Fish Creek Watershed

Station Name:: Upper Crea Lake (L9820)
Latitude:: N 70.267°
Longitude:: W 151.386°
Elevation:: 7.7 masl
Lake Area:: 129 ha
Mean Depth:: 1.1 m
Record:: 2011-present
Purpose:: This shallower sister lake connected to Crea Lake regularly freezes solid, yet still supports summer fish habitat. It is also used a water supply lake for GMT1. This site was also part of the Circum-Arctic Lake Observation Network (CALON) from 2012-2015. Notable strandlines suggest it was once larger and deeper and may have partly drained.
