Top photos you pulled look like Naiad to me. Lot of dead material makes it a bit tougher to id.
Bottom look like good ol cattails. Bulrush has rounded stems, tassles on top, no flat leaves. Emergent cattails, no catkins, yet. Photos very good. A few cattails normal, but without control they can take over an entire pond. 360 of shoreline. Do yourself a favor and practice preventive instead of corrective maintenance.
