Attendance took a big dip in fiscal year 2019-20 at the Riverside Discovery Center, but officials said that was to be expected with the impact of the coronavirus pandemic. RDC director Anthony Mason told the Scottsbluff City Council Monday night that attendance at the zoo was 34,614 over the last year, down from about 45,000 the previous year. With the big drop in attendance, admission income was down more than $13,000 (about 8%). Traditional visits from school groups and home school groups were canceled in most cases, adding to the decrease in attendance and contributing to a drop of more than $10,000 in group admissions. Admissions for seniors, among the highest at-risk population, was down by one-third, dropping by $2,600.
