Using recently developed — and in some cases, still
developing — tools for calculating the ecological
uplift of restoration projects, we are advancing a new
framework for communicating the value of our work.
Using this new framework, we quantified most of
our work in 2012 with regard to ecological uplift
and issued our first Uplift Report. In 2013 we
quantified new projects with the calculators, and
evaluated a new method to determine river health.
The process of calculating the uplift benefit of our
actions helps hone our organization’s focus on
delivering the best ecosystem outcomes for our
invested dollars and provides collaboration with
the restoration community to evaluate and test
chosen quantification tools. We understand that
for these uplift measurements to be used on a
S
ince the passage of the Endangered Species
and Clean Water Acts, there have been
many successful river restoration projects
along with great leaps in the engineering
and design of river restoration solutions — all driving
toward improving water quality and aquatic habitat.
Over the last decade, the restoration community has
been working to develop and implement methods
for economically and physically quantifying the
effects of long-term restoration actions within a more
accountable framework.
The Freshwater Trust has traditionally evaluated
and reported on projects in terms of dollars spent,
trees planted, gallons of water restored instream
or acres of floodplain reconnected. In 2012, our
approach evolved to measuring ecological benefit.

Why quantify?: The application of new tools and methods to
accurately quantify the ecological benefits of conservation actions
provides numerous benefits to practitioners, landowners, regulators,
conservation grant makers and policy makers charged with
managing our natural resources and environment.
Grants and other investments can be targeted based on modeled
ecological benefits (outcome-based) – potentially a more precise
method than the traditional evaluation of proposed actions
(process-based).
Landowners, particularly farmers, ranchers and foresters, can
better determine current (pre-project) conditions and accurately
track uplift (post-project) from conservation on their lands.
Practitioners can improve project design and associated
monitoring efforts.
Regulators could better track performance towards water quality
or species targets within a watershed, by accumulating quantified
results from projects over time.
Lawmakers and other policy leaders could use quantified
results from projects on the ground to better guide public
investment in conservation.
national scale to predict the effects of our actions
on true river restoration, we require the buy-in and
support of the regulatory, restoration and regulated
communities. Sometimes this involves automation
of the calculations we use regularly for efficiencies of
scale, and sometimes this involves evaluation of new
methods of measuring impact in a holistic manner.
What do we mean by ecological uplift? Simply put,
“uplift”refers to the environmental gain of a project
— the quantifiable environmental benefit of the
restoration actions we take. For example, consider
planting trees next to a stream. In the past, we have
focused on restoration inputs —trees planted or
habitat structures created. But not all parts of a
stream are created equal in the amount of ecosystem
services they provide. Using new tools and science,
we now employ an outcome-based process for our
actions (focusing on where the planting of trees has
the most benefit and the value of this benefit). For
example, we can now model the solar radiation that
will be blocked by mature trees, preventing river
waters from heating up to the detriment of cold
water species like salmon and steelhead.
Quantifying the benefits of restoration projects
in this way can provide a more robust picture
of a project’s ecological value. In fact, we are
now doing these calculations on projects before
implementation to determine potential ecological
uplift prior to committing significant resources
to a project. We do this to ensure we implement
restoration actions that achieve the most benefit for
the freshwater ecosystem.

iparian shade provided by streamside
vegetation blocks the sun’s rays from
reaching the surface of the water, reducing
the amount of thermal energy entering
the river. In effect, this shade prevents the water
from heating up. Anadromous fish, such as salmon
and steelhead, are extremely sensitive to water
temperature; therefore, healthy riparian buffers help
ensure healthy fish habitat.
Shade-a-lator is a module of Heat Source, a stream
assessment tool used by Oregon Department of
Environmental Quality (ODEQ). It was developed in
1996 at Oregon State University in the Departments
of Bioresource Engineering and Civil Engineering.
ODEQ currently maintains the Heat Source
methodology and software development.
Using pre-project data (see sidebar for model
inputs), Shade-a-lator calculates the current load
of solar radiation reaching the surface of a stream.
Once vegetation is planted, Shade-a-lator predicts
the new load of solar radiation reaching the stream
based on the new vegetation’s shading capacity at
maturity. The difference between pre-
project and post-project solar loading
represents a project’s uplift in terms of
solar radiation avoided by streamside
riparian vegetation. Shade-a-lator
expresses this uplift in energy units of
kilocalories per day. Once we have this
calculation, we can determine which
restoration sites will most benefit from
riparian restoration.
Shade-a-lator has been in use and
ongoing development for more than a
decade. With The Freshwater Trust’s
projects, its refinement will continue.

fence building to exclude livestock, to changed farm
practices like improving irrigation methods.

major water quality concern across the
United States is the abundance of nutrients
such as nitrogen and phosphorus in our
freshwater systems. Too much nitrogen
and phosphorus promotes excessive plant and
algae growth, choking out other aquatic species.
Large sediment loads that carry these nutrients
can also harm aquatic systems. They can settle
into streambeds and fill in the spaces between the
rocks and gravel — spaces that are essential for
salmonid spawning.
Nationwide, runoff from farming and ranching
operations contribute large loads of nitrogen and
phosphorus. The Freshwater Trust is working to
measure the benefit of conservation actions that
limit these inputs while maintaining productive
agricultural lands.
The Nutrient Tracking Tool (NTT) is a sophisticated
modeling tool that allows the user to create a
detailed scenario of on-field agricultural practices
(see sidebar for model inputs). NTT models the
agricultural practices and then estimates the annual
nutrient and sediment loads that occur as a result
of these actions. NTT can model a wide assortment

project conditions of a field to modeled conditions after
restoration or changed farm practices.The difference

we have this calculation, we can assess the impact of
site-level restoration as a component of a basin-scale
water quality problem.

Field staff take
a flow measurement
to help determine the
temperature benefit for
restored flow.
ncreasing river flow can buffer water
temperature and increase velocity through
a stream reach. Higher velocity can limit the
water’s exposure to local solar impact, keeping
the water from warming. Additional temperature
benefits can be achieved if the increased flow is
cooler than the water in the existing stream reach.
The Water Temperature Transaction Tool (W3T)
uses river and landscape characteristics to estimate
hourly solar radiation and overall heat loss or
gain from a water body. W3T also incorporates
temperature and flow inputs provided by tributaries

and meteorological information. From these inputs,
W3T calculates temperature changes in a river reach.
W3T is based on a steady flow approach requiring
pre-project data (see sidebar for model inputs). W3T
models water temperature based on energy transfer
to and from the water across the air-water interface
and bed-water interface. W3T also accounts for
transport of heat energy in the downstream direction.
Water temperature reduction from increased flow can
be determined by subtracting pre-project conditions
from modeled conditions after flow has been
restored. The difference in water temperature
represents the temperature improvement
(uplift) from restoring flow to that reach. Once
the temperature impacts of flow are quantified,
flow restoration can be used as a tool to directly
address and account for water temperature
as a limiting factor that affects the survival of
threatened and endangered fish species.
National Fish and Wildlife Foundation
contracted with Watercourse Engineering to
develop the W3T model, with funding from
USDA Natural Resources Conservation Service.

