The Stage in SWR: Surface-Water Routing Process pane is on the MODFLOW Features tab of the Object Properties dialog box.

Starting time and Ending time are explained in the help for the MODFLOW Features tab.

SWR Stage (STAGE2D): STAGE2D defineS the stage for each reach in model grid cell (in units of length). On the first stress period, STAGE2D represents initial stages for the surface-water system. For subsequent stress periods, STAGE2D is used to change the stage in constant-stage reaches (ISWRBND < 0) and/or reach offsets for reaches using the tilted-pool reservoir-routing approximation(IROUTETYPE = 2) to simulate surface-water flow.
