For example, Dataplex Administrator\n (`roles/dataplex.admin`) or Dataplex Editor `roles/dataplex.editor`\n IAM role.\n\n- To delete a lake, you must be granted IAM role that contains the\n `dataplex.lakes.delete` permission. For example, Dataplex Administrator\n (`roles/dataplex.admin`) or Dataplex Editor (`roles/dataplex.editor`)\n IAM role.\n\nYou can also grant update and delete permissions to users or groups\nby using the `roles/owner` and `roles/editor` legacy roles.\n\nFor more information, see\n[Dataplex Universal Catalog access control with IAM](/dataplex/docs/iam-and-access-control).\n\nView a lake\n-----------\n\nTo view your Dataplex Universal Catalog lake in the Google Cloud console, follow these\nsteps:\n\n1. Go to the Dataplex Universal Catalog page.\n\n [Go to Dataplex Universal Catalog](https://console.cloud.google.com/dataplex/lakes)\n2. Click the name of the lake you want to view.\n\n3. Optional: To manage existing data zones in your lake or to add new data zones,\n click the **Zones** tab. For more information, see\n [Managing a zone](/dataplex/docs/manage-zone).\n\n4. Optional: to view lake details, such as the number of data items discovered,\n and the assets in the lake, click the **Details** tab.\n\n5. Optional: To manage lake permissions, click the **Permissions** tab.\n For more information, see [Access control with IAM](/dataplex/docs/iam-and-access-control).\n\n6. Optional: To view lake-level actions, specifically, issues around\n security policy propagation., click the **Actions** tab.\n\n View lake-level actions, specifically issues around security policy\n propagation. For more information, see [Discover data](/dataplex/docs/discover-data#other_actions).\n\nUpdate a lake\n-------------\n\nOnly one update job is supported at a time, and each job can have multiple\nproperty updates. You can still use the lake while it's being updated.\n\nYou can update the following lake parameters:\n\n- Name\n- Description\n- Labels\n\n| **Note:** You must recreate a lake if you want to change lake details that can't be updated.\n\nTo update a lake, follow these steps: \n\n### Console\n\n1. In the Google Cloud console, go to the Dataplex Universal Catalog page.\n\n [Go to Dataplex Universal Catalog](https://console.cloud.google.com/dataplex/lakes)\n2. On the **Dataplex Universal Catalog** page, click the lake name of the lake\n you want to update. The lake page for that lake opens.\n\n3. Click **Edit** . The **Edit Lake** page opens.\n\n4. Choose the updated lake parameter values.\n\n5. Click the **Save** button to update the lake.\n\n6. Verify that you have returned to the **Dataplex Universal Catalog** page, and\n that your updated lake appears in the list.\n\n### REST\n\nTo update a lake, use the [lakes.patch](/dataplex/docs/reference/rest/v1/projects.locations.lakes/patch)\nmethod.\n\nWhen the update succeeds, the lake automatically enters active state. If it\nfails, then the lake is rolled back to its previous healthy state.\n\nDelete a lake\n-------------\n\nYou might want to delete your lake if your configurations are wrong and can't\nbe changed.\n\nYou can't delete a lake until all data zone resources under it have been deleted.\nSimilarly, you can't delete a data zone until all asset resources under it\nhave been deleted. Users given access to data through these lakes or data zones\nlose access rights.\n| **Note:** When you delete a lake, your Cloud Storage buckets or BigQuery datasets aren't deleted. You must explicitly delete them if required.\n**Caution:** Deletion is irreversible. After you delete lakes, you can't restore them. However, you can create new Dataplex Universal Catalog lakes. \n\n### Console\n\n1. In the Google Cloud console, go to the Dataplex Universal Catalog page:\n\n [Go to Dataplex Universal Catalog](https://console.cloud.google.com/dataplex/lakes)\n2. On the **Dataplex Universal Catalog** page, click the lake name of the lake\n you'd like to delete. The lake page for that lake opens.\n\n3. Click **Delete** . The **Delete lake** dialog opens.\n\n4. To confirm the deletion, enter `delete`.\n\n5. Click **Delete Lake**.\n\n6. Verify that you have returned to the **Dataplex Universal Catalog** page, and\n that your deleted lake no longer appears in the list.\n\n### REST\n\nTo delete a lake, use the [lakes.delete](/dataplex/docs/reference/rest/v1/projects.locations.lakes/delete)\nmethod.\n\nDeletion might take some time to complete.\n\nWhat's next\n-----------\n\n- Learn how to [manage a zone](/dataplex/docs/manage-zone).\n- Learn how to [manage and attach buckets](/dataplex/docs/manage-buckets).\n- Learn more about [Cloud Audit Logs](/dataplex/docs/audit-logging)."]]
