Challenge #1 Hints

To help you solve the puzzle of Challenge #1, we will be sharing helpful suggestions site specific hints throughout the next 3 weeks.  Keep an eye out for emails from Asher to keep you informed of when new hints are added to the site.  

General Hints

Below is a few webites that you may find helpful when viewing water quality data for the Red River.  
*** If you have not read through the introduction presentation – make sure to start there ***

1

Mapping Portal

The IWI mapping portal allows users to view subwatershed boundaries, lidar data, and access a variety of tools.  Lidar data allows us to view elevation change accross the surface of the earth. 

2

Watershed Pollutant Load Monitoring

This monitoring network collects pollutant data from rivers across the state of Minnesota. 

3

Stream Stats

Stream Stats has some similar tools to the mapping portal, though it does not have a lidar layer. The site does incoporate gauging sites and allows you to create elevation cross sections and create flow paths. 

Week #1 Hints for Challenge #1

Hint #1 – 
Did you know Google Earth lets you view previous satellite imagery? Site RR-320 had a bridge replacement project from 2009-2011.
 – If you do not have access to Google Earth, explore the base layers in the IWI Map Portal – 

Hint #2 –
The TSS concentration at Point K is 67.6 units lower than the site with the highest TSS concentration.

Hint #3 – 
The riparian area of the river is great wildlife habitat – in fact, you might see a “bird” near Site RR-589.

Hint #4 – 
Site 996 is located to the east of a town that is the 11355th most common last name in the US.

Week #2 Hints for Challenge #1

Hints #5 – 
Data from site 220(228) was collected at a site where an oxbow lake is formed when the river morphs a new path and cuts off a section of a meander. This site could also be a great place to find a “birdie.”

Hint #6 – 
Site G’s TP value is the same forward as it is backward.

Hint #7 – 
Data from RR-423 was collected from a bridge just downstream from a monument that is named after an amphibian.

Hint #8 – A majority of the lab parameters collected at point F were the highest of the lab data collected at any of the sites.

Week #3 Hints for Challenge #1

Hint #9 – Point E on the map is home to a site whose name is numerical order.

Hint #10 – Point L’s total phosphorus value is 6th highest of all values.
