GIS Watershed Activity - Albemarle Watershed
Albemarle Watershed GIS Activity
Purpose: Students will learn about the management of a coastal fishery and the conservation career of fishery biologist, while using GIS (Geographic Information System) data to locate which watershed they live in and then determine which dams in their river’s watershed should have fish passage placed in them.
Duration: 45 minutes to one hour
Materials: (PDFs, external links)
- One foot-long piece of string for each student group.
- Attachment 1 - Be a Fisheries Biologist for a Day: Watershed GIS Activity (1 per student)
- Attachment 2 - American Shad profile (1 per student)
- Attachment 3 -Profile of a Biologist (1 per student)
- Map 1 Neuse and Albemarle Shad Spawning Watersheds (1 per group)
- Map 2 Shad Spawning Watersheds of the Albemarle Sound (1 per group)
- Map 3a Roanoke River Watershed above Roanoke Rapids Dam (1 per group)
- Map 3b Meherrin River Watershed above Emporia (1 per group)
- Map 3c Nottoway River Watershed above Camp Pickett Lake (1 per group)
- Give each student a copy Attachments 1, 2, 3
- Have each student read and the answer questions on Attachment 1.
- Break the students into small groups to do the Watershed GIS Activity.
- Hand out a set of watershed maps (Maps 1, 2, and 3a through 3c) and a piece of string to each group.
- Have students review the watershed maps in order, follow the Directions on how to work with their watershed maps and answer the questions on their student worksheets.
Computer Activity: Have students go to the U.S. Geological Survey WaterWatch website (external link). A map of the United States will appear with all of the river gauges in the U.S. that monitor river data. Students can click on North Carolina. They will be able to bring the cursor to each gauge and access the river conditions including flow in real time. They can then compare these current river flow rates to the flow rates that they calculated and answer the question:
- Q: Why are your numbers higher or lower now?
- A: Their numbers will be lower if there has been more rain in the watershed than the average rainfall and their numbers will be higher if there has been less rainfall than average.
