The Susitna River and the Yentna River meet in a landscape of complex waterways and wetlands in this portion of the Matanuska-Susitna Borough. This 2023 survey illustrates the dynamic hydrology of the region, where the broad Kroto Slough meanders through the lowland terrain. The presence of remote aviation infrastructure, such as the Poker Bluff Airport and CTS Airport, highlights the essential role of air travel in navigating this roadless Alaskan interior. Isolated water bodies like Witsoe Lake and the winding course of Fish Creek further characterize the area's intricate drainage patterns, providing a detailed look at the environment just upstream from the Cook Inlet confluence.
