The ecological condition of the lake basin is, in general, satisfactory – water is mostly of grades I and II (clean), and is of grade III in some rivers due to the high content of phosphorus.
The water condition of the rivers has improved since 2001–2007, but there is an increase in population of blue-green algae.
The main problem of Lake Peipus is its eutrophication.
