Restoration of a Threatened in a Fluvial Headwater Environment Project Area N

Expansion Area .2008 -2011: beginning of manual removal of in additional 10 miles stream .Future - 2023: continue implementation in streams and begin removal of brook trout in 85 acres of

Meiss Meadows

.1988-1990: rotenone to remove brook trout .early 1990s: LCT re-introduced & brook trout found .mid 1990s: manual removal of brook trout in upper 5 miles stream & 8 acres lake .2007-2009: no brook trout found, resting treatment .one of the only high meadow LCT populations in Sierra

Meiss Meadows Manual Removal Methods

• Late August thru October

• Delineated reaches by natural barriers (low water barriers, falls, and beaver dams)

• 3-pass depletion, on varying reach lenght

• Species identified and measured to size class

• Brook and sacrificed

• Speckled dace returned to upstream reach

• LCT returned upstream of Barrier T1BA4 in RL trib and 36B in UTR; sacrificed below due to hybridization threats 3 Pass Depletion
