How Does the Poudre Compare to Golden/Lyons? Days at or above Flow rate Flow Rate Fort Collins Lyons Golden 50 cfs 153 150 258 100 cfs 101 111 154 200 cfs 77 66 95 300 cfs 58 42 69 400 cfs 49 9 56 500 cfs 39 0 44 1000 cfs 6 0 0 2000 cfs 0 0 0 • 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 Days at or above Flow rate Flow Rate Fort Collins Lyons Golden 50 cfs 164 145 244 100 cfs 91 104 147 200 cfs 59 58.4 83 300 cfs 45 42.2 59 400 cfs 39 29.6 48 500 cfs 31 17.2 41 1000 cfs 18 1.4 11 2000 cfs 8 0 0 • 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
