. w M J J A S Month O N D Figure 22. Seasonal abundance of the dominant macrozooplankton at the Mid-Lake North and Mid-Lake Deep stations in Flathead Lake during 1988. Densities at MLD were calculated by summing up incremental 10m hauls from 50m to the surface. Densities at MLN were calculated from 50m to surface hauls from January-June and November, and on the other dates by summing up incremental hauls from 50m to the thermocline and from the thermocline to the surface.
