Inland Wetlands and Watercourses
{Photographs of inland wetlands}
Connecticut has a long history of protecting its water and land resources. In 1972, the state legislature enacted the Inland Wetlands and Watercourses Act (IWWA, sections 22a-36 through 22a-45 of the General Statutes of Connecticut), which requires the regulation of activities affecting the wetlands and watercourses of our state.  In 1987, the IWWA was amended to declare it is the "public policy of the state" to require municipal regulation of such activities.  The DEEP Inland Wetlands Management Section provides training, regulatory, and technical assistance to Connecticut’s municipal inland wetlands agencies.  For information regarding inland wetland and watercourse management and protection please view the links provided on the left side of this web page. Connecticut's citizens will find the General Information link helpful. 
The Statewide Inland Wetlands & Watercourses Activity Reporting Form has been updated to reflect year 2019 and to provide an additional resource (link) for subregional drainage basin maps.  Please view the Status and Trends page to obtain a fillable Word or PDF version of the reporting form, and for municipal Inland Wetlands Agency reporting requirements.
