Gram Panchayat|LGD 228757Directory record
Mariammankoil
Part of Thanjavur block, Thanjavur district, in the Cauvery Delta sub-basin.
No water profile is published for this place
Held back because place-identity-and-composition, population-and-settlements, drinking-water-service are not established for this place.
The Panchayat is listed so it can be found and reviewed. A profile is held back rather than published from evidence that cannot identify the place.
Place and boundary
The mapped extent comes from the TNGIS Panchayat polygon for this LGD code, so the place on the map is the place the records describe.

Groundwater, projected from the taluk
IN-GRES assesses revenue taluks. This Panchayat inherits its containing taluk's category unchanged, as containing-area context rather than a measurement of the place.
Thanjavur taluk, by centroid in taluk.
Groundwater drawn each year as a share of what recharges, for the whole taluk. Above 100 is more drawn than recharges.
Sub-district on the revenue hierarchy, which the Panchayat hierarchy does not nest inside.
The assessment unit is a revenue taluk, not the Gram Panchayat: each Panchayat inherits its containing taluk's category and stage of extraction unchanged, as containing-area context rather than a measurement of the place. Containment is decided by the TNGIS polygon centroid (vertex fallback for concave polygons); a Panchayat that falls in no taluk or in a taluk without an assessment is deferred, never guessed. 8 TNRD blocks span more than one revenue taluk, so a block-to-taluk name match would have been wrong.
Tanks and water bodies
Mapped by TNGIS and assigned to this Panchayat by the register itself, not by a name match.
13 water bodies cover 101.6 ha here, the largest of them 94.3 ha. The register names 7 of them; the names and polygons are withheld pending the TNGIS licence reply.
Waterspread is the mapped extent, not storage. It says nothing about whether these hold water through the year, whether they are encroached, or when any one of them was last surveyed.

Land and irrigation
Census 2011, reference year 2009. A historical baseline, not current cropping.
of 1,044.56 ha total.
canal 395.32 ha, wells 0 ha, tanks 0 ha.
culturable waste; barren 0 ha, forest 0 ha.
Sources through the summer
Census 2011, reference year 2009.
4 source types were recorded for the year and 4 held through the summer months. None failed.
This is the 2009 pattern and says nothing about whether today’s piped supply holds through summer.
