River, streams and wetlands in Medellín
Explore 817 municipal drainage-network records, the published Medellín River polygon and 113 wetland and lagoon polygons from the 2014 land-use plan. Five wetland records have published names; the other 108 retain their identifiers without invented names. Also explore 27 water-supply catchments with published aqueducts and rural districts. Find a stream, compare main and secondary drainage and analyze mapped lengths or areas.
Explore these layers ↗Reference mapping: every record reports an update of December 17, 2014. The five named water bodies are already included in the 113 wetland polygons; do not add both layers as distinct sites. The 817 records are not unique streams, and the 113 polygons do not establish current field-verified wetlands. Length and area describe complete geometries, without clipping to the analysis area or dissolving overlaps. The drainage network retains simplification of up to one meter; wetlands and water-supply catchments retain the full server coordinates. This is not the municipality’s 2025 satellite model and does not establish current channels, setbacks, flow, water quality or flooding. SIATA readings are available separately under River and stream levels.

How to use itHow to use the map
- Open the prepared query for this theme in the viewer. Search a neighborhood or enter coordinates as latitude, longitude.
- Review enabled layers in the theme and zoom in. Detailed layers require a close scale to keep queries bounded.
- Select a feature on the map or in the Results list. Check its attributes, retrieval time and any partial-result notice.
- Choose a field and exact value to filter the layer. Export includes received results, with attribution and dates. Its coverage depends on the query scope and filters.
Frequently asked questions
What does River, streams and wetlands include in the Medellín geovisor?
In Medellín’s River, streams and wetlands you can explore 5 layers: Wetlands and lagoons · 2014 planning reference, Water-supply catchments · 2014 land-use plan, Drainage network · 2014 reference and 2 more. Each layer states its source, date and use limits.
Can I reuse the River, streams and wetlands data?
According to each layer’s published license: CC BY-SA 4.0 and Cartografía pública municipal · licencia específica no indicada. Check the exact license on the layer record before reuse.
How current are the River, streams and wetlands data?
Layers declare data dates from 2014-12-17 to 2014-12-17. Last GeoSAT verification: 2026-09-29.
How do I explore River, streams and wetlands in the viewer?

Sources, dates and limits
Each source’s verification date appears in the table. Retrieval time is not the data update date. Small city-wide layers use the full extent; larger layers depend on the visible area. Reference publications retain their original retrieval date. Each page contains up to 500 features: up to 2 MiB for external services and 4 MiB for local publications. Reference publications load matching pages, up to 5,000 features and 8 MiB per query. External services may return partial samples, identified in the viewer.

Metadata lists the five known water bodies, but its geometric count also states 113. These are not 113 distinct wetlands verified in the field. The five named records already appear in Reference water bodies: do not add the two layers as separate sites. All records state adoption and update on December 17, 2014; metadata declares a March 19, 2015 revision. Complete original geometry is retained. Calculated area describes the mapped footprint, not available water, ecological condition or current boundaries. Wetland setbacks are not included, and public access is not established; consult the adopted map and competent authority.

Every record has adoption and update dates of December 17, 2014; the metadata was published and revised on March 19, 2015. Every component, hole and WGS84 coordinate returned by the server is preserved. Five records do not name an aqueduct and two do not name a rural district. These areas relate to reserves and aqueducts in other layers: their areas should not be added as independent coverage. They do not describe flow, water quality or current water-supply operation.
