The State of Alaska Department of Natural Resources (ADNR) Office of Habitat Management and
Permitting (OHMP) oversees fish habitat permitting in the Colville River Delta. The purpose of the 2007
Colville River Delta Lakes Lake Recharge Monitoring and Analysis project was to document the
mechanisms and extent of recharge for 30 lakes identified by CPAI (CPAI 2006), to support removal of
six inches of grounded ice in addition to permitted water withdrawal volumes If lakes are shown to have
adequate recharge, ice chips can be removed from grounded ice without impacting fish habitat. The
OHMP approved removal of additional ice chips for the 30 lakes for the 2006/2007 winter season only.
The location of each lake within the CRD is presented in Figure 1-1.
