Sponsored Student Cancellation Policy

If you are selected for a student sponsorship and later determine you are unable to attend the conference after you register, cancellation requests must be received by the Hydrology Days Planning Committee no later than April 15, 2022 so we can offer another student the opportunity to attend in your place.  Students who do not contact the committee may be required to cover the regular student registration fee of $50.

This event is organized by the One Water Solutions Institute at Colorado State University.  For questions or comments regarding Hydrology Days please contact:
