Reid, S. B. 2017. The lampreys of the Grass Valley drainage: distribution and passage barriers, 2016; including an assessment of Buckhorn Dam as a barrier to pacific lamprey. Report for the Trinity River Restoration Program (TRRP). Stewart B. Reid, Ph.D., Ashland, Oregon. Available: www.trrp.net/library/document?id=2355.
The goals of this project are to:
1) Distribution: determine the distribution of lampreys in the Grass Valley drainage,
2) Passage Barriers: assess potential passage barriers on Grass Valley and Little Grass Valley,
3) Buckhorn Dam: assess passage issues at Buckhorn Dam, and
4) Hamilton Ponds: evaluate habitat use by larval lampreys (ammocoetes) in the Hamilton
Ponds, in order to minimize impacts during management operations (sediment removal). This report addresses distribution and passage assessments, including Buckhorn Dam. A separate report focuses on distribution and habitat use by ammocoetes in the Hamilton Ponds (Reid and Goodman 2017).
Performed under contract to the Trinity County Resource Conservation District with funding from TRRP.
