How Does the Poudre Compare to Golden/Lyons?

Fort Collins generally has higher flows than Lyons!

– And the flows last longer too – Caveat – Lyons data is for Black Bear/Arn’s Hole, not October Hole

Above 100cfs, FC flows are similar to Golden
Note:

– FC & Golden data are USGS 38 year averages – Lyons data are CO Div of Water 12 year (‘00-’12) averages

How Does the Poudre Compare to Golden/Lyons? 2008-2012 Data

Looking at only the last 5 years (2008-12) Fort Collins is

similar to Lyons, but with more high flow days.

– Caveat – Lyons data is for Black Bear/Arn’s Hole, not October Hole

Note:

– FC & Golden data are 5 year averages based off of USGS data – Lyons data are 5 year averages based off of CO Division of Water data
