This table shows the current status of any given structure based on key attributes. The team at ATS has developed a clever algorithm that automates this process.
| Current Status | Description | Next Steps |
| 0 – Not assessed | Generated from desk-top – not verified | Field assessment |
| 0.1 – Crossing with no structure | Site visited – no structure present – no barrier | Saved for future reference |
| 1 – Structure present but not currently a barrier | All fish passage at most flows. Can also be tidal. Can include single span bridges | Monitored |
| 1.1 – Probably not a barrier | On-site call by field tech. Usually determined as not a barrier. | Monitored |
| 1.2 – Unlikely barrier | Based on location e.g. within drainage schemes where culverts are flooded or dry. | Field assessment |
| 1.3 – Bridge – Single span bridges cannot be confirmed until site visit | Not a barrier | Saved for future reference |
| 2 – Fish passage remediation fitted (all species) | Ramp, baffles rope or other | Monitored |
| 3 – Fish passage remediation fitted (climbing/jumping species only) | Ramp, baffles rope or other | Monitored |
| 4 – Perched/overhung | Perched outlet, apron, flume or other | Remediation at outlet |
| 4.1 – Perched but no velocity/bed info | Older apps or data incomplete | Remediation at outlet – be prepared to treat for velocity |
| 5 – Velocity | Usually no bed material | Remediation |
| 5.1 – Velocity but no perch info | Older apps or data incomplete | Remediation – be prepared to treat outlet |
| 6 – Perched & Velocity | Both perched and velocity barrier | Remediation |
| 7 – Physical | Blocked. Only allowing water to seep. Also tide-gates & pumps | Remediation and/or maintenance |
| 8 – Requires further investigation | Limited data. Difficult access or permission required | Requires further investigation to obtain more information |
| 9 – Natural Feature | Waterfalls, cascades etc “Usually picked up during stream walk” | None |
| 10 – Dry and/or no upstream aquatic habitat | Dry gullies etc Low priority fix if fixed at all | None |
| 10.1 – Road runoff | E.g., Cross drains | None |
| 11 – Structure requires maintenance | Dysfunctional/damaged structures Scores 4 or 5 in Status Condition. | Needs maintenance before remediation |
| 11.1 – Fish Passage requires maintenance/upgrade | From monitoring survey | Maintain or upgrade |
