The Water Connection (TWC) is excited to announce the pilot of an instream trash removal device-- the Nautilus! This half-scale prototype will passively collect trash along the north side of the Cherry Creek between Blake Street and Market Street. Nautilus is being serviced regularly by Mile High Flood District and ArborForce to collect valuable information regarding the device’s function and what types of debris are being collected. Other partners for this pilot include ClayDean Electric, who built this version of Nautilus, as well as Denver Parks and Recreation and Naranjo Civil Constructors.
“Like many urban areas, keeping trash out of our waterways in Denver has been a constant challenge” said Devon Buckels, Director of The Water Connection. “Every year, local non-governmental organizations and the Mile High Flood District spend $1.5 million removing trash from the South Platte River by hand, one piece at a time. There has to be a better solution. This is 2020!”
The concept for the Nautilus design was created by two students at Metropolitan State University of Denver, Mara Maxwell and TJ DiTallo, as part of TWC’s Clean River Design Challenge (CRDC) held during the 2015-2016 academic year. CRDC is a yearlong competition that challenges teams of undergraduate students to design and build a scale model of a device to be placed in a waterway in Metro Denver to remove trash and debris. Along with being efficient and effective, these devices also have to meet numerous other criteria: they must not negatively impact the flood plain, they must be safe for recreational users and wildlife, and they must have an educational and/or art aspect to the design to engage passersby in the community. Trash in our waterways is not only an eyesore, but it can also harm wildlife and degrade water quality. TWC is also pursuing other trash capture approaches, such as storm drain filtration devices, for collecting trash before it enters our rivers and streams. The 15 storm drain filters in Metro Denver collected 3,960 pounds of pollutants in less than two years. Next time you are biking or hiking the Cherry Creek path, stop by to visit the Nautilus!

It is almost time to uncover our gardens from last year to prepare for spring and summer bounty. Sometimes though we can’t do it on our own. Often, it is our FBIs that help break down old plant material to prepare for the new. We aren’t talking about law enforcement though… SPREE FBIs are decomposers and are also known as Fungi, Bacteria, Insects and Scavengers. These are the FBIs we learned about on Monday’s holiday camp.
We started our first activity by planning a pizza- each camper added their favorite topping to our pizza. At the end, we realized that we forgot one FBIs topping- mushrooms. Mushrooms belong to the fungi kingdom along with other familiar organisms like lichen and yeast. We continued learning about fungi with some yeast experiments, mushroom art, and mushroom dissection!
Bacteria is a harder FBIs to study because the organisms are microscopic and cannot be seen with the naked eye. So we used UV lights to study some camp surfaces. While the UV did not illuminate just bacteria, it did give us an idea of how “dirty” some surfaces were- and the dirtier the surface, the likelihood of both good and bad bacteria is high! We did some experiments comparing cleaning supplies- we cleaned a camp mat using antibacterial wipes, vinegar, and soap & water to determine the best way to keep surfaces clean for the long term is soap and water.
We jumped into insects during our critter crawl. This jumping did not include jumping into the water- as we did our critter crawl on land due to cold weather. Teachers used a tool called a kick net to scoop macroinvertebrates from the River and bring them onto land where campers could sort and count the macros by whether they were a decomposer or not. Though crawdads aren’t insects, they are scavengers and we caught several along with some scuds, water boatmen, and mayflies.  We wrapped up the day with a group activity about scavengers. Scavengers are animals from many different families that all have one thing in common- they eat dead things! Some examples of scavengers are eagles, vultures, crawdads, and coyotes. We focused on our birds of prey scavengers, and created our own balancing scavenger birds. Campers were then challenged to balance their birds while walking through an obstacle course. We were impressed with all the different birds that were created- and the balance of their handlers! Despite the cold weather, we had a great time learning and playing during SPREE’s FBIs holiday camp. We look forward to seeing you again down by the River!
We were happy to see all our campers navigated their way to SPREE HQ last Friday for camp! Some campers admitted they used GPS devices to navigate to camp while others said they knew the way without any help. By the end of the day, all campers were more confident in their ability to read and use navigation tools like maps & compasses.
Our first activity we focused on an old tool of navigation- the compass! Compass tools have sophisticated over the centuries, but they all work because of the magnetic pull at the earth's poles. We experimented using a compass, practiced cardinal directions though a game of Compasball, and even attempted to make our own compasses using water, leaves & a sewing needle!
Our second activity was about reading and making maps. We first compared maps to determine the most important features that all maps should have: title, compass rose, scale, & a key. We found our South Platte River on a map of Colorado and traced it from its beginnings west of SPREE HQ, through its journey in and out of Colorado. We wrapped up this activity by making our own maps of SPREE HQ where we learned how maps of the same place can vary based on cartographer.
Though it was a little chilly, we still did critter crawl for our third activity. A favorite activity by both campers and teachers, we modified our critter hunt to keep our feet DRY! Teachers used a kick net to scoop macroinvertebrates from the River, and then carried them to land where campers could easily sort the critters without needing to get into the water. We found 8 crawdads despite the frigid water!  We wrapped up Mapping Our Way with a group introduction to geocaching. SPREE created a geocache that will be placed when the ground thaws. We used tablets to investigate other geocaches in the area, and found that our created SPREE geocache would be the only one at Johnson Habitat Park! We then played a game reviewing cardinal directions that also challenged campers to solve riddles. What a fun day at SPREE HQ. We look forward to seeing you again down by the River!
