Its flow through the Tulsa area is controlled by upstream [[Keystone Lake|flood control reservoirs]], but its width and depth can vary widely throughout the year, such as during periods of high rainfall or severe drought. A low-water dam was built to maintain a full channel at all times in the area adjacent to downtown Tulsa. This portion of the river was known as Zink Lake. However, the City of Tulsa allowed the dam to deteriorate and it no longer functions to retain the lake for which it was designed.<ref>{{Cite web|url=http://cdm15020.contentdm.oclc.org/cdm/ref/collection/p16063coll1/id/1681|title=Low-water dam lake to honor Zinks|website=Cdm15020.contentdm.oclo.org|access-date=May 8, 2021|archive-date=October 29, 2014|archive-url=https://web.archive.org/web/20141029183158/http://cdm15020.contentdm.oclc.org/cdm/ref/collection/p16063coll1/id/1681|url-status=dead}}</ref><ref>{{cite news |first=Gretchen |last=Collins |title=River Parks Proves Practical Need for Visionary Ideas |work=Urban Tulsa Weekly |url=http://archives.urbantulsa.com/article.asp?id=11 |access-date=April 30, 2007 |archive-url=https://web.archive.org/web/20070928063005/http://archives.urbantulsa.com/article.asp?id=11 |archive-date=September 28, 2007|url-status=dead}}</ref> Heavily wooded and with abundant parks and water areas, the city has several prominent hills, such as "Shadow Mountain" and "[[Turkey Mountain Urban Wilderness Area|Turkey Mountain]]", which create varied terrain, especially in its southern portions.
