Sept. 27, 2012, Silver Lake, Brighton, Utah, approx. 8,720 ft. elev.The lush plant growth in these calm, shallow lake waters consists of a number of things but here primarily is Carex utriculata (Northwest Territory Sedge, and Beaded - not Beaked - sedge are some of its common names). C. utriculata has historically been treated by some authors within C. rostrata (Beaked sedge) but these are now somewhat more recently considered to be separate species and following those treatments, C. rostratra does not occur in Utah.
