2014 Aquatic Weed Surveys In Timothy Lake, Lake Harriet, North Fork Reservoir, Faraday Lake, And Estacada Lake, Rich Miller, Mark D. Sytsma, Jeffrey Thomas Brittain
Center for Lakes and Reservoirs Publications and Presentations
The Clackamas River Hydroelectric Project No. 2195 (Project) is located on the Oak Grove Fork of the Clackamas River and the mainstem of the Clackamas River in Clackamas County, Oregon. Reservoirs included in the Project include Timothy Lake, Lake Harriet, North Fork Reservoir, Faraday Lake, and Estacada Lake. The operator of the Project, Portland General Electric (PGE), was issued a license on December 21, 2010 by the Federal Energy Regulatory Commission (FERC) for continued operations and maintenance. The Final Environmental Impact Statement (FEIS) for the license noted that regular surveys for invasive aquatic weed species would be conducted as part …
Physical, Chemical And Biological Assessment Of Yoncalla Log Ponds, Rich Miller, Mark D. Sytsma, Angela L. Strecker
Physical, Chemical And Biological Assessment Of Yoncalla Log Ponds, Rich Miller, Mark D. Sytsma, Angela L. Strecker
Center for Lakes and Reservoirs Publications and Presentations
The Yoncalla Log Ponds are a series of four ponds located in within the city limits of the town in Yoncalla in northern Douglas County, Oregon. The ponds were created in stages between the late 1930s and the 1950s and used for log storage through the 1970s (North Douglas Betterment 2014). North Douglas Betterment purchased the land surrounding the ponds and contracted with the Center for Lakes and Reservoirs at Portland State University to assess the current morphometry, vegetation and water quality status of the ponds and provide recommendations for management of the aquatic vegetation. The scope of this document …
Osmb Final Report, Task 7: Online Atlas Of Oregon Lakes - Aquatic Invasive Species Interface, Rich Miller, Mark D. Sytsma
Osmb Final Report, Task 7: Online Atlas Of Oregon Lakes - Aquatic Invasive Species Interface, Rich Miller, Mark D. Sytsma
Center for Lakes and Reservoirs Publications and Presentations
In order to educate a broad cross section of the public about Aquatic Invasive Species (AIS) distributions and survey efforts in Oregon’s lakes and reservoirs, database connections were created to display AIS information on the Online Atlas of Oregon Lakes (aol.research.pdx.edu/). The connections allowed for the dynamic display of AIS survey records stored in three separate databases: the Center for Lakes and Reservoir’s Oregon Aquatic Plant and Mussel Databases and the iMapInvasives database. AIS survey records collected by the Center for Lakes and Reservoirs were also reported to the iMapInvasives database.
Osmb Final Report, Task 4: Oregon Lake Watch, Angela L. Strecker, Rich Miller, Vanessa Morgan
Osmb Final Report, Task 4: Oregon Lake Watch, Angela L. Strecker, Rich Miller, Vanessa Morgan
Center for Lakes and Reservoirs Publications and Presentations
The Oregon Lake Watch (OLW) volunteer monitoring program was resurrected after over a decade in hibernation. The new program was designed to educate the public about threats of aquatic invasive species (AIS), provide early detection of AIS invasions, and provide long term water quality data for the better management of Oregon’s lakes and reservoirs. Protocols were created for citizen scientists to survey for AIS, collect temperature and water clarity data, and record the data through an online data entry portal. An OLW website was developed to educate about AIS and provide survey protocols and identification materials to volunteers. AIS surveys …
Osmb Final Report: Task 5. Zebra And Quagga Mussel Early-Detection Monitoring In High Risk Oregon Waters, Steve W. Wells, Mark Sytsma
Osmb Final Report: Task 5. Zebra And Quagga Mussel Early-Detection Monitoring In High Risk Oregon Waters, Steve W. Wells, Mark Sytsma
Center for Lakes and Reservoirs Publications and Presentations
Neither zebra nor quagga mussels (Dreissena polymorpha and D. rostriformis bugensis, respectively) were detected by Portland State University (PSU) during their early detection sampling in Oregon water bodies during 2013. PSU conducted sampling for planktonic larvae, juvenile, and adult mussels at nine Oregon water bodies during the July to August period coinciding with water temperatures favorable for mussel spawning. A total of 113 plankton samples were collected and over 1.6 million liters of lake water were filtered through 63-μm mesh nets during plankton sample collection. The greatest sampling effort occurred in East Lake, Prineville Reservoir, and Paulina Lake; these water …
Aquatic Invasive Species Surveys Of Eastern Oregon Waterbodies In 2013 And 2014, Rich Miller, Mark D. Sytsma
Aquatic Invasive Species Surveys Of Eastern Oregon Waterbodies In 2013 And 2014, Rich Miller, Mark D. Sytsma
Center for Lakes and Reservoirs Publications and Presentations
Early detection aquatic invasive species (AIS) surveys were conducted at 33 Eastern Oregon waterbodies during the summers of 2013 and 2014. Submerged aquatic plants, gastropods, bivalves, and crayfish were collected using a thatch rake, benthic dredge, plankton net, and modified minnow traps. Shoreline aquatic noxious weeds were noted when present and water quality characteristics were measured. Two AIS snail species, one AIS crayfish species, and five AIS plant species were detected during the surveys. Big-ear radix snails (Radix auricularia) were newly detected at 14 waterbodies distributed across the survey area. Chinese mystery snails (Cipangopaludina chinensis) were …

Osmb Final Report: Task 3. Containment Strategies For Eurasian Watermilfoil Infested Central Or Lakes, Vanessa Morgan, Mark Sytsma
Center for Lakes and Reservoirs Publications and Presentations
In recent years, public awareness of aquatic invasive species (AIS) has increased considerably in Oregon and elsewhere in the western U.S.. News articles, boat inspection stations and AIS permit programs have drawn attention to the threat of aquatic invasive species, especially animals like zebra mussels (Dreissena polymorpha), quagga mussels (Dreissena bugensis), and New Zealand mudsnails (Potamopyrgus antipodarum). However, invasive aquatic plants are also capable of causing severe impacts and may similarly be transferred between waterbodies on boats, trailers or other equipment. Heavy infestations can hinder recreational use by motorized and non-motorized boats, snag fishing lines, threaten the safety of swimmers …

Osmb Final Report: Task 6. Tenmile Lake Boat Wash Effectiveness Monitoring, Samuel Cimino, Angela L. Strecker
Center for Lakes and Reservoirs Publications and Presentations
Public awareness of aquatic invasive species and proper boat cleaning procedures may prove to be beneficial in reducing the transport and establishment of aquatic invasive species like New Zealand mud snails and zebra and quagga mussels as well as hydrilla and Eurasian watermilfoil. The primary objectives of this research project were to observe the use and determine the efficacy of a public boat wash station as well as increase the public’s awareness of proper boat cleaning procedures and aquatic invasive species. The Tenmile Lakes Basin Partnership, Oregon State Marine Board, and the United States Forest Service (USFS) have undertaken an …
