encircled the Ophel with it and made it very high. Then he put military commanders in all the fortified cities of Judah.
