3rd Annual Uncompahgre River Classic

Thank you for all who predicted when the Uncompahgre River will reach its peak flow. No more predictions are being taken as the deadline was May 1. We’ll inform you on June 24 of who won great prizes!

The Uncompahgre Watershed Partnership (UWP) is raising awareness about the importance of understanding streamflows and peak flows through an annual contest – the Uncompahgre River Classic. Keep up with the Classic updates to learn about how important river flows are to our watershed. Plus, you can enter the contest with your prediction of the date and time that the Uncompahgre River above the Ridgway Reservoir will hit its peak flow this May and June to win great prizes!

  • One FREE entry per person!
  • Entry Period: March 1 to May 1, 2023.
  • The winner of the Uncompahgre River Classic will be announced at Ridgway RiverFest on June 24.
  • Only people who are 13 years old and up may enter, but we encourage families to make predictions together with their children.

What do you know about streamflows and the peak flow of the Uncompahgre River?

The staff and board of UWP hope you will take this opportunity learn more about the Upper Uncompahgre River Watershed by checking out our streamflow blog posts. Please go to these webpages to read about how and why monitoring streamflows and annual peak flows are important, and while you are on each page, test your knowledge with our mini quizzes. It’s fun plus you can win a RiverFest shirt!

Price: One entry per person. Each entry is free but UWP would really appreciate a donation if possible to help us fund watershed awareness campaigns and water quantity monitoring and analysis.

Guess/Entry Purchase Period: March 1 through May 1, 2023

Peak Flow Predictions: Entrants must predict the date and the time of the Uncompahgre River’s peak flow from spring runoff between May 1 (12:00 a.m.) through June 23 (11:45 p.m.), 2023. Predictions will be in increments of 15 minutes i.e. 12:00, 12:15, 12:30, and 12:45.

Winner Announcement: June 24, 2022 (at Ridgway RiverFest). You do not have to be present to win. Winners will also be notified by email and phone.

Peak Flow Determination: The correct prediction will be based on the peak flow of the Uncompahgre River, above the Ridgway Reservoir, that results from snowmelt between May 2 and June 23. UWP will use measurements from the U.S. Geological Survey gage at County Road 24 to determine the top three predictions.

Winner Determination: The winner of the Uncompahgre River Classic will be the entrant who predicted the closest date and time to the actual date and time of the peak flow. If more than one entrant is equally close to predicting the correct date and time, the entrant who paid for their entry first will be the winner. If more than one entrant is equally close or correct in their prediction and paid for their entries at the same time, the entrant who also predicts the flow rate (cubic feet per second) closest to the actual peak flow will be the winner. The second through fifth place winners will be determined similarly. Each entrant may only win one prize. If entrants have more than one of closest prediction among the top five, they may not win a second prize. The entrant with the next closest prediction will be selected to win the next prize.

Disclaimers: Flows outside the designated peak flow period outlined in the contest rules, and in locations other than the designated U.S.G.S. gage will not be considered in this contest.

Eligibility: Only people who are 13 years old and up may enter the contest (families with children under 13 are encouraged to make their predictions together and enter under the parent/guardian name). Board members and contracted staff of the Uncompahgre Watershed Partnership as well as immediate family members living in their household are not eligible to win prizes in the Uncompahgre River Classic.

Prize Pickup: Winners must pick up their prizes in Ridgway, Colo. UWP will not ship prizes, unless winners pay shipping costs.

Entrant Agreement: By entering a prediction in the Uncompahgre River Classic, the entrant agrees to receive emails from UWP through the period of the contest: March 1 to June 26. Emails will primarily give updates on the contest, educational information about peak flows/streamflows and related UWP activities. Afterwards, entrants will only continue to receive emails from UWP if they subscribe to updates on the form in the top right margin of UWP’s website or at the link in the thank you confirmation for each purchase. UWP may also send one mailing to entrants’ mailing addresses annually related to our nonprofit’s membership drive. Please email info@uncompahgrewatershed.org if you wish to be taken off the membership drive list. UWP will only give entrant contact information to the contest sponsors, who may contact you but must request your permission to be added to any regular mailing lists.
