The Mackenzie Valley Resource Management Act (MVRMA) which was proclaimed December 22, 1998, empowers the Sahtu Land & Water Board to regulate the use of land and water by issuing, amending, renewing and suspending land use permits and water licences throughout the Sahtu region. This authority extends to all crown, Sahtu lands and private lands. The MVRMA prescribes the Mackenzie Valley Land Use Regulations, the Northwest Territories Water Act/Regulations as the principal regulatory instruments for the Board to use.
