The most population was seen in diatoms (25583 cells/lit), dinoflagellates (687 cells/lit) and blue green algae (75 cells/lit), respectively.
The highest record of diatoms was seen in winter (66922 cells/lit), but blue green algae were dominated in summer (157 cells/lit).
The highest population of phytoplankton was seen in during June in surface water of eastern creek (156660 cells/lit).
In statistical study, difference between stations of two branches of creek (east branch and west branch) wasn't significant.
