Weekly Monitoring
Import dated workbook observations, review changes, and explore each weir’s annual water-level history.
Workbook Intake & Annual Monitoring
Drop → review → apply. Accepted observations feed the charts and map previews.
Your supplied history is included below. New imports save in this browser only. Cross-device storage and live telemetry are not connected. Reported riser / bladder Y/N fields never become confirmed operating status.

Understand inches, gallons and rainy-season headroom
Weekly “Total Inches Available”: each listed weir contributes (gauge elevation − workbook shutoff) × 12. Adding those values makes an unweighted depth index. It does not measure rainfall, gallons, or empty storm capacity. W16 and W17 both contribute even though they serve Basin 4.
| Reading date | Year | Summed depth index · inches |
|---|---|---|
| Sep 15, 2026 | 2026 | 496.68 |
| Sep 15, 2025 | 2025 | 438.60 |
| Sep 16, 2024 | 2024 | 455.40 |

Volume workbook: uses basin canal surface area × depth above its reference × 7.48 gallons per cubic foot, then sums basin estimates. Its arithmetic is not capped at the green line, so higher gauge stages can produce estimates above it.
Source limitations: Basin Data 26 contains broken references in other calculation blocks. The plotted volume total instead uses rows 98–115; basins 17 and 18 are hardcoded to zero there, and some basin areas are blank. Confirm area, gauge mapping, elevation references and current geometry before using it as an operating model.
Seasonal operating target: stored water supports supply; empty space above the current water surface provides storm headroom. Neither historical line establishes how much should be retained before rainy season. That target needs basin-specific operating elevations and storage relationships.
Sources: Canal Volume Trends Current.xlsx · active Canal Vol (2026) chart; Basin Data 26, BV119; Basin Data 16, row 122; Basin Data 11, row 123. Depth-index comparison: 9-September.xlsx, Reading 3, row 22. Updated volume workbooks refresh this comparison after review; depth-only imports do not recalculate gallons.
Annual Water Levels · By Weir
One chart per structure, in numeric order. Hover a reading point for its date, elevation and source.
Levels use the workbook’s NGVD label; gauge location and datum details need confirmation. Chart scales adapt to each weir, so compare the labeled elevations rather than line height across cards. Storage volume and confirmed gate positions remain separate.
Basin volume & live telemetry · next connections
These workbooks provide depth above a shutoff reference. Their summed inches are not gallons. Basin storage requires a validated stage–volume relationship and must not be counted once for each outlet. A future telemetry connection will provide timestamped upstream/downstream observations and confirmed control positions without replacing newer data with older weekly readings.
How to read this page · box-by-box guide
| Box | What it shows | Limits / still needed |
|---|---|---|
| Weekly Field Reading Entry | Records a dated field round: stage, reported state, workbook shutoff and notes. Δ Prior compares with an earlier reading; inches = (stage − shutoff) × 12. | Confirm datum and the workbook’s Y/N state definitions. Workbook shutoff is not a gate setting. Save local draft stores only in this browser. |
| Workspace Data | Shows where drafts are saved. This version uses copied reference readings and local browser drafts. | No automatic sync with Brad’s workbook or cross-device database is connected. |
| Basin 4 Focus | Latest loaded readings for W16, W17, W58 and W21. | These are dated observations, not live gauges. Gate positions, rainfall and upstream/downstream readings would complete the picture. |
| Annual graph and controls | Each color is one year; dots are recorded levels aligned by month/day. Loaded data window avoids empty months. Hover or click a dot for its date and source. | Supplied workbook history spans multiple years; date conflicts are withheld. Lines link readings up to 21 days apart; they do not measure what happened between rounds. |
| Latest 2026 / 2025 near same date | Shows the latest loaded 2026 reading and one 2025 reading within 14 calendar days of the same seasonal date. | The dates can differ. A year with no reading in that window has no comparison. |
| 2022–2025 same-period average | Averages one nearest reading from each available prior year within 14 calendar days, not all readings in that month. | This is a small historical reference, not a seasonal operating target. Configuration and rainfall may differ between years. |
| Change since prior 2026 reading / comparison signals | Differences in feet or inches: latest versus previous 2026, versus 2025, and versus the historical reference. | Higher or lower is a direction, not a good/bad rating. The previous reading may be more than a week earlier. |
| Year comparison chart / Executive interpretation | Displays the same near-date observations by year and summarizes the differences in plain language. | It cannot attribute a change to a gate action or rainfall, or tell you which gate setting to use. |
| Chronological readings / System snapshot | Lists source dates and values for the selected weir, then compares all listed weirs with their own latest dated readings. | Different weirs may have different latest dates. Source rows are reference copies, not a direct workbook connection. |
| Operations Intelligence | Lists documented control changes. Optional dashed markers show actions only within that year’s loaded level coverage. | Dates alone do not prove cause and effect. Need action time, gate/riser settings, rainfall and upstream/downstream stages. |
| Hydraulic context | Legacy model comparison of existing versus proposed flow at a fixed 7.3-foot upstream stage and varying downstream stage. | Not measured discharge and not a validated rating curve for the as-built gates. Need model/source review and current calibration. |
| Estimated basin storage | Reserves a place to translate water level into basin storage. | Not calibrated: need a validated stage–volume relationship for the relevant basin and current canal geometry. |
| Rainfall & Telemetry Sources / Rainfall Observation | Lists candidate/reference services and provides a rainfall entry form. | Ready means a potential source, not an active feed. Rainfall saving is disabled without an independent backend; SCADA access remains needed. |
| Trend Analysis / Reading History | Shows loaded weekly/local observations on a real date axis and groups those observations into dated rounds. | This is a separate, smaller current-round dataset from the multi-year workbook comparison above. Missing weeks stay missing. |
Weekly Field Reading Entry
The analysis is date-based. Workbook labels such as “Reading 1” or “Reading 2” are treated only as source references, not as analytical cycles.

