Kasprak, Hough-Snee, Camp & Jensen) decided to take a class project in a River Styles short course to compare various stream classification approaches to a whole new level. They published their findings in PLOS-One this week and Utah Public Radio and USU Today both picked up the story.
article from Business Insider give a brief overview of salmon restoration work in the PNW. Specifically focusing on IMWs. Bridge Creek gets a mention, and Steve Bennett has a memorable quote:"It's OK if natural beavers join in on the fun," said Stephen Bennett, a research associate of watershed sciences at Utah State University who is involved with that and other studies." The article was in response to a pair of recent papers on Intensively Managed Watersheds and Adaptive Management led by Steve Bennett and just published in last month's episode of Fisheries Magazine.
On Saturday January 23rd, Elijah Portugal from the FHC was interviewed again by Jennifer Pemberton from Utah Public Radio's excellent program on water issues in Utah, The Source. The short (~5 mins) follow up interview was in regards to the Walmart beaver mitigation project, where Elijah filled Jennifer in on the current developments at the Walmart beaver ponds since last April when the original interview was conducted. In summary, we successfully installed two pond levelers upstream of the two main beaver dams within the wetland area in Spet (2106) to control flooding, and the devices have been successfully working since then. We also used fencing and abrasive paint to prevent the unwanted harvest of ~6 trees. Many thanks again to Jennifer pemberton from The Source and everyone else that made this project a success!

FHC , ELR , and Anabranch Solutions have been working for the past year with Dan Miller from the Bear River Watershed Council, to help the South Logan Walmart and the City of Logan develop an adaptive beaver management plan. The plan by Portugal et al. (2015) is quite simple - instead of relying on traditional approaches of lethal control to mitigate the potential flooding and tree harvesting impacts of beaver, it proposes simple 'living with beaver' strategies. The plan draws on long-standing techniques of 'living with beaver mitigation strategies' (e.g. Beaver Solutions), and codifies potential actions to different scenarios in to a simple, common sense approach to mitigating the nuisance problems beaver pose.
The efforts culminated on October 12 in the installation of a couple of pond levelers. Much to our surprise, this relatively small side project we undertook as a volunteer effort garnered significant media attention. Below is a partial listing of some of the media outlets that picked up the story. FHC's Nick Bouwes, Elijah Portugal and Scott Shahverdian are all featured.

The Grand Canyon Trust has just released a new 13-minute video “Beaver: Back to the Future,” featuring ET AL's own Nick Bouwes. It also includes four Forest Service employees, and a retired Regional Forester who praise the power of beaver to beneficially restore and manage national forest water flows in the face of climate change.
Filmmaker Sarah Koenigsberg’s camera captures three processes by which beaver have recently been able to re-enter creek systems in Utah, Oregon, and Washington to work their dam magic.
New ‘Structure-from-Motion’ Sandbar Surveying Method used by Youth Citizen Scientists in Grand Canyon National Park
“participating in citizen science has widen my perspective and understanding
of Grand Canyon and why it is vital to protect it.”

Youth citizen scientists collect images and ground control data
with 'structure-from-motion' sandbar surveying method
Earlier this summer, Utah State University graduate student Becca Rossi rafted and surveyed sandbar topography along the Colorado River with a group of youth citizen scientists from the Grand Canyon Youth program. Her team for this trip consisted of 24 youth, 2 youth coordinators, 6 river guides, and 2 other scientists.
During the two weeks of surveying, the group rafted over 225 river miles of canyons in the Grand Canyon National Park (GCNP) to collect data. Both USU and the Grand Canyon Monitoring and Research Center (GCMRC) will use this data to monitor and record changes in size and stability of sandbar deposits along the Colorado River downstream of Glen Canyon Dam. Sandbars provide habitat for terrestrial and aquatic species, campsites for river rafters and scientists, and an aeolian sediment source for the preservation of archaeological sites.

The Glen Canyon Dam Adaptive Management Program has monitored sandbar depletion for more than twenty years through GCMRC. Annual topographic monitoring has focused on sandbar response to high flow experiments (HFEs) released from Glen Canyon Dam at 45 sites throughout GCNP. The Paria and Little Colorado Rivers are the two main sand sources downstream of the dam. With enough monsoonal rain, tributary sand is stored on the channel bed and is then mobilized downstream by the HFEs. These environmental flows aim to maintain and build sandbars within GCNP. Annual monitoring campaigns survey sandbar topography using a total station setup and repeatable control network.
There are roughly 500 large sandbars distributed over the 225 miles of the Colorado river throughout GCNP. The question remains, if the 45 sandbar monitoring sites are representative of the total sediment budget in response to the modified
Map* of the Colorado River downstream of Glen Canyon Dam with
locations of the 45 annual sandbar monitoring sites (red triangles).
Sandbar site extension provides an option to test the representation of the 45 monitoring sites, but is costly and time-consuming with the current surveying method. 'Structure-from-motion' photogrammetry (SfM) is a new surveying method that will potentially provide a cheaper and faster way to extend the topographic sandbar survey in GCNP. The method consists of collecting overlapping, oblique imagery with consumer grade cameras mounted on 16 ft poles. To ensure repeatability of the survey, 10-50 ground control points are surveyed across the sandbar surface with a total station. Post-processing of the data consists of creating 3D models of the surface topography using robust pixel-matching algorithms.

