Keyhole Reservoir Investigated for Cyanobacterial Blooms

unnamed

August 10, 2020

A concerned visitor alerted Wyoming State Parks that their pets became ill after a recent visit to Keyhole State Park.  

KHHCBsOut of an abundance of caution, park staff posted warning signs and contacted the Wyoming Department of Environmental Quality (DEQ).  That agency is proceeding with an investigation of a potential harmful cyanobacterial bloom (HCB). 

The investigation is currently only for the section of the reservoir in the upper end of Cottonwood Bay, potentially affecting Pronghorn, Tatanka, Arch Rock, Cottonwood, and Homestead campgrounds.  

Recent and repeated satellite imagery does not show the presence of HCB, and park staff have visually surveyed the potentially affected areas on land and from the reservoir, and have not seen any evidence of a bloom. DEQ is sending staff to investigate, and the Wyoming Department of Health has been alerted.

Lakes or reservoirs under investigation are not closed. Marinas, lakeside parks and camping facilities are open for business. Any closed areas will be specifically noted. Visitors are advised to err on the side of caution and use their best judgement when recreating in this area.

BB-great-dam-day-8-2011hBuffalo Bill Dam Visitor Center along with Buffalo Bill State Park host this year’s event at the Visitor Center located six miles west of Cody on HWY 14/16/20.

In addition to the events planned, there will be different interpretive learning stations located below the visitor center on the old road to Yellowstone below the dam.

Through cooperation with the Bureau of Reclamation, the old dam road is open  next to the visitor center one time during the year, allowing the public to walk or ride bicycle to take in the views from 9 a.m. until 3 p.m. Rides back to the center will be available. 

Fat Racks BBQ will have food available for purchase at the visitor center lot. Also, the Bureau of Land Management will have activities for kids to participate in.

Buffalo Bill Dam was completed in 1910 and is on the National Register of Historic Places. Buffalo Bill Dam was the tallest dam in the world upon completion. Construction began in 1904 and work was dangerous, difficult and tedious.

The completed water storage supplies four irrigation districts encompassing over 93,000 acres of farmland.

Youth and adults alike will find the views and history fascinating. Staff and volunteers will be on-site to answer questions and provide assistance.

The event is open and free to the public. For any questions, please contact the Buffalo Bill Dam Visitor Center General Manager Leslie Slater Wilson, at (307) 527-6076.

Boysen Reservoir: Harmful Cyanobacterial Bloom (HCB) Recreational Use Advisory

unnamed

August 7, 2020

 

The Wyoming Department of Health has issued recreational use advisories for Boysen Reservoir, Ocean Lake, Saratoga Lake, Wheatland Reservoir #3, and Leazenby Lake due to harmful cyanobacterial blooms (HCB). HCBs are also referred to as harmful algal blooms (HABs) since cyanobacteria are commonly known as blue-green algae. The Department of Health issues advisories to inform the public that there may be health risks for people and animals in areas where HCBs occur. Lakes and reservoirs under a recreational use advisory are not closed since HCBs may only be present in certain areas of the waterbody and conditions can change frequently. The advisory will remain in place until the bloom has fully dissipated and cyanotoxin concentrations are below recreational use thresholds identified in Wyoming's HCB Action Plan, or until the primary recreation season ends on September 30th, whichever comes first.

Potential blooms were identified by satellite imagery from the Cyanobacteria Assessment Network (CyAN) or reported to the Wyoming Department of Environmental Quality. The Wyoming Department of Environmental Quality visited the lakes and reservoirs on July 29, 2020 and collected water samples. Cyanobacteria densities exceeded the 20,000 cells/mL recreational use threshold identified in Wyoming’s HCB Action Plan. Cyanotoxin results are pending. The Wyoming Department of Health is working directly with resource management agencies to ensure that signs are posted at the lakes and reservoirs. The status of advisories in Wyoming as well as other HCB resources can be found at WyoHCBs.org.

If you encounter a potential HCB, the Wyoming Department of Health and Wyoming Livestock Board recommend the following:

  • Avoid contact with water in the vicinity of the bloom, especially in areas where cyanobacteria are dense and form scums.
  • Do not ingest water from the bloom. Boiling, filtration and/or other treatments will not remove toxins.
  • Rinse fish with clean water and eat only the fillet portion.
  • Avoid water spray from the bloom.
  • Do not allow pets or livestock to drink water near the bloom, eat bloom material, or lick fur after contact.
  • If people, pets, or livestock come into contact with a bloom, rinse off with clean water as soon as possible and contact a doctor or veterinarian.

