Check that the location of the crosshairs matches your location. If not, drag the crosshairs to the correct location.

Select STREAM TYPE.

Take a photo of the stream or select one of your photos from the album. The picture should show where you made the observation. Thus it is useful if it includes a prominent feature, such as a tree, big rock, wall or bridge.

Indicate the size of the watercourse. The classes are only approximate, so there is no wrong answer.

First, indicate how you would rate the quality of the water in this waterbody. Then, answer some questions about the water and its quality: Is the water clean enough that you would swim in it if it was safe to do so? Only consider the water quality for this question, that is ignore other safety aspects such as animals, rapid flow or the presence of big boats in this question. Is the water clean enough that you would drink it? Also indicate whether the watercourse looks more natural or more human controlled. Furthermore, indicate how clear the water is and what type of river bed material you can see. You can also indicate the colour of the water. Can you see the river bed? Can you see growing plants in the water? Can you see fish or other living beings in the water? Do you observe foam or algae? Does the water smell like something? Is there litter in the water? Do you know if there is an artificial inflow to or outflow from this water body? Is the water polluted? By answering these questions, an overall estimate of the quality of the water gets possible.

If you know that the water body does not carry water all year round, you can indicate this here.

If the water body has a name and you know it, you can write it down here.

Enter a description of the exact location of the spot, so that other participants can find it more easily. Check that the time and date match the time of the observation.
