This has resulted in a decline in the abundance and distribution of native freshwater fish across\r\nthe entire valley. The Department of Primary Industries and Regional Development (Fisheries) was engaged by\r\nthe NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW), Biodiversity,\r\nConservation and Science (BCS) Group to conduct baseline fish community sampling in the Lower Gwydir\r\ncatchment, as part of the Gwydir Reconnecting Watercourse Country Program (Gwydir RWC Program). The\r\nmain objective of the project was to collect baseline data on fish communities in the three RWC Program areas\r\nto provide information on the current state of the fish community and to assist in evaluating the effectiveness\r\nof the Gwydir RWC Program intervention measures in the future, which are proposed to include improving\r\nenvironmental water delivery through designated flow corridors and the removal or modification of physical\r\nconstraints to improve flows to wetlands. Nineteen sites were sampled (or visited) between May and October\r\n2024, within three areas across the lower Gwydir Valley; Lower Gwydir River (n = 5), Lower Mehi River (n = 6)\r\nand Gingham Watercourse (n = 8). In total 297 fish were caught (n = 295) or observed (n = 2) which included six\r\nnative and three exotic species. The exotic species common carp (Cyprinius carpio) had the highest abundance,\r\nand the highest overall biomass of the fish sampled. Of the thirteen native species \u201cexpected\u201d to occur, eight\r\nwere not captured but, six of these are considered \u201crare\u201d or \u201coccasional\u201d and as such there was only a low\r\nexpectancy of them being caught. However, several more \u201ccommon\u201d species were also not sampled or were in\r\nextremely low numbers including Murray cod, freshwater catfish, carp gudgeon and Murray-Darling\r\nrainbowfish. Restoring the fish communities across the lower Gwydir and its associated tributaries will be a\r\nlong journey requiring willingness and participation across all levels of government and society alike.\r\nReturning consistent water to the wetlands in the Gwydir and Gingham systems for longer periods and\r\nreconnecting the Gwydir system to the wider Barwon-Darling via regular whole of system connectivity along\r\nthe entire lower Mehi will have both immediate and long-term benefits for fish.", "num_resources": 2, "num_tags": 3, "organization": {"id": "139dd472-a9c0-4063-8de9-3b9b5ff5f255", "name": "nsw-department-of-climate-change-energy-the-environment-and-water", "title": "NSW Department of Climate Change, Energy, the Environment and Water", "type": "organization", "description": "Ensuring a sustainable NSW through climate change and energy action, water management, environment and heritage conservation and protection.", "image_url": "2024-02-06-050442.862891imageupload", "created": "2024-02-06T16:04:42.881176", "is_organization": true, "approval_status": "approved", "state": "active"}, "owner_org": "139dd472-a9c0-4063-8de9-3b9b5ff5f255", "private": false, "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[148.76724, -29.60622], [148.76724, -29.20904], [149.7615, -29.20904], [149.7615, -29.60622], [148.76724, -29.60622]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[148.76724, -29.60622], [148.76724, -29.20904], [149.7615, -29.20904], [149.7615, -29.60622], [148.76724, -29.60622]]]}", "state": "active", "temporal_coverage_from": "2024-05-26", "temporal_coverage_to": "2024-10-10", "title": "Fish Community Baseline Monitoring in the Gingham Watercourse, Lower Gwydir River and Lower Mehi River 2024", "type": "dataset", "unpublished": "false", "update_freq": "notPlanned", "url": null, "version": null, "extras": [{"key": "harvest_portal", "value": "SEED"}, {"key": "harvest_url", "value": "https://datasets.seed.nsw.gov.au/dataset/gwydir-fish-community-baseline-monitoring-2024"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-23T00:44:51.592074", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "format": "PDF", "hash": "", "id": "199f8945-1089-41f7-b583-4dc9b53f7d18", "last_modified": null, "metadata_modified": "2025-10-23T00:44:51.527263", "mimetype": null, "mimetype_inner": null, "name": "Data Quality Statement", "package_id": "e0105f9b-6455-4a75-90c6-8ab80ac4c7ee", "position": 0, "resource_type": null, "size": null, "state": "active", "tracking_summary": {"total": 0, "recent": 0}, "url": "https://datasets.seed.nsw.gov.au/dataset/gwydir-fish-community-baseline-monitoring-2024/resource/data_quality_report/pdf", "url_type": null}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-23T00:44:51.592078", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "format": "PDF", "hash": "", "id": "6260dd64-a617-46c8-8de3-bcfc1234248f", "last_modified": null, "metadata_modified": "2025-10-23T00:44:51.527535", "mimetype": "application/pdf", "mimetype_inner": null, "name": "Gwydir Fish Baseline Monitoring Report 2024", "package_id": "e0105f9b-6455-4a75-90c6-8ab80ac4c7ee", "position": 1, "resource_type": null, "size": null, "state": "active", "tracking_summary": {"total": 0, "recent": 0}, "url": "https://datasets.seed.nsw.gov.au/dataset/7520b9b9-c8c4-4a48-8793-32968994eec2/resource/f475831c-752b-4828-92f3-1d5d4a4b371f/download/nbtk_grwc_fishbaselinemonitoring2024.pdf", "url_type": null}], "tags": [{"display_name": "Baseline survey", "id": "fe0404c3-bace-43fe-8c1a-2bb1f3c7156c", "name": "Baseline survey", "state": "active", "vocabulary_id": null}, {"display_name": "Fish Community", "id": "c05fe937-64d8-4804-80b8-25a17d1ff91b", "name": "Fish Community", "state": "active", "vocabulary_id": null}, {"display_name": "Gwydir wetlands", "id": "4259fb7c-c07e-441f-a37a-be2c59976911", "name": "Gwydir wetlands", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "likes": 0, "tracking_summary": {"total": 0, "recent": 0}}}
