What is a Watershed?
By Deshawnna Exilus and Nicole Aguilera
A watershed is the area of land where all water running off the land drains to a particular location. This location can be a stream, river, lake, wetland or ocean. No matter where you live, work, or play, you are in a watershed. A watershed can be millions of square miles (like the watershed for the Mississippi River) to a few acres (like the watershed of a farm pond).

How to determine if your watershed is healthy
- Check the water color.The quality of the water has a big impact on the health of stream.
- Check the stream temperature.The temperature of the stream changes throughout the year because of the seasons.
- Check the riffles in the stream.
- Check the steam bank erosion.Steam Bank Erosion is when the sides of a running streams collide into the moving water below.
- Check the Fish Shelter.Trees hanging over 50% of the stream provide good habitat for fish but less than 50% is a fair or poor habitat.
- Check the algae color because hairy algae means that you have poor water quality.
- Check the foam.Foam in a stream can be natural or human caused.
