The Alaska Hydrologic Survey performs meteorological studies, often as components of larger hydrologic investigations or projects. The Alaska Hydrologic Survey maintains several public information databases, in various formats. This is a statewide well log tracking system database. It is an index to the files of over 25,000 well logs that have been submitted to the Hydrologic Survey, as required by state statute. Other well logs are obtained from various sources, including water rights applications.
Public access is supported and encouraged.
The online version of the Welts database requires Adobe Acrobat Reader to view the well logs. Click here to download a free version of Acrobat Reader. This database is a summary of stream characteristics resulting from an initial investigation into navigable streams within the state. The database has continued to grow as new data becomes available. This is an electronic record of all discharge measurements made by the Hydrologic Survey staff over the years.
