You're concerned with dams that block the main branch and tributaries (smaller streams that feed into the main branch of the river). The map is saved to My Content, which you can access from the content page. Use imagery to determine which dam is most suitable for a new fishway. Estimate the total amount of spawning habitat made available by the fishway construction. The search distance parameter specifies the distance from the point that the tool will search to find the largest drainage line.

This layer is not necessary for future analysis, so you will remove it. However, Atlantic salmon have a different biology and are more likely to return to the same river to spawn again the following year. Now that you've added the hydrology layer and filtered the data to extract the habitat that is most suitable for salmon spawning, you'll summarize the amount of habitat made available with the construction of a fishway. To show features that best represent this habitat, you'll filter the Mersey Hydrology layer. In many locations, the imagery will allow you to determine if a dam was constructed with a fishway.

You used analysis tools to create upstream watershed areas from river barriers, determined the area that salmon could potentially access via a new fishway, and calculated the amount of habitat available within this area. Title: Now, you'll estimate the amount of salmon spawning habitat that would be made accessible by the proposed fishway. This map was created to assess candidate dams for fishway construction in the Mersey River, Nova Scotia, Canada. Atlantic salmon are over-fished and salmon farming is fraught with environmental costs. In this lesson, as a GIS technician, you'll identify the best locations for constructing these aquatic bypasses. Some fish spend their lives in both fresh water and salt water.

From the current extent, aquatic connectivity along the Mersey River is troubling. While more study needs to be done to confirm the findings, the research appears to prove the theory that the “magnetoreceptors” in salmon play a critical role in their migration. Salmon that migrate into the rivers and creeks of the Bay Area trickle down both from the north (Tomales Bay) and work their way up from the south (Santa Barbara) of California. Now that you've determined the total amount of habitat made available, you'll label this in your map.
