Dome Creek at this point is fourth order. The residual in this case is everything outside sub-basins A, B, and C, but within the Dome Creek watershed. The totals for the entire watershed would be the sum of the four. Stream ordering technique. The entire watershed is a fourth-order watershed.
Most communities using surface water sources extract water from streams.
A large number, however, extract water from lakes. Information on how to determine where water system intakes are and how to determine water use is also included. The final decision on where to locate the POI should be made at the initial round table meeting. If there is more than one licensed community intake, the POI is established at the lowest intake on the system. If one or more individual water licences exist on the stream within 100 m downstream from the licensed community water intake, a decision may be made to move the POI downstream to provide protection for the individual licences.
