Glimpse Lake is located in the forest just above the grasslands on the Douglas Plateau.       There are large areas of shallow water in the lake and aquatic plants grow and then flower in summer.

Bladderwort (Utricularia macrorhiza) is a floating aquatic perennial that produces yellow flowers on erect stems.   

The bladders which give common bladderwort its name are used to trap and consume prey.^[3] Small organisms trigger the hairs on the pores of the bladder as they brush against it, causing the pore to open inward, allowing a rush of water into the bladder which pulls the prey in as well.^[3] The pore immediately closes behind the prey, which is then digested by enzymes within the bladder.^[3] The process of trapping the prey from opening to closing the pore takes place in 0.002 seconds.^[3] If large prey becomes stuck in the pore, the prey is digested by the enzymes bit by bit until the pore closes again.^[3]

In shallow bays Arumleaf arrowhead (Sagittaria cuneata) was in flower with the male flowers above the female flowers.   It grows from a tuber and the arrow-shaped leaves float on the water.    There were also bays full of Mare’s tail (Hippuris vulgaris) or Smartweed (Persicaria amphibia).    All photos taken by the author from the kayak.    Click an image for a caption and a lightbox view.
