5.2 Interactive Map of the 2027 RMS Network

26 polygons anchored by 29 RMS wells (13 North, 4 Chico — plus 5 supplemental nested completions in Chico shown for hydrograph context, 12 South) — three-zone method shown by default. The Chico polygon is the dissolved Chico management area. Three of the 13 North RMS wells physically sit inside the Chico mgmt area but their Thiessen cells are clipped to N proper (no overlap). Click a polygon to drive the hydrograph in §5.3 and the representativeness comparison in §5.4. Click a well marker for a metadata popup.

5.3 Polygon Hydrograph & Well Detail

For the selected polygon, this view plots groundwater elevation traces for every well (RMS or supplemental) that falls inside the polygon footprint. MT / MO / IM-2027 threshold lines are shown where 2022 GSP values carried forward.

MT raise: +0 ft Adjust threshold for each well's elevation (one-sided: only when domestic well GSE > RMS GSE)

Drought period (1991-93, 2012-15, 2020-22) MT (Minimum Threshold) MO (Measurable Objective) IM-2027 (Interim Milestone) MT raised (slider)

Domestic-well sensitivity to MT

Of the 1,253 domestic wells in the LWA inventory, how many sit at an elevation that would make them "dry" if water levels fell to MT — and how that count changes if MT were raised. Toggle elevation correction (above) for the one-sided foothill adjustment. Dry = the well's bottom elevation (AMSL) sits above the threshold; if the basin's water level fell to the threshold, the well would have no water to pump.

5.4 Representativeness Comparison

Same-month paired groundwater elevations (RMS well on x, comparison well on y) with a 1:1 reference line. Pearson R² and n are shown in the legend when at least 5 paired readings are available.
