Reports from a public information officer from the city of Houston claim around 1,000 hurricane evacuees remain at the George R. Brown Convention Center.
There were about 10,000 evacuees in the mega-shelter last week.
Evangelina Vigil, a spokeswoman for the department of neighbourhoods, gave The Associated Press the updated number Saturday afternoon.
The Red Cross said Saturday that 37,000 people stayed in shelters on Friday night due to Harvey.
On Saturday, people still housed at the convention centre lined up to file FEMA claims and took photos with Shasta, the University of Houston mascot, while others prayed with a Catholic priest.