Parthenogenesis is a reproductive strategy that allows reproduction without fertilization - in short, it allows members of a species to reproduce without a partner! Below are a few of these magnificent critters to celebrate this Valentine’s Day:  Marbled Crayfish First discovered in Europe, this cousin to the Rusty Crayfish found in the South Platte River was the first crustacean detected to reproduce asexually. Researchers believe this species of crayfish, also known as the marmorkreb, to be entirely female. Scientists believe this species is only about 25 years old and resulted from a genetic mutation when two Slough Crayfish mated.  Whiptail Lizards Another all-female cohort is the Whiptail Lizard. Whiptails can be found in the Southwest United States, Mexico, and South America. The only know unisexual reptile, whiptails evolved from hybrids of other species of lizards. To maintain genetic diversity within the species, they begin their reproductive process with twice the number of chromosomes as their sexually reproducing relatives!  Goblin Spider - Triaeris Stenaspis This subspecies of Goblin Spider (aka Oonopidae) is thought to be parthenogenetic, as no males of the species has ever been found. This particular Goblin Spider resides in tropical & subtropical areas all over the world. Though unconfirmed that it is entirely parthenogenetic, it has proven able to reproduce asexually under lab conditions. Sources:
Last weekend, Greenway Leadership Corps (GLC) adventured to Vail Mountain Resort to try our hands at snowboarding. We left Denver at the crack of dawn to make our way up into the high country, where most of Colorado’s water starts. It was amazing to see how much an environment can change in just a few short hours’ drive. Big thanks to Environmental Learning for Kids (ELK) and SOS Outreach for providing the transportation, gear, and snowboarding instruction for our GLC crew!  Perfect weather (sunny and warm) kicked off a day full of new experiences, overcoming challenges, and lots of laughs! Learning snowboarding can be a frustrating endeavor, even amidst beautiful mountain scenery. At the beginning, most of us were constantly falling. Luckily, Vail provided us with some great instructors; they gave constant encouragement and tips to help all of us improve. It was awesome to see the students showing resilience and perseverance when facing a challenge. As the day wore on, all the hard work the GLC crew put paid off with some serious shredding down the mountain.
Thanks to all the students who came out to try snowboarding with us (including some folks from ELK)! We look forward to working with SOS Outreach and ELK again soon.   The Greenway Leadership Corps took advantage of Colorado’s sunny winter weather last week, and went ice skating at the Downtown Denver Rink at Skyline Park! A big thanks to The Downtown Denver Partnership for providing an outdoor opportunity for community and fun during these winter months! We were joined by many familiar and new students, including an outdoor leadership student group from Westminster High School!   Greenway Foundation Supporters and Advocates: Colorado Trout Unlimited (CTU) and The Greenway Foundation (TGF) are pleased to announce that the Colorado Trout Unlimited (CTU) 2020 River Stewardship Award is being awarded to TGF’s Executive Director, Jeff Shoemaker. As Executive Director of The Greenway Foundation, Jeff has led a true revival of Denver’s urban waterways for close to four decades. From promoting parks and responsible development along greenways, to raising funds for the Chatfield Reservoir environmental pool benefitting South Platte River stream flows, to developing environmental education programs that engage thousands of Denver youth every year, The Greenway Foundation, under Jeff’s leadership, has embodied the concept of river stewardship for an urban community. The CTU River Stewardship Award will be presented during the course of CTU’s 2020 Stewardship Gala on Thursday evening, March 5, 2020. This annual gathering at Mile High Station in Denver is a fun evening of food and drink and raising funds for Colorado TU’s conservation work around our beautiful state! If you are interested in being a part of this special evening honoring Jeff and TGF, the CTU Stewardship Gala regularly sells out early! Learn more by visiting this link. We hope to see you on March 5, 2020 as we celebrate Colorado’s rivers and fisheries and honor Jeff Shoemaker as CTU’s 2020 River Stewardship Award winner!  
What started off as a chilly morning, only got colder as the day went on. That didn’t stop our campers from diving deep into the world of Denver’s Urban Animals! We had a packed day of fun and learning at SPREE HQ last Monday during our holiday camp.
The day started with our mission from Chompers who told us we would learn about nocturnal nature visitors, water fauna, and pesky park dwellers. The first activity was on a nocturnal animal….  Our Greenway Leadership Corps (GLC) adventures took us to Ft. Collins to discover what Colorado State University (CSU) and their Environmental Learning Center (ELC) has to offer college students. The ELC is located on 300 acres of woodland and prairie, and works to connect people with nature through environmental education. We were lucky to have two CSU students as our educators–Aaron and Claire–who are studying at the Warner College of Natural Resources at CSU. We started the day with a test of trust in our teammates and our leadership skills. After lining up along a rope we placed blindfolds over our eyes and set out to guide each other along a natural challenge course. After our daunting teambuilder concluded, we were ready to use our sight to help us conquer the next challenge. The team at ELC had already placed flags around the woods and gave us a map with the locations of the flags, a compass, and a lesson on orienteering. When the whistle blew, all teams ran in opposite directions in search of orange flags. Some teams used their new orienteering skills while others leaned on good luck! After our adventures through the woods we learned about and practiced stewardship by picking up trash and pulling up mullein, an invasive species found throughout Colorado. Mullein can overtake and displace native plants, and will take over areas when left unattended.
