History

MSG Project Timeline

1981 – Hatchbox Program: Mill Creek hatchbox established on Rathbun’s property and several thousand donated steelhead eggs hatched, reared, and released. Adult trap and holding box established at A.W. Way Park near Petrolia. Ferro-cement pond and hatchbox facility built near Arcanum Ranch in Mattole headwaters. First native Chinook eggs incubated and reared at Whale Gulch hatchbox.

1981 – Spawner surveys. Comprehensive spawner surveys and carcass counts begun, focusing on assessment of Chinook salmon runs. Thereafter, annual surveys have been maintained at greater or lesser intensity, depending on availability of funds.

1984 – Estuary research project begun on juvenile Chinook and steelhead, in cooperation with HSU graduate students, through 1991.

1985 – Downstream Migrant Trapping via fyke trap near Petrolia begun, continued through 1996 (in cooperation with HSU graduate students, through 1991).

1998 – Road improvements, bank stabilization and instream enhancement at 32 priority sites in upper Thompson Creek (RM 58.4), continued through 1999. This was Phase 1 of the Upper Thompson Creek road rehabilitation project. Phase 2 was completed in summer of 2002.

1998 – Installed 17 instream log cover structures in the upper mainstem Mattole and lower Thompson Creek (RM 58.4).

1999 – Installed 11 instream log cover structures and augmented 2 existing complex structures, in the upper mainstem Mattole and Thompson Creek, completed in the summer of 2001.
