CONTRACT & STONE COSTS -

APPROX. $16,000. TOTAL

METHODS EMPLOYED 125 ft of self-adjusting & self-filtering

Longitudinal Peaked Stone Toe Protection {LPSTP}. Mix of DOT heavy & medium graded stone. All protection is on right bank

100 ft of stacked stone wall in the impact zone (upstream end of project)

Curved & vegetated keys on US & DS ends, 1 vegged tieback & key in middle of project

A stone check dam at DS end {did not have enuf stone for an Engineered Rocked Riffle}

A curved kicker (Smile) to form a curved pool Five Single-Stone Bendway Weirs Several transplanted Streamco Willow shrubs Live Siltation, Pole Plantings, & Live Staking

using Streamco & Black Willows, Red Osier & Silky Dogwoods

Rooted-stock Red Osier Dogwood (6 plants)

Looking US at the constructed bypass channel. We plugged the channel, put all flow in the bypass channel, & worked in the dry during

construction.


Silky & red osier cut from an old channel on property

Multi-stem (20 to 40 stems) bushes approx. 14 to 24 ft tall, transplanted as a single clump,

with roots in trench directly behind the LPSTP. Tops of

branches were trimmed & used as Live Poles (6 to 10 ft long).

THE MID-PROJECT TIE-BACK & KEY

{Dig straight trench perpendicular to high flow path, place willow & dogwood poles on US side (so that plants will be in compression against the stone

during high flow events) backfill with graded stone, water in, backfill with soil (overfill for

settling), water in again, seed}

2 years & 8 months after completion. From top bank looking DS. Stream & all stone is hidden by dense veg.


2 years & 8 months after completion. Looking DS @ the apex of the bend. Live Siltation & transplanted willows & dogwood growing well. Nice deep pool to dissipate energy.

2 years & 8 months after completion. Looking DS @ good aquatic habitat by stone (deep-shallow-slow-fast-structure-overhanging veg).


2 years & 8 months after completion. Looking @ the kicker @ the DS end of the deep pool. Note thalweg & willow growth.

2 years & 8 months after completion. Looking @ amazing willow growth in the DS key. Willow was planted up to 14 ft above base

flow water surface elevation, but was planted 4 ft deep & has grown exceptionally well over the last 2+ years.
