South Platte Regional Opportunities Working Group (SPROWG) Established

Significant discussions and initial grants have been made for an ambitious plan for water storage and reuse plans on the South Platte watershed.  Authorized by Colorado HB 16-1256 a South Platte Storage Study has been completed and organizing efforts are underway to find ways to recapture 300,000 Acre-feet per year of water that is flowing out of the state to Nebraska.

The South Platte Regional Opportunities Working Group (SPROWG) has been established and has received grants of $350,000 from the Metro and South Platte Basin Roundtables and the Colorado Water Conservation Board.  Organizations participating in the group include South Metro Water Supply Authority, Denver Water, Aurora Water, the Northern Colorado Water Conservancy District, the St. Vrain and Left Hand Water Conservancy District, the North Sterling Irrigation District and the Lower South Platte Water Conservancy District.

The concept includes 175,000 acre-feet of new water storage in three locations near Henderson, Kersey and Snyder and the construction of a pipeline back to the South Platte River north of Denver.

The costs and environmental impacts are being assessed.

Boulder County Asserts Land Use Approval Authority over Gross Reservoir Expansion Plans

Boulder County has asserted the authority to conduct a land use review of the proposed Moffat Collection System Project.  In a letter dated October 12th, 2018 Denver Water requested an exemption from current land use codes.  In a letter dated October 22nd, 2018.  Boulder County denied this request and stated that Denver Water will need to obtain a new land use permit prior to undertaking any work on the project.

The impact of this action is significant.  Denver Water was ready to proceed with the project, but that will not be possible without either approval from Boulder County or litigation.

Dam Failure in the Mekong River Watershed

On July 23rd the Xe-Pian Xe-Namnoy dam a $1B hydroelectric project funded by South Korea floods villages in Laos and Cambodia and illuminates the dangerous water politics and policies along the Mekong river.  Dozens dead, hundreds missing and thousands displaced.  

Lao government to suspend all new hydropower dam contracts.

Hoover Dam as a $3B Battery?

The Los Angeles Department of Water and Power and Los Angeles mayor Mayor Eric M. Garcetti are proposing a $3B project to utilize Hoover Dam for hydroelectical pumped power storage to manage electricity demand.

The concept targeted, for 2028, is to pump water uphill from 20 miles downriver from the dam using peak solar and wind power to be released for hydro-generation when required.  Significant political, environmental and economic challenges will need to be considered and addressed.

Sustainable Fishing (and Guiding), Catch and Release Best Practices

When I started fishing in 1960, we killed every fish we caught. Over a half-century later, even though there are 1000 times more anglers, there are more fish and larger trout in Colorado waters.  A big reason for this is the number of folks practicing Catch and Release or Catch and Choose the Fish to Release.

Over the years we have learned more about what stresses fish and techniques for proper fish handling.  Fish released properly have a 90% chance of survival

This link describes the best practices for handling fish to increase their chance of survival after release:

City of Boulder Hydroelectric Plants?

Who would have guessed?…  The city of Boulder is a hydroelectric power generator.  On May 21, 2018 the city signed a contract with Tri-State Generation and Transmission Association for the sale of hydroelectric power generated at the Boulder Canyon,  Orodell, Sunshine, Maxwell and Kohler hydroelectric plants. The estimated revenue of $500,000 a year will be used for water utility capital improvements and operating costs.

The City of Boulder owns and operates eight hydroelectric power plants, with one purchased and seven constructed since 1985.  These facilities were installed on existing water supply pipelines without any additional dams or overhead transmission lines.  Total generation for 2016 was 40,798,941 kilowatt hours (kWh)

Tri-State is the not-for-profit, cooperative power supplier to 43 electric distribution cooperatives and public power districts in Colorado, Nebraska, New Mexico and Wyoming.


Fish Kill due to Boulder Canyon Hazmat Spill on May 1st

On May 1, 2018 there was a hazardous material spill of 250 gallons of sodium hydroxide or caustic soda in upper Boulder Canyon near mile marker 28.5.  The materials were being delivered to the Nederland Water Treatment plant an one container fell off the truck onto the road shoulder.  Authorities were notified by 9:30am arrived at the scene at 10:51am.  By then all the materials had leaked from the container.  In the following days and week fishing guides observed multiple dead and dying fish and populations do not appear to have recovered to pre-spill levels.  The community response was limited and Boulder Waterkeeper believes that additional procedures are necessary to prevent and address future contamination events.

Supreme Court Allows Significant Watershed Restoration Decision to Stand

With a split decision announced on June 11, 2018 the U.S. Supreme court lets stand a ruling in the Washington v. United States ‘culvert’ case that has immediate impact for stream restorations in the State of Washington and potential long term implications for watershed protection in Colorado and the nation.  In commitments made by the U.S. in the 1850s in treaties with tribal nations salmon fishing rights were established and then reaffirmed in federal cases in the 1970s.  The affirmed ruling requires the State of Washington to repair salmon access and habitat that is degraded by 900+ road culverts.  The anticipated cost is in excess of $2.4B.  The implications for other watersheds, the Public Trust Doctrine and Rights of Nature arguments are still being evaluated.

Sugarloaf Water Contanimation

Boulder residents of the Sugarloaf neighborhood are being advised by the Sugarloaf Fire Protection District (SFPD) to not use their well water due to elevated levels of perfluorooctanaic acid (PFOA) and perfluorooctane sulphate (PFOS) that exceed federal safety standards.  These chemicals commonly known as PFCs have been linked to health effects ranging from birth defects to bladder and prostate cancers.  Samples taken by the fire district from their wells on April 1 and May 10 both have elevated levels.  Additional tests from the well of a nearby homeowner also show evidence of contamination.  On Tuesday evening June 19th at the SFPD Board Meeting representatives will provide a briefing for concerned residents.  More information is available at

Waterkeeper Alliance 2018 Conference


Boulder Waterkeeper participated in the international Waterkeeper Alliance 2018 Conference in Buffalo NY.  Participants from 29 countries and 35 states attended the event to share information and strategies to preserve and protect drinkable, drinkable, fishable and swimmable waters around the world.  The conference highlight was a rousing speech by Bobby Kennedy Jr. on the links between environmental and social justice and pithy political comments on the dark alchemies of demagoguery.   Specific sessions and discussions on dam removal, instream flow, the rights of nature and Aloha ʻĀina provided strategies and insights that will be used to focus and refine Boulder Waterkeeper strategies and actions.
