    Notes The sky was bright blue with no clouds visible by the time we were counting the lower section. The air was still cool to cold. We noted that there was a deep scour of silt under the Thesens bridge when we passed there, a good sign, which will allow bigger fish in and out of the estuary. The silt banks were exposed and visible from the 2nd bend to the mouth of the estuary with the water flowing out quite fast. The mouth of the estuary is permanently open until September for the winter rainfall period to let the runoff water from the catchment out to sea and to prevent flooding of low lying infrastructure. Note - the southern section of the Marina canals were not counted today.
