Public water reading
Medina, Cundinamarca, RAP (Especial) Central
Medina, Cundinamarca, Colombia · 4.4379, -73.2494 · one hundred thirty-seven hectares of water
The signs are mixed. The plan comes first.
This body of water is workable water that is turning — the plan must come before the capital, scoring 42 out of 100. Something discharges to, or works beside, this water. The division screens high for river flood, urban flood. 11 of 12 sources answered; the silent ones lowered confidence, not the score.

The water
What this body is, how it reads from orbit, whether it stays, and the basin it sits in.

What the shore is made of, what lives here, what presses on the water, and what the climate does to it.

Expect is the honest verb: the middle of a range of futures, one scenario, not a certainty. Warmer air means warmer, more stratified water and more evaporation.

The reading
What the figures mean together, what to do first, how to check it, and what only the water itself can answer.
Findings
- Risk
Something discharges to, or works beside, this water.
A mapped outfall or industrial edge is a point source to ask about before any other question; the map shows presence, never what leaves the pipe.
Industrial land use on the shore within about 3 km, from the public map. · medium confidence
- Risk
The division screens high for river flood, urban flood.
A screening class at administrative scale — a prompt to read the shoreline and the record, not a site assessment.
ThinkHazard (GFDRR) for Cundinamarca, Colombia. · low confidence
- Permanence
The archive shows how much of this boundary holds water, and how often.
Permanence is the first property of a water asset: what stays can be planned around; what comes and goes must be designed for.
0% permanent, 0% seasonal; where water was seen it was present 0% of the time (JRC Global Surface Water, Landsat 1984–2021). · high confidence
- Climate
The surface of the water read 23.2 °C on the latest clear thermal pass.
Surface temperature governs how much oxygen the water can hold and how fast it stratifies.
Landsat Collection 2 surface temperature, 2026-02-28; a skin reading from orbit, warmer than the water a metre down. · medium confidence
- The shore
The shore is mostly natural cover.
The edge decides what reaches the water: a wooded or wetland shore filters runoff; a built or cropped shore delivers it.
300 m ring: Grassland 60% · Tree cover 40% (ESA WorldCover 2021, land pixels only). · high confidence
- Life
The species record here is thin.
Occurrence counts measure where people have looked as much as what lives here; a thin record is an unknown, not an absence.
9 GBIF occurrence records inside the boundary; most recorded: Scaura latitarsis, Partamona peckolti. · low confidence
- Climate
Expect the seasons here about 1.4 °C warmer by 2050, with 31% less rain.
Warmer air means warmer, more stratified water and more evaporation; less rain means less inflow. Expect is the honest verb: this is the middle of a range.
CMIP6 (MPI-ESM1-2-XR, SSP5-8.5) 2045–2049 against the 2004–2024 record; longest dry spell expected 21 days. · medium confidence
- The body
0% of the boundary is open water in the land-cover record; the public map does not name it.
An unnamed water is not an unknown one — the archive still says how much of the boundary is water and whether it stays — but its kind, its operator and its rights are yours to establish.
0% open water (ESA WorldCover 2021). · low confidence
- The basin
The water surface sits at about 922 m above sea level.
A lake's altitude sets its temperature regime and tells you how far its water has to fall to the next basin.
AWS Terrarium z12 (ETOPO1 below sea level), 33 samples, 276 m of relief across them. Bathymetry is ETOPO1-grade (~1.8 km): a screen, never a chart. · medium confidence
What it means together
About 1,407 mm of rain falls on this water in a year, and the water stays: most of the boundary has held water through four decades of passes.
The shore is 100% natural cover, so what reaches the water is filtered first.
This body of water is workable water that is turning — the plan must come before the capital; the weakest reading is climate resilience, and that is where the leverage is.
What to do first
- 1
Take a baseline in four bottles before anything changes.
Every figure here is read from orbit or the public record; a baseline on the water is what makes the next reading a trend.

Open questions
- —Who holds rights to this water — to take from it, to discharge to it, to fish it — and who enforces them?
- —What is in the sediment on the bottom — the memory of everything the catchment has sent down?
- —What is the land above doing this year that the satellite has not caught up with yet?
