I took a look at the CFs on the major Croton streams to see how they were flowing after Tropical Storm Irene. Since the DEP controls water levels, I was thinking they were releasing a lot of water from the reservoirs into the outlets. That combined with the runoff, I expected it to be high...but not this high. Pretty dramatic differences.
- East Branch (Croton River just below dam): median CF = 63, right now, CF =2460 , gauge height, 7' 3" and falling
- Croton Falls Outlet (Croton River West Branch): median CF = 70, right now, CF = 430, gauge height, 6' 6" and falling
- Amawalk Outlet (Muscoot River): median CF = 19, right now, CF = 241, gauge height, 10' 6" and rising
- Titicus Outlet: median CF = 12, right now, CF = 2,180, gauge height, 8' 7" and peaking
- West Branch Outlet: median CF = 32, right now, 846, gauge height, 4'1" and rising
- Cross River (in Ward Pound Ridge): median CF = 4, right now, 825, gauge height, 6' 2" and falling
The EB is 39X normal flow. TO is 181x normal flow, but Cross River takes the prize at 206X normal flow!!
Seeing how Cross River has the only native brook trout population in the area, that's quite worrying. On the other hand, the buildup of silt on all the rivers should be lower after the flooding, right?
For the heck of it--looked at the Esopus Creek up in the Catskills: median CF = 261, right now, CF =59,900, gauge height, 16' 9" but earlier was 21'. The Esopus is 229X its normal flow...I'd say that's got to be a flood.
...I can't begin to imagine the damage. Hope everyone is staying safe.
