Clear creek drainage
Clear Creek Drainage DRAINAGE

  • Tributary of Sevier River

  • >60 miles of trout habitat

  • 1978: BCT restored in Sam Stowe Creek

  • 2007: BCT restoration plans for three tribs (EA)

  • 2008: BCT remnant confirmed in Pole Creek


Bct restoration
BCT Restoration DRAINAGE

  • 2009: Fish barriers installed at Shingle-Clear confluence

  • 2010: Pre-treatment recon surveys in Shingle Creek (treatment planned for September)


Twitchell canyon fire
Twitchell DRAINAGE Canyon Fire

  • Ignited in July2010 (lightning)

  • Burned 45,000 acres

  • Treatment cancelled

  • 40-80 % of Shingle & Fish sub-drainages burned at moderate-high severity



Twitchell canyon fire2
TWITCHELL CANYON FIRE DRAINAGE

  • Early Oct – Rain storm (bank-full flow) washes ash into tribs and Clear Creek

  • Post-ash sampling: extensive reductions in fish abundance


2011 spring
2011 – Spring DRAINAGE

  • Grade control structures

    • Clear Creek

    • Lower Shingle Creek

  • Little habitat damage from spring run off


2011 august 3 rain storm
2011 – August 3 Rain Storm DRAINAGE

  • Accumulated 0.5 in (Kimberly SNOTEL)

  • Major flooding in Shingle, Fish, and Clear Creeks

  • Topped USGS gauge at lower Clear (max reading 500 cfs)

  • Post-flood estimates of 1500 to 3500 cfs

  • Normal summer base flow of 10 to 20 cfs

  • Major damage to Clear Creek Canyon Road

  • Habitat in Lower Shingle Creek and Upper Clear Creek held up well in flood

  • Destroyed concrete-block fish barrier


  • Each DRAINAGE block weighs 1800 lbs


2011 pre treatment surveys
2011 – Pre-treatment Surveys DRAINAGE

  • Shingle Creek Middle Canyon

2011

2010


2011 treatment
2011 – Treatment DRAINAGE

  • Shingle Creek

  • Clear Creek down to confluence w/ Fish Creek (new barriers)

  • No fish found in Shingle or Clear below Shingle (11.6 mi / 18.6 km)

    • Speckled dace and a few rainbow trout in Clear above Shingle


2011 treatment1
2011 – Treatment DRAINAGE

  • Pole Creek & three tribs

  • Cutthroat found in Skunk Creek (97% BCT)

  • Treated 11.8 mi / 19.0 km


The future 2012
The Future – 2012 DRAINAGE

  • Rotenone treatments

    • Lower Shingle and Upper Clear (second)

    • Pole Creek (second)

    • Upper Fish Creek (first)

  • BCT introduction

    • Upper Clear Creek (sport fish)

  • Sampling

    • Fish Creek – fish, invertebrates

    • Shingle Creek – temperature


The future
The Future DRAINAGE

  • 2013 – Second treatment in Upper Fish Creek

  • Initiate NEPA for BCT restoration in Mill Creek and remainder Clear Creek (incl. barriers)

  • Habitat rehabilitation needed – woody debris felling and riparian planting in Shingle and Fish creeks

  • BCT stocking – not sure when Shingle and Fish will sustain fish (limited source)

  • Introduce other native fish


How has the twitchell canyon fire affected bct restoration in the clear creek drainage
How has the DRAINAGETwitchell Canyon Fire affected BCT restoration in the Clear Creek drainage?

  • Non native fish removal accelerated.

  • Re-establishment of BCT delayed in many areas.
