Hydrologic Survey Regional Offices

Northern Region

The Northern Regional Office, located in Fairbanks, provides services and data collection throughout the state. Analytical services are provided through the Water Quality Laboratory, located on the University of Alaska Fairbanks campus. Integrating with several University research labs, the laboratory can provide inorganic analysis and wet chemistry covering a wide variety of parameters.

Primary work involves stream sediment analysis, including turbidity, total suspended solids, and bedload analysis including particle sizing and distribution. Other facets include automated major anion chemistry and metals analysis on groundwater and surface water.

Field activities in the Northern Regional Office include groundwater and surface water sampling and monitoring, site surveys, and hydrologic monitoring.

Current and past projects include: mine site reclamation activities consisting of planning, construction and monitoring; operation of several stream gaging stations throughout Interior Alaska; sampling and analysis of contaminated sites for site-specific delineation; basin wide geochemical sampling; groundwater investigation for fish habitat viability; among others.

Southcentral Region

The southcentral field office, headquartered in Anchorage, generally encompasses an area stretching from Prince William Sound, north to the Alaska range, and west to the lower Kuskokwim River, and includes the Alaska Peninsula, Aleutian Islands, and Kodiak Island.

The climate in this area ranges from the mild and wet maritime zone along the Gulf of Alaska and Bering Sea, to transitional in the Anchorage vicinity and Alaska Peninsula, and to the dry and cold continental zone in western Alaska and the south side of the Alaska range.

Rivers in the area include the Copper, Susitna, and Kuskokwim Rivers, and the popular Kenai River.

Notable lakes are, Iliamna Lake (the state's largest), Becharof Lake, and Naknek Lake.

Annual stream runoff in the area ranges from 1 cubic feet per second per square mile (cfsm) in western Alaska to 12 cfsm in Prince William Sound.
