Think about the story you want to tell. Is it a continuation of the existing plot? Or something completely new? Decide on the main plot points, like the mystery or conflict your characters will face.
You can try looking on popular fanfic websites like Fanfiction.net or Archive of Our Own (AO3). They have a vast collection of Harry Potter fanfics, and you might be able to find the 'Crimson Rivers' one by using the search function on those sites.
