Record Sholinganallur eri (tank) bund condition from the public path (2026-07-18)

Chennai's centuries-old eri (tank) system once cascaded rainwater across hundreds of interlinked water bodies, but many, including Sholinganallur eri, are degraded by encroachment and pollution. A standing photo record from the public bund path tracks condition without any water contact. Standard: Ramsar Convention wetland-of-international-importance monitoring guidance + SDG 15.1. Proof: Photo + GPS + written condition log from the public bund path Method (Ramsar Convention wetland-of-international-importance monitoring guidance + SDG 15.1.): 1. Walk only the public bund path — never step into the eri water or mud. 2. Photograph the eri edge in multiple directions, noting encroachment and water condition. 3. Record GPS coordinates, date, and a written description of what you observed. 4. Note any visible discharge point without approaching it. 5. Submit the photos and notes as your proof — do not touch, enter, or sample the water. Done when: Photo + GPS + written condition log from the public bund path

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

Photo + GPS + written condition log from the public bund path

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA National Wetland Condition Assessment (rapid method)

Bring

• GPS phone
• quadrat frame
• invasive-species ID reference
• boots
• insect protection
• camera

Steps

1. 1. Navigate to the wetland edge; record GPS; stay on stable ground.
2. 2. Photograph 3 quadrat stations.
3. 3. At each station, estimate percent cover native vs invasive; identify the dominant invasive.
4. 4. Note hydrology / water level and any disturbance.
5. 5. Enter cover percentages, invasive ID, hydrology, GPS, photos into the proof record; sign.

If it does not match the plan

• Standing water + wildlife (snakes/alligators) -> maintain distance; never sample alone.
• High invasive cover -> flag for a management/removal plan.

What counts as done

• Percent cover native vs invasive recorded at 3 stations
• Dominant invasive species identified
• Hydrology / water-level note recorded
• GPS waypoints + quadrat photos

Proof is measured against these, not judged by taste.
