Best way to check is to go to Coloradoriver.com, and check out the waterflow reports. It has the most current, and goes back with like a year of reports. It won't tell you what the flow will be in March, but you can look at last year's for March and bet it will be close. Right now the flow at Parker Dam is around 6500; it will be double that come March...so the short answer is the water level will be higher for Spring Break.
