There is still time for students in primary and secondary schools (public and private, K-12) to design a poster for the 24th annual River Sweep 2013.

Fifteen prizes will be awarded. The grand prize is $500, and the school representing the grand prize winner will also receive an award. $500 will be presented to the student with the winning design for the official River Sweep t-shirt. Thirteen $50 prizes will be awarded to one winner at each grade level.
