Visit dates 3/10/19 and 3/18/19
Willard Bay is a man made fresh water reservoir that is 9,900 acres located in Willard
Utah. Willard bay like stated above is manmade, it was separated from the Great Salt Lake in
1964. While traveling to Willard Bay to complete a filled observation I observed that they have
plenty of campgrounds with hookups for water and power in multiple different places. There are
also fire pits pavilions and tables to eat at. There is plenty of parking for visitors, bathrooms, and
out houses as well. Boat docs for boats and jet skis. The amount of boats and jet skiis is pretty
sparse at the time of my visit due to the fact that it was pretty cold out. The majority of the
people I saw there were people who had fishing boats and were fishing off the side of the Lake.
This is easier to do during the colder months when there aren’t a lot of people on the water
scaring fish away. These fishing fanatics also don’t get into the cold water, so that is also
something to mention.
After talking to employees who work here, the told me during the summer it is pretty
normal to see a lot of people jet skiing, boating, paddle boarding, hanging out on the beach
barbecuing, camping etc. The beaches are for people to lounge on while at the Lake while also
having more pavilions for people to eat and have a barbecue at. Behind the pavilions there are
plenty of parking places for vehicles and trucks with trailers. If you look further out into the
water there are water buoys for the “no wake zone”. These buoys mark a no wake zone, what
that means is that once you pass those buoys coming closer to the beach it means that you're
supposed to slow down so it's a safe area for people to swim.
Some of my observations of the field geologic elements are: sediments found are a
variety of size. Rocks large to small, sand and gravel are present on the beaches. There is also a
good amount of vegetation, grass and trees are present along the beach outskirts in the grassy

area and more common within the camping area in the park. I did not see any evidence of lava
flows, or of glacial deposits. There are a few wetland areas present in the no wake zones and
along the beach area. You can't walk through this due to the amount of water that is in these
areas you could end up to your shoulders in water. There's a lot of erosion that has happened
along the beaches. There is a pretty good elevation change along the beach area especially along
the north beach. You can directly see that this has happened over time due to seeing the smaller
rocks towards the steeper incline and larger rocks closer to the water shore line.
If you look at my maps you will see that I have to find 2 different camping areas in the
State Park one on the North end of the Marina and one on the South end of the S Marina. The N
campground has 62 different camp sites most of these do have camping hookups. The South and
campground has 30 camp sites with various hookups. These hookups are there to be a luxury for
visitors so they don't necessarily need an RV or a camper. In the summer months I have heard
that it is common to see lots of tents in this area . When talking to the Rangers I asked further
about people that camping hammocks but they say that that is not allowed to be on the trees due
to damage in trees.

This is the map I drew of where Willard bay
is located in consideration of the Great Salt
Lake, and to be able to see the incredible size
difference. When Visiting Willard bay I got a
sense of how large it truly is. So seeing the
size comparison is pretty spectacular.

This is a close up on Willard bay and where
the different Marinas and campground areas
are. I mostly visited the North Marina due to
the larger space to explore and see a variety of
land.

When I look at the different samples that I have collected I count 11 total samples. These
samples I am looking at are mostly shale , granite, some limestone , and the sand mixture that I
picked up. One thing to note about Willard Bay is that after some research it looks like back in
2016, there was a rock dump that they did to help promote fish growth within the Lake. This
would allow the fish to have a gathering area and a safe place for them to hang out, before this
they did not have very many nooks and crannies for them too explore and stay safe from boaters.
The rock dump that they did had a variety of different sizes of rocks that would allow larger and
smaller spaces for various different sizes of fish. When I look at the post from fox13now.com
regarding this, the Utah division of wildlife resources decided to dump these rocks at the bottom
of the reservoir. They ended up dumping 500 tons of large rocks. They did this by using dump
trucks on a barge and taking it out to predetermined locations along the Lake, and dumping these
loads. This news article states that the division of wildlife resources has been planning this dump
for several years and their plan was to help anglers in their luck for getting fish. “Utah DWR

Below are the attached photos from my visit to Willard bay
Photo 1
This photo is of some of the
mixed rocks that I found near
the side of the road inside
Willard bay. These rocks are
mostly igneous and
metamorphic rocks. I
question if these rocks have
been brought here due to not
seeing this variety in multiple
other places.
Photo 2
This is a large rock within the
campgrounds area of the
North marina. As you can see
from the photo this is a great
example of Granite. The
linear compression is quite
easily seen here.
Photo 3
This is another photo of rocks
in the campground area of the
North marina. This granite
sample is less defined by how
it was formed. The linear
marks here are less obvious
and show signs of
compression from multiple
directions.

Photo 4
This photo was taken in the campgrounds in
the north marina and again a very large rock
that you can see the compression force on this
particular piece over time. This compression
is clear that it comes from multiple directions
Photo 5
This photo is lake side in the North Marina.
Here you can again see the variety of rocks
but most predominantly is granite. Here you
can see how the increasing and decreasing
water depth has made this a rather interesting
ecosystem. Here you can see moss, sand,
large rocks and some weedy grasses.

Another rather interesting observation I had is that in the marinas there are large pieces of
concrete. This is puzzling and again points you in the direction in wondering how many of these
rocks in the landscape have been brought her and dumped in meticulous predetermined locations
to help the ecosystems and wildlife. There are also good sized conglomerate rocks here, they
look like they may have been broke off from the sides of the road and maybe again brought here.
It also makes you wonder if some of this is concrete that may have been dumped in the area
before the Willard bay was cut off from the Great Salt Lake. The different “sand” that I found in
various different parts of the Willard bay is also perplexing. There are lots of different types and
sizes. Some are fine pieces of maybe feldspar or quartz. Some look to be other metamorphic
pieces that have eroded very fine over time.
Some rather interesting observations from my field observations and looking at my
photos, I am definitely drawn to granite rocks. All growing up I have loved rocks but never been
able to fully determine which rocks I love more, here I believe I may have found my answer.
Although there were not a whole lot of other rocks to document, I certainly did not photograph
the cement concrete slabs and the scattered conglomerate rocks.