The Stream Function
Assessment Methodology
is being developed for Oregon by ESAVigil-Agrimis
and Skidmore Restoration Consulting, LLC with
funding from US Environmental Protection Agency.
The tool is designed for use in Oregon’s stream
compensatory mitigation program being developed
by Oregon Department of State Lands, US Army
Corps of Engineers, US Environmental Protection
Agency and Willamette Partnership.
The Stream Function Assessment Methodology
is undergoing beta testing, including extensive
field testing throughout Oregon in 2014. While
the tool is still under development, early adoption
enables The Freshwater Trust to calculate the 2013
level of function for our stream restoration sites.
T
he Stream Function Assessment
Methodology was designed as a rapid
assessment that evaluates stream
functions and values. Stream functions
are the processes that create and support healthy
stream ecosystems; functions include flow
variation, sediment mobility and nutrient cycling.
The Stream Function Assessment Methodology
defines stream values as the ecological and
societal benefits that the stream functions provide.
The Excel-based calculator generates scores for
hydrologic, geomorphic, biologic and water quality
(chemical, nutrient and thermal) functions as well
as the importance of each of those functions.
Inputs for the tool are collected both in the field and
using online resources (see sidebar for model inputs).
The methodology considers stream and riparian
area characteristics along with the ecological and
societal benefits of that stream in generating the
functional assessment.The output of the tool is a
score between 0% and 100%, rating the function and
the value of the stream.This score is multiplied by the
linear feet of stream affected to generate functioning
linear feet of stream. By calculating the difference
between functioning linear feet of stream before and

T
he Salmon Calculator is designed to
quantify ecological changes that directly
impact salmon habitat through modeling,
on average, how well a given stream reach
supports salmon. Based on the inputs of physical
characteristics of the stream and terrestrial
areas (see sidebar for model inputs), the Salmon
Calculator measures the ecological functions of
a stream with regard to its ability to create and
maintain salmon habitat. The Salmon Calculator
then consolidates those ecological functions into
one salmon habitat score. The score is a percentage
of functional habitat per linear foot of stream, which
is recorded as weighted linear feet. Once we have
this calculation, we can
understand the impact
of our projects on the
habitat needs of listed

Conservation Service grant project managed by

Salmon Calculator began as part of the Oregon

was further refined by Parametrix, Inc.
The Salmon Calculator has been valuable in
helping us improve our understanding of how
instream actions affect species health, but a more
robust stream assessment tool is being developed
that will further improve our ability to estimate
stream function for salmon. (See Stream Function
Assessment Methodology, previous page.) To
enable ongoing evaluation of the uplift of our prior
actions, however, we continue to use the Salmon
Calculator into 2013.As demonstrated by the shift
from the Salmon Calculator to the Stream Function
Assessment, the restoration community is still
determining the best measure of stream ecosystem
health for salmon. In Oregon right now, three
standards of measurement are used: NOAA’s Habitat
Equivalency Analysis, the Columbia River Basin
Federal Caucus’Survival Benefit Unit and the Stream
Function Assessment. In 2014,The Trust is engaging
with this community to evaluate and adopt the most
practical measure of stream health for salmon.

Rudio Creek in central
Oregon restores this
stream to its historical
floodplain.
Returning a Stream to its Natural State: Historic land use practices
moved Rudio Creek to the edge of its floodplain to facilitate agriculture.The
shorter, straightened channel increased stream energy which disconnected the
channel from its floodplain, increased substrate size and reduced the number and
complexity of pools. Returning Rudio Creek to its 1946 historical alignment will, over
time, restore self sustaining habitat conditions that benefit salmon and steelhead.

Increase instream flow. The Freshwater Trust
entered an agreement with the landowners on Rudio
Creek that requires their diversions from Rudio
Creek to stop when flows at the mouth drop below 2
cubic feet per second or on July 1, whichever occurs
first. This contractual obligation protects late-
summer flows to the mouth of Rudio Creek, which
historically ran dry.
n 2012,The Freshwater Trust reconstructed
the historic channel of Rudio Creek to
restore its natural flow and habitat. In 2013,
The Freshwater Trust implemented several
additional restoration elements complementary to
the major restoration activities completed in 2012.
These elements are designed to ensure the site
continues on its restoration trajectory and increases
habitat for juvenile spring Chinook and summer
steelhead. 2013 work included construction of
off-channel ponds with side channel connections
to Rudio Creek, and livestock exclusion fencing and
hardwood plantings to promote riparian recovery.
Promote riparian vegetation via hardwood
planting and livestock exclusion fencing. Riparian
vegetation is intended to provide channel stability,
