Emigration Creek Overview
-
The Emigration Creek Watershed covers about
17 sq. miles. 1/8 mile through Westminster
Campus.
-
40% owned privately, 33% owned by Salt
Lake, and 27% is National Forest land
-
Emigration Creek serves great purpose to its
surrounding area in Salt Lake and Sugarhouse
by providing a source of water and minerals
within the watershed.
-
The watershed is responsible for maintaining a
viable cyclical system of energy in order for life
to be sustainable.
Issues
1. Erosion: banks are steeply eroded compromising
the safety of nearby structures along with the
health of the ecosystem.
1. Pollution: ineffective storm drains from parking
lot pollutants into creek causing potential
eutrophication and posing threats to both
vegetation and macroinvertebrate populations.
1. Littering: build up of debris and trash throughout
branches and low-depth areas.
Bank Stabilization
◈ Bank Shaping
Re-grading streambanks to a stable slope
◈ Planting Vegetation
Placing topsoil and other materials needed for sustaining plant
growth, and selecting, installing and establishing appropriate
species.
◈ Brush Mattress
Combination of live stakes, live fascines, and branch cuttings
installed to cover and physically protect streambanks,
eventually to sprout and establish numerous individual plants.
◈ Dormant Post Plantings
Planting of cottonwood, willow, poplar, or other species
embedded vertically into streambanks to increase channel
roughness, reduce flow velocities near the slope face, and trap
sediment.
Trench Drainage System
Install a shallow basin drainage
system, which runs over a long
distance. Designed to collect and
divert water at a lower and more
appropriate location to avoid
contamination of the creek.
Macroinvertebrates
Hire biologist to interpret the
data we collected on
macroinvertebrate richness
and determine which
species of macros should
be supplemented to the
current ecosystem and in
what quantities.
Decrease Human Disturbance
Signage:
several professional looking signs around the creek area will remind students, staff, and other foot traffic
that the creek is in a fragile state and should be respected and kept clean.
Fencing:
certain areas near high erosion transects will be fenced off and access to public will be restricted in order
to give the bank stabilization process adequate time to be effective.
Posters:
the remaining budget will be spent on creative laminated posters to put around campus and the
sugarhouse area urging people to take care of the creek. Additionally, the posters will contain information
regarding bi-monthly volunteer times to keep the creek in good health.
