The pollution level of the lagoon is very high in the Lagos harbor segment and decreases in the Metropolitan end of the lagoon, while the Epe segment is a bit free as it has the least level of pollution.

There is a difference in the salinity of the lagoon due to the effect of the Atlantic ocean and it fluctuates seasonal and semi-diurnally. These fluctuations are greatest in the Lagos harbor segment of the lagoon because of the influx of water from the Atlantic ocean and the lagoon.

The bottom has coarse Shelly sand around the mouth of Lagos harbor through the different grades of muddy sand to mud. The Sandy mud deposit happens in the middle areas with muddy sand of the sands that are towards the shore.
