About
Wild & Scenic designation protects 38 miles of the Delta River through Bureau of Land Management corridor in Alaska's interior. Spring snowmelt and glacial sources push flows from 1,450 CFS at low water to over 4,400 CFS during peak runoff, with 2,922 CFS average recorded at USGS gauge 15348000. The BLM manages this as undeveloped wilderness water, requiring coordination for access and egress in roadless country. Remote and demanding, the Delta runs through country where self-sufficiency isn't optional.
