Illustration of subsurface-drained agricultural field
A hypothetical configuration of one of the two drained field sites, including a weather station for measuring climate data, a piezometer network for continuous water level measurements, soil moisture probes, and subsurface drainage flow. The third undrained field site will have a similar configuration, with the absence of subsurface drainage flow.

Grass carp larvae
These images show grass carp larvae from the Maumee River. Characteristics of larval grass carp include overall length (left), skeletal muscle development (center) and presence of an eye spot that lacks pigmentation (right; pigment starting to develop on lower eye).