The youth citizen scientists collected data at 12 different sandbar sites distributed across Marble and Grand Canyons. Images were taken every 10-15 feet along upstream, downstream, and circular transects on the sandbar surface. Repeat surveys were used to test the variability in camera angle and image spacing between youth crews. While in the field, youth were able to see 3D visualizations of the sandbars they surveyed with the SfM software Agisoft Photoscan Professional. The youth also collected ground control point data with the help of a surveyor, and handheld images from across, behind, and in front of the sandbars.

In addition to teaching the youth emerging scientific survey methods, Becca’s research goals included teaching them about fluvial geomorphology in Grand Canyon, and the impacts of Glen Canyon dam on the downstream environment. She also hopes to evaluate the feasibility of using citizen science in future monitoring of sandbars. This is the second of three field work trips that Becca will conduct in GCNP during her time at USU to develop and implement a SfM surveying protocol.
One of the youth on the trip said “participating in citizen science has widen my perspective and understanding of Grand Canyon and why it is vital to protect it.” He especially enjoyed the scientists, saying that “they knew how to have fun and to get the projects done,” and that he “really enjoyed learning about the software that would create the beach models.”
Becca is currently working on her Master’s degree in Watershed Sciences with Dr. Joseph Wheaton, Dr. Paul Grams (GCMRC), Dr. Daniel Buscombe (GCMRC), and Dr. Jack Schmidt (USU). At USU, she is specializing in fluvial geomorphology. This interest has brought her to USU and specifically the Colorado River downstream of Glen Canyon Dam where she is currently working on a thesis investigating sandbar dynamics in response to high flow experiments in Marble and Grand Canyons using emerging 'structure-from-motion' photogrammetry techniques.
Of her experience, Becca says, “the public is often disconnected to science and its importance, and citizen science is a way to bridge this gap. Citizen science is especially important for protecting environments from negative anthropogenic impacts. This experience has not only aided the progress of developing an SfM surveying protocol, but has aided me to contextualize my research into the bigger picture of disseminating scientific knowledge to the public, and more importantly to youth.”

A recent publication in Logan's Herald Journal - Bridgerland Edition on June 28, 2015 featured our favorite furry friend. The article, titled "As Busy as Beavers" was included in the Wild Things issue celebrating Cache Valley's living treasures. Nick Bouwes provided details on the work of the Fluvial Habitats Center, and projects between the south Walmart and the Bear River Watershed Council. He also said that a recent count conducted on the Logan River and Blacksmith Fork draining areas found over 1,100 beaver dams.
Moonshine Wash, Lower San Rafael River
Like many desert rivers, the San Rafael River in Price County, Utah has become degraded largely through human-induced alteration of the natural hydrology by over-allocation of water. The magnitude and duration of spring snowmelt floods has been diminished since the early 1900s while monsoon floods continue to deposit large quantities of sediment within the channel, floodplain, and along the channel margins. The altered hydrograph has left the lower San Rafael River in a transport limited condition where the amount of sediment supplied to the channel exceeds the river's ability to transport the sediment out of the system. This dynamic, coupled with dense populations of invasive tamarisks along the channel margins and floodplain, has led to channel narrowing and vertical incision, leaving much of the lower San Rafael disconnected from its historic floodplain. The incised condition, along with the lack of floodplain connectivity, has degraded the quality of instream and riparian habitat leading to a reduction in native fish populations, and a lack of cottonwood and willow recruitment on the floodplain.
A large collaborative restoration effort was developed with the primary restoration goals to: 1) improve native fish populations, specifically for three native fish species listed as sensitive species (e.g.,flannelmouth sucker (Catostomus latipinnis), the bluehead sucker (Catostomus discobolus), and the roundtail chub (Gila robusta)), 2) improve instream and riparian habitat and, 3) use adaptive management/experimental approach to restoration planning, implementation, and monitoring in order to learn as much as possible from this project to inform future restoration efforts on similar desert rivers. The project is a collaboration between the Bureau of Land Management, the Utah Division of Wildlife Resources, the United States Geological Survey, and Utah State University's Fish Ecology Lab, Fluvial Geomorphology Lab, the Utah Water Research Lab, and the Fluvial Habitat Center. The project consists of: 1) large-scale tamarisk removal from the banks and floodplain to allow for natural river migration and a transition to native riparian vegetation, 2) gravel augmentation to increase the complexity of instream habitat and learn about sediment transport dynamics within the lower San Rafael, 3) addition of boulders from the valley wall margins where the river naturally contacts the valley margin, and 3) use beaver and beaver dam analogs to improve instream and riparian habitat.

Beaver are naturally present in the lower San Rafael River, but the narrow incised condition and lack of suitable riparian vegetation prevents their dams from persisting for very long and likely limits the size of their population. The developers of the restoration plan for the San Rafael River recognized the critical role that beaver have historically played in structuring and maintaining a healthy riverine system and wanted to 'Partner with Beaver' to restore physical and ecological processes within the lower San Rafael River. This project is the first of its kind to use Beaver Dam Analogs (BDAs) in a primarily sand-bedded desert river. The Fluvial Habitat Center was contracted to develop a large scale pilot restoration design to test the effectiveness of using BDAs to improve instream and riparian conditions and beaver habitat within the lower San Rafael River. Dr. Joe Wheaton, Dr. Nick Bouwes, Wally MacFarlane, and Elijah Portugal are responsible for conducting this project for the Fluvial Habitat Center.
