Poachers raided Rimoi National Reserve in Elgeyo/Marakwet and killed two elephants.
Kenya Wildlife Service rangers found the carcasses at Chegilet near Kerio River.
Chief Warder Dominic Kilonzo said on Wednesday the elephants killed in Rimoi were aged between 20 and 25.
"They used poisoned spears while the animals were drinking water in the river and took away their tusks," he said.
The warden added that one suspect had been arrested in Baringo North District and rangers recovered ivory worth Sh80,000.
He explained: "The suspect had hidden the tusks in a cave near his house about 15 kilometres from where they killed the elephants."
Kilonzo called for concerted efforts between Keiyo County Council and the public to curb poaching, which has potential to kill tourism.
Last week, suspected poachers killed another elephant in Kiptopich in Baringo North District that had strayed from the reserve.
The reserve spreads along the Kerio Valley and boasts of a population of 400 wild animals, making it an ideal destination for tourists.
