Spring Breakup, Summer Monitoring, Hydrological Assessment and Culvert Monitoring Report Greater Moose's Tooth (2018-2021)

Spring breakup is generally considered the largest annual flooding event in this region of the North Slope of Alaska. Preliminary hydrologic and hydraulic assessments of the Tinmiaqsiugvik (formerly Ublutuoch) River were conducted by URS in 2001-2002. Michael Baker has conducted breakup monitoring and hydrologic assessments throughout the GMT1 area annually from 2003-2006 and 2009-2014.

The objective of the GMT2/MT7 culvert monitoring program is to monitor and document culvert performance and to evaluate areas where additional culverts or modifications to existing culverts are necessary to maintain natural drainage. Culvert flow is typically limited to the spring breakup season when meltwater is conveyed across the road, generally equalizing ponded water on either side of the road.

Greater Moose’s Tooth 2 (GMT2/MT7) Spring Breakup Culvert Monitoring supports the ConocoPhillips Alaska in meeting State of Alaska, federal, and local permit stipulations. GMT2/MT7 facilities include the GMT2 access road and pad. The GMT2 access pad, road, and 80 culverts were installed during the winter of 2018-2019.
