 Data Explore 1: Musselshell Up to Downstream

1. Select the “Musselshell River”

2. Select “boxplot”

3. What is the pattern in specific conductance moving from left to right across the plot? Why do you think this pattern exists?

Data Explore 2: Madison Arsenic

1. Navigate to data for the Madison watershed.

2. Which site has the highest arsenic?

3. How many sites have arsenic above the drinking water standard?

4. Why do some sites have high arsenic in the Madison?

Data Explore 3: Sun River Nutrients

1. Navigate to data for the Sun River.

2. What site has the highest nitrate concentration (easiest to see with boxplot).

3. What is the relationship between nitrate and total nitrogen (use the regression plot to see this)? What does this mean about the dominant form of nitrogen in the Sun?

Data Explore 4: Deep Creek Flows

1. Navigate to data for Deep Creek.

2. Use the dropdowns to select data by site
