Wet weather has temporarily restricted access to the camp grounds for the Craven Country Music Jamboree, west of Regina.
Organizers said heavy rain from a downpour Wednesday has led to poor conditions for roads on the site.
They said access to the grounds will be restricted until 6 a.m. CST Thursday.
A long line of about 50 cars and recreational vehicles were waiting to get in Wednesday.
Images from the grounds show pools of water and muddy roads.
