Summary
No account is needed to submit waters or corrections. An account credits your work to you. Accounts are required to submit photographs or catch reports.
Two things publish the moment you send them: which species are in a water, and how hard it is to get to.
Everything else is read by a person first — the permission, the price, the ticket link, who controls it, the boundary, and every word of free text.
Adding a water
Draw it on the map, then describe it.
Every submission is manually reviewed.
Correcting something already on the map
- Find the water, from the map or by searching for it.
- On its page, open Help improve this water.
- Choose the section you want to change.
- Input the suggested change.
- Submit the change. You do not need an account.
Use the Report incorrect information button for anything the sections above have no field for, such as the water’s name or its boundary. It goes to the same queue.
Species and access difficulty appear straight away. Everything else is checked by a person first, so a correction can take a few days to appear.
A telephone number has to arrive with evidence — a page on the club’s or fishery’s own site showing the number.
The price and the ticket link are reviewed.
Why all free text is reviewed
Free text is reviewed to prevent spurious submissions or offensive text being displayed on the site. As everything is human-reviewed, submissions may take a few days to appear.
What happens to what you send
Submissions are screened automatically for offensive language, then queued for a person. We store a one-way hash of your IP address — never the address itself — to stop one person flooding the site and to count feedback once per person. See the privacy notice.
Photographs
You can add a photograph to any water. It needs an account.
Location and camera data is stripped from the file before it is stored, so a photograph never records where you were standing. A person looks at every one before it appears, and anybody can ask for one to be taken down.
What happens to a species you add
It appears on the water straight away, as something reported rather than confirmed — “Maybe chub” — and it is left out of the trip planner until it is confirmed. A fish goes on a water's list once two anglers with accounts have reported catching it, once we have looked at a photograph of one, or once we have checked the water against a source that lists it.
