And here's the Minnows with the @GoPro 12 (I need to sort the macro settings). The Minnows, Brown Trout & Stone Loaches were all at highest density around a deposit of flinty gravel (perhaps part of a river restoration project?). #chalkstreams #RiverGranta #babraham #minnows 5/12

The water visibility was so poor, & in many places the River Granta so shaded, that didn't have much luck with filming the minnows. Here's from my @OlympusUK TG7 (probably on the wrong setting!), but gives an idea of the frenzy. #chalkstreams #RiverGranta #babraham #minnows 4/12