This focus panel is intended to evolve into an operational Basin 4 summary combining weekly levels, gate settings, rainfall, and eventual SCADA history.
Annual Water-Level Trend
All dated weekly readings are combined into one calendar timeline and overlaid against prior years.
What the chart means
Each dot is one actual dated field reading. The Hub no longer compares “Reading 1 vs Reading 1.” Instead, it combines every reading chronologically so you can see how each weir behaves through the year and compare the shape of 2026 with 2025, 2024, 2023, and 2022.
Going forward: every weekly round saved in WB Hub automatically extends the 2026 line. Additional historical monthly workbooks can be added to fill Jan–Aug and Nov–Dec.

“Inches above shutoff” remains the workbook-derived measure (NGVD stage − shutoff elevation) × 12. It is not volumetric storage or gate opening/headroom. W16/W17 workbook shutoff values have not been replaced with gate operating limits. Higher/lower colors indicate direction only; they do not automatically mean good/bad operational conditions.
Operations Intelligence
Levels + documented control changes + hydraulic context for the selected structure.
Operational action markers
Optional dashed chart markers = documented actions, not water-level readings. Use “Show documented actions” above; the timeline retains all loaded actions.
Hydraulic context
Estimated basin storage
Not calibrated yet.The legacy Canal Volume Trends workbook contains useful stage/storage concepts, but WB Hub will not convert stage to gallons until the applicable basin stage-volume relationship is validated for current conditions.
Rainfall & Telemetry Sources
What is connected now, what is ready, and what still needs City/provider access.
Rainfall Observation
MANUAL READYRainfall saving requires an independent backend, which is not connected yet. The listed telemetry sources are references; automatic ingestion is not enabled.
Trend Analysis
Dated readings and local drafts, with real spacing between dates.
Reading History
The original workbook remains a source record. WB Hub stores each reading as a time-stamped operational observation so it can be compared with structure actions and events later.
Weir Register
Master City weir list + live GIS attributes. The register remains usable even if the GIS service is temporarily unavailable.
| Weir | Canal | Location | Carp grate | Riser/control | Up basin | Down basin | Sill NGVD | Min crest | Max crest | Crest length |
|---|
Basins
The basin module is ready; authoritative polygons will be added when the internal layer is available. Upstream/downstream basin attributes from City GIS are already used at the structure level.
Events
Event reconstruction is a separate layer beneath daily operations.
