The outdoor stream lab is flooded now. There are several people out there taking different readings of things like velocity, depths, phosphorus levels, and others.

This is what is going on outside.

I am the assistant photographer.

But mainly I am doing the background readings on my topic of the endangered Topeka shiner and the impacts of barriers in their passage. The barriers in our study are culverts which can be made of corrugated metal tubes or concrete barrels . This is a photo of a double barrel culvert at the first site we visited.
