Description: This data was derived as part of the Overall Assessment of the State of Nearshore Waters.Connectivity between watersheds and the nearshore supports healthy habitats and promotes natural physical processes. Barriers to connectivity can restrict access of fishes to spawning/nursery habitats and alter nutrient flows and coastal processes. Tributary connectivity is assessed by calculating the percent of the total length of tributaries flowing into a Regional Unit that are connected to the nearshore.Tributaries are a subset of the Ontario Integrated Hydro Network and have been assessed as either 'connected' 'naturally disconnected' or 'disconnected' from a Regional Unit.Connected:tributary is downstream of a barrier (e.g. dam) and hydrologically connected to the nearshore.Disconnected: tributary is upstream of a barrier (e.g. dam) and hydrologically disconnected from the nearshore.Naturally disconnected: tributary is upstream of a waterfallTributaries are dissolved by 'Status.'Low Stress: >75% of the total length of tributaries are connected to the Regional Unit: Moderate Stress: 25-75% of the total length of tributaries are connected to the Regional Unit; High Stress: <25% of the total length of tributaries are connected to the Regional Unit.This layer is a cartographic representation of the area of tributaries that drain into each Regional Unit.
