Vertical Patterns in Lake Sturgeon (Acipenser fulvescens) Larval Drift within Two Rivers Directly Connected to Green Bay, Lake Michigan

Figure 1

Map of the Menominee and Oconto Rivers (Wisconsin, USA) showing their proximity and confluence with Green Bay, Lake Michigan. Circles in the left panel show the approximate sampling locations for netting recently emerged and drifting larval lake sturgeon in the spring of 2013. The upper right panel shows the Menominee River sampling transect which is approximately 200 meters wide and where water depth required nets to be deployed by boat (left is upstream). The lower left panel is the Oconto River transect where the channel is approximately 25 meters wide with a wadable water depth (top of picture is downstream).
