Meeting decisions reflected
Recording 18, Sept 2026 meeting
  • Hierarchy: sectors are the larger unit; 12 reaches nest inside 5 sectors.
  • Numbering: reaches run downstream → upstream and are colored to I-84.
  • Perrine's Bridge: upstream limit is Bontecou Farm, not the Culinary Institute.
  • Springtown: the curvy section (R4) ends at the Springtown bend; bend → rail trail is R5.
  • Hot spot: short R6 runs from the rail-trail bridge to New Paltz Golf Course; Klein Kill and the village sites are in R7.
  • Gardiner: zero DEC rows is an archive gap, not absence of blooms.
  • Upstream: Oil City Rd / State Line Rd are reference points, not part of R12.
