Watershed Management is responsible for maintaining the health of stormwater entering the Municipal waterways. Monitoring of discharges and enforcement of clean water regulations are key programs to help protect clean waterways.

An illicit discharge is any discharge to a municipal storm sewer system that is not composed entirely of stormwater. This includes sewage, industrial wash water, machinery repair or cleaning, chemical runoff, pool or fountain water, sediment, clippings, or animal waste. Any of these factors can pollute Anchorage's waterways.The Municipality is creating an inventory and mapping these sites to increase community awareness and facilitate emergency planning in conformance with the Emergency Planning and Community Right-to-Know Act.
We need your help reporting illicit discharge, active water quality, erosion, or stormwater runoff or pollutant problems that do not warrant emergency response but that you think require immediate attention. Our hotline is available 24-hours a day. To report problems, call the Pollution Hotline (907) 343-4141 or report online here.
Watershed Management monitors water quality at stormwater outfalls, through dry weather screening, and by inspecting the effectiveness of structural controls.