Seminoe Reservoir: Harmful Cyanobacterial Bloom (HCB) Recreational Use Advisory

unnamed

August 7, 2020

 

The Wyoming Department of Health has issued a recreational use advisory for Seminoe Reservoir in Carbon County due to a harmful cyanobacterial bloom (HCB). HCBs are also referred to as harmful algal blooms (HABs) since cyanobacteria are commonly known as blue-green algae. The Department of Health issues advisories to inform the public that there may be health risks for people and animals in areas where HCBs occur. Lakes and reservoirs under a recreational use advisory are not closed since HCBs may only be present in certain areas of the waterbody and conditions can change frequently. The advisory will remain in place until the bloom has fully dissipated and cyanotoxin concentrations are below threshold values, or until the primary recreation season ends on September 30th, whichever comes first.

On July 9, 2020, satellite imagery from the Cyanobacteria Assessment Network (CyAN) identified elevated densities of cyanobacteria covering a large portion of Seminoe Reservoir. The Wyoming Department of Environmental Quality visited the reservoir on July 15, 2020, and collected water samples at the Boat Club Picnic Area. Cyanobacteria densities exceeded the 20,000 cells/mL recreational use threshold identified in Wyoming’s HCB Action Plan. Cyanotoxin results are pending. The status of advisories in Wyoming as well as other HCB resources can be found at WyoHCBs.org.

The Wyoming Department of Health is working directly with Seminoe State Park to post advisory signs at the reservoir.

The Wyoming Department of Health and Wyoming Livestock Board recommend the following:

  • Avoid contact with water in the vicinity of the bloom, especially in areas where cyanobacteria are dense and form scums.
  • Do not ingest water from the bloom. Boiling, filtration and/or other treatments will not remove toxins.
  • Rinse fish with clean water and eat only the fillet portion.
  • Avoid water spray from the bloom.
  • Do not allow pets or livestock to drink water near the bloom, eat bloom material, or lick fur after contact.

Wyoming Outdoor Recreation to Benefit from Recently Signed Great American Outdoor Act Legislation

unnamed

 August 4, 2020

Bolstered by bipartisan Congressional support, the Great American Outdoors Act (GAOA), recently signed into law by President Donald Trump, provides full and permanent funding of the Land and Water Conservation Fund.

           This legislation ensures that Wyoming and the rest of the nation will benefit from this critical funding for land and water conservation projects, recreational construction and historic preservation.

           GLGlendo-Fish-Cleaning-Station Although funding has been inconsistent over the years, public lands and local recreation has benefitted throughout the nation. This new legislation ensures funds are set aside for conservation and recreation and will not be redirected for other purposes.

            The Land and Water Conservation Fund is America’s most important conservation program. It is funded from the federal oil and gas leases on the Outer Continental Shelf pursuant to the Gulf of Mexico Energy Security Act and appropriated by Congress.

            Administered by the Wyoming State Parks & Cultural Resources agency’s Division of State Parks, Historic Sites and Trails, this year’s LWCF funding for the Cowboy State totaled $1,843,483. Since its inception, the program has funded hundreds of recreational projects throughout Wyoming totaling nearly $40 million.

            Some examples from last year’s funding included a grant to the Town of Marbleton to building a community fishing pond, the City of Sundance to build a central park and the City of Cheyenne to replace synthetic turf on a baseball field.

Kathy Lenz of the City of Sundance Treasurer’s Office is excited for this project in her community. 

"The Land and Water Conservation Fund grants are an invaluable asset to us,” Lenz said. “These grants make it possible for us to fund recreational facilities that we normally wouldn't be able to."

“We encourage communities to apply and to call with any project planning or grant application questions,” Wyoming State Parks Grant Manager Louisa Lopez said. “There is still time to put some planning and thought into your projects as these applications will be due at the end of the year.”

To be eligible, the project site must be maintained for public outdoor recreation for perpetuity, and the applicant must be a municipality, county, school district or recreation district. LWCF grant applications must be postmarked no later than December 31.

For more information contact Louisa Lopez, Grant Manager, SPCR 307-777-6491 or This email address is being protected from spambots. You need JavaScript enabled to view it..

sinksThe Sinks Canyon State Park Master Plan is a 20-year plan for the park, directing future improvements and guiding continued management of the park as a major recreational asset for Wyoming. The process was structured in four phases over the past year, which involved collecting information, feedback, and ideas about ways to both enhance the visitor experience at the park and preserve its resources for future generations to enjoy. 

This public comment period will be the last opportunity for the public to weigh in on this plan before it is approved and put into action. While the meeting has shifted online, there are still opportunities for the public to make their voices heard regarding the future of the park.

For more information and to stay up to date with the project, please visit the plan's website, or call the State Parks Planning Section at 307-777-6968.
