The blood particles will get diluted and absorbed into the riverbed or consumed by aquatic organisms
The river wont be red like it's hell BUT it will have an impact on the ecosystem.
Orange-ish rocks by the riversides, high iron particulates from the blood.
Aquatic animals get a lot of nutrients. Blood has glucose, sodium, proteins, and iron after all. Expect huge fishes and lots of animals getting fatter. This actually happened irl. The holy river in the Himalayas have huge fishes from eating cremation ashes.
Plants would get fertile soooo the riverside farmlands of /meat/ naturally have huge produce. Blood is organic fertilizer.
Ironically /meat/'s natural ecosystem would benefit from dumping blood into the river
