==Geography== The Dudidontu River originates near the headwaters of the [[Little Tahltan River]] and [[Egnell Creek]], in the [[Level Mountain Range]] on the [[Nahlin Plateau]].<ref name="DR">{{cite cgndb|id=JBBVA|title=Dudidontu River|access-date=2021-08-14}}</ref> From its source the river flows west in a [[U-shaped valley]] of [[Level Mountain]],<ref name="DR"/><ref>{{cite report|title=Caribou habitat use on the Level Mountain and Horseranch Ranges, British Columbia|last1=Fenger|first1=M.A.|last2=Eastman|first2=D.S.|last3=Clement|first3=C.J.|last4=Page|first4=R.E.|journal=Wildlife Working Report|publisher=[[British Columbia Ministry of Environment and Climate Change Strategy|Ministry of Environment and Parks]]|page=11|year=1986|issn=0831-4330}}</ref> then south, then by Ketchum Lake,<ref>{{BCGNIS|3792|Ketchum Lake}}</ref> where the Dudidontu turns and flows generally north for the rest of its length, about {{convert|112|km|mi|abbr=on}} in total.<ref name=length>Length measured using Google Maps path tool, BCGNIS coordinates, topographic maps, and [http://www.topoquest.com/ TopoQuest].</ref> It flows by Camp Island Lake and between Level Mountain and the [[Heart Peaks]].<ref>{{BCGNIS|10504|Camp Island Lake}}</ref> It is joined by its main tributary, [[Kakuchuya Creek]], and Kakuchuya Creek's main tributary [[Matsatu Creek]], both of which flow from Level Mountain.<ref>{{BCGNIS|2977|Kakuchuya Creek}}</ref><ref>{{BCGNIS|6476|Matsatu Creek}}</ref>
The middle Dudidontu River, from Camp Island Lake to {{convert|6.4|km|abbr=on}} below Kakuchuya Creek, meanders through a wide floodplain, providing excellent spawning habitat for [[Chinook salmon]]. Below this section the lower Dudidontu flows through a {{convert|19.2|km|abbr=on}} long canyon with steep slopes of mud, boulders, and shale, with no vegetation. This section of the river is a series of almost continuous heavy rapids.<ref>{{cite web |url= https://www.adfg.alaska.gov/fedaidpdfs/FREDF-9-9(18)AFS41-5.pdf |title= A Study of Chinook Salmon in Southeast Alaska |last= Kissner |first= Paul |publisher= Alaska Department of Fish and Game |pages= 20–21 |access-date= 12 August 2021}}</ref>
The Dudidontu River's watershed's [[land cover]] is classified as 37.9% [[shrubland]], 25.3% [[conifer|conifer forest]], 22.6% [[Barren vegetation|barren]], and small amounts of other cover.<ref name=watertool/>
