Overview

Active WGCMA Estuary Management Group

Merriman Creek is a small creek estuary, flowing from the Strzelecki Ranges through intensive grazing and plantation forestry areas, before flowing to Bass Strait adjacent to the township of Seaspray. Merriman Creek is a source of potable water supply. The estuary is a popular location for recreational activities and fishing and provides a diversity of habitat for birdlife and fish. The area has important Aboriginal cultural heritage values for the Gunaikurnai people.

Merriman Creek, Mouth Observation Site
Active Mouth Condition 18-09-2020 - 17-12-2024

Merriman Creek flows out into the surf beach. Due to the intensity of the wave action, the creek can be 'pushed' via longshore drift further up along the beach due to the intensity of the wave action. This can then threaten built assets such as the ramp access onto the beach from the surf beach and beach access boardwalks. 

The site is popular with fishermen, kayakers and surfers a like. There has been concerns in the past of flooding, and some anecdotal evidence of concerned residents 'opening' the estuary themselves. Currently there is a height gauge and the site has active telemetry of stream height organised by the Wellington Shire.

Merriman Creek, Photopoint
Active Photopoint 09-11-2020 - 20-01-2025

Merriman Creek Estuary is a wave dominated estuary. Due to its location in a rain shadow it does not receive regular inundations but is known to close. Anecdotal evidence suggests concerned residents will open the estuary themselves if they see fit. 

A popular site for fishermen, surfers and kayakers alike.
