Free reservoir widgets for your website

A widget is a chart of the current fill, the last 12 months, and the same period a year earlier. It is free. The frame has no ads. The line “Data: reservoirs.earth” stays in the frame and links to the page for that figure. That credit is required. CC BY 4.0 covers only reservoirs.earth's derived data. The official source data follows each source's licence.

Use one in three steps

  1. Open a reservoir, a basin, or a country page that publishes a fill chart.
  2. Choose “Embed this chart”, or open the builder and pick the chart there.
  3. Copy the snippet and paste it into your page.

Examples

FAQ

What does it cost?

Nothing. The chart does not ask for an account or a payment. The credit line stays in the frame.

When does the chart update?

The frame shows the figure from the latest data deploy. It changes when that deploy updates the site. The light widget may be cached for up to 3 hours.

What sizes are there?

Compact is 320 pixels wide, Standard is 480, and Wide is 640. Responsive is the full width of the column. The builder sets the height to that chart. A chart it has not measured falls back to 372, 348, 344, and 388 pixels. The chart area is at most 140 pixels tall and lines up with the legend. The fallbacks clear the tallest chart from 200 pixels wide upward, and they keep the axis, the legend, and the credit visible without a script. Compact may clip below 248 pixels, Standard below 280, Wide below 320, and Responsive below 200. Responsive is measured from 200 to 1200 pixels. Include the resize script with it. A chart with no 12-month line is at least 250 pixels tall on every size. Eswatini is 250. Where the card is taller, the snippet uses that height. On a screen narrower than 340 pixels, the percentage sits under the name.

What attribution is required?

The credit is a normal link with rel="noopener". It is not marked nofollow. It opens the page for that figure. CC BY 4.0 covers only reservoirs.earth's derived data. The official source data follows each source's licence. Removing the credit breaks that term.
