Quality Collaborations: Coming Together to Ensure Clean Water for a Healthy, Working River

Friday, February 28, 2020
Embassy Suites Hotel and Conference Center

The Poudre River Forum, an initiative of the Poudre Runs Through It Study/Action Work Group (PRTI), brings together those on the Poudre who farm, deliver clean potable water, drink beer, recreate, and advocate for river health to learn from one another and to explore how we can move from conflict to collaboration. Join us for this year’s event to engage with other Poudre River enthusiasts!

Congratulations to the 2020 Poudre Pioneer Awardees!

Jeff Burley, Ben Loeffler, and Tim O’Hara for their pioneering work on the Poudre River Whitewater Park

Each year, the PRTI and the Poudre River Forum Planning Committee seek nominations for this distinguished award. As part of the Forum, we recognize and honor those who have helped to support making the Cache la Poudre River an excellent example of a healthy, working river.

Thank you to our 2020 Keynote Speaker Josh Goldstein, Director of Bridge Collaborative

Achieving More Together: Fostering Collaborations for Healthy, Working Rivers

From clean water to energy, wildlife to human health—today’s most pressing challenges are highly interconnected. These local to global connections present profound opportunities to partner in new ways to turn shared risks into collective solutions. Drawing on examples from river systems globally, this presentation will focus on three ingredients that can help collaboratives achieve more through their work together: defining the ‘right’ shared problem to solve, using data and analytics to measure progress towards shared goals, and stretching our perspective on who is needed to find effective solutions. While collaboration is admittedly not easy nor a panacea, it is arguably needed now more than ever to create a future in which rivers can support vibrant communities, thriving economies, and healthy environments.

HEALTHY WORKING RIVER: PUZZLES ON THE POUDRE—AN OVERVIEW OF TODAY’S PROGRAM

What are some of those puzzles? How do different interests work together on those puzzles to get water down from the mountains out onto the plains for agriculture and urban use, and how do we keep the river healthy along the way?

WATER RIGHTS PUZZLE ON THE POUDREVideo

  • A Day in the Life of the Poudre River Commissioner—Mark Simpson, Poudre River Commissioner, Division 1, State Engineer’s Office. Where water in the Poudre comes from, who has rights to use it, and how the river commissioner makes sure it goes to the right place at the right time.
  • From Farms to a City: Thornton’s Change Case—Emily Hunt, Water Resources Division Manager, City of Thornton. How a ten year water court had to be surmounted before water purchased from Poudre farmers in the 1980s could be transported south for a growing municipality.
  • Can Carrots, Cattails, and Kayaks Co-Exist under Water Law?—Mike Shimmin, Vranesh and Raisch Law Firm (retired). A Northern Colorado water attorney tells the behind-the-scenes story of the history of legislation that makes it possible for the environment and recreation to have water rights.
  • Bolstering Summer and Winter Flows as Mitigation for Storage—Jerry Gibbens, Northern Water Director of Operations. How seeking federal, state, and local permits to use their water rights on the Poudre to build the Northern Integrated Supply Project led Northern Water to a unique summer and winter flows mitigation approach.
  • Who is Responsible for Poudre Water Quality?—Jerrae Swanson, City of Greeley, Environmental and Water Resources Attorney. With much of the Poudre’s water ending up back in the river after we use it for agriculture and urban needs, who is responsible for overseeing its quality?

ONE HISTORICAL PIECE OF THE PUZZLE: POUDRE HERITAGE ALLIANCE—Karen Scopel – Presentation – Video

THE POUDRE GOES TO SCHOOL – Video

Bilingual eighth graders from Greeley’s Salida del Sol learning about the Poudre and Colorado water issues.

WHAT IS A HEALTHY WORKING RIVER? – Presentation – Video

We will take a look at a video produced by Poudre River Forum committee members Corey Odell and Eric Brown featuring a diversity of perspectives on that puzzling question—drawn from interviews they conducted with folks the length of the river.

Audience Perspectives on “What is a Healthy Working River.” A chance to share our own perspectives with those at our tables on “What is a healthy working river” and then hear from one another about anything that surprised us or broadened our thinking.

POUDRE PIONEER AWARD – Video

On behalf of The Poudre Runs Through It, Robert Ward presented the annual Poudre Pioneer Award to recognize achievements toward the goal of making the Poudre River a premier example of a healthy working river. The 2019 recipients were Loren Maxey and Tom Shoemaker.

KEYNOTE SPEAKER, PROFESSOR EDWARD B. BARBIER, DEPARTMENT OF ECONOMICS, COLORADO STATE UNIVERSITY – Presentation – Video

Barbier’s book, Water Paradox, to be released by Yale University Press in February 2019, is touted as “a radical new approach to tackling the growing threat of water scarcity.” He will share perspectives for us to keep in mind as we tackle water puzzles on the Poudre.

APPLYING CREATIVITY AND COLLABORATION TO ADDRESS THE PUZZLE OF THE LOSS OF WATER FOR AGRICULTURE – Video

  • Regional Storage on the South Platte to Stave off Buy and Dry?Sean Cronin, South Platte Basin Roundtable. What is the South Platte Basin Roundtable and how is the Poudre involved in it? How a study the roundtable is conducting addresses the loss of irrigated agriculture by investigating a regional Ag/Urban/Environmental approach to storing water in times of high flows before it flows out of the state to Nebraska.
  • New Cache Water Marketing Strategy: A Pilot ProjectGreg Kernohan, Ducks Unlimited, and Brett Bovee, WestWater Research. How New Cache la Poudre Irrigating Company is working with Ducks Unlimited and others to pilot a unique water sharing strategy, with funding from the Beueau of Reclamation.
  • Larimer County Ag Advisory Board’s Take on the Need for Ag/Urban Water DialogueZach Thode, Manager, Roberts Ranch. The need for cities, towns, and ditch companies to work together to ensure reliable deliveries in both wet and dry years for both urban and Ag needs.

WHAT’S THE [EVOLVING] PICTURE ON THE PUZZLE BOX LID? – Video

What are the looming challenges we face on the Poudre, and are there ways we might begin to look at them differently than in the past? A panel of experts will address the following questions and then participate in a facilitated dialogue between themselves and then the audience:
