Synthesis of Biological Research On
DRAFT FINAL November 2007 Review of Biological Research on Juvenile and Adult Salmonid use of Vancouver Lake Prepared by: Portland District U.S. Army Corps of Engineers Environmental Resources Review of Biological Research on Juvenile and Adult Salmonids and Survival at Vancouver Lake Abstract This document provides a synthesis of known biological research on juvenile and adult salmonids at Vancouver Lake, Vancouver Washington. This review of literature was prepared to support the Portland District U.S. Army Corps of Engineers involvement with the Vancouver Lake Watershed Partnership under the Corps Section 536 program. This specialized Corps program authority promotes the improvement of tidally influenced off-channel habitat in the Lower Columbia River. The goal of this report is to provide the Corps of Engineers the best information available to make management decisions on whether or not to move forward with improving habitat for salmonids at Vancouver Lake. Background and Lake History Vancouver Lake (approximately 2,600 acres) provides a variety of functions to the surrounding community including wildlife habitat, flood control, boating, bird watching, hiking, hunting and other recreational activities as well as environmental education and stewardship opportunities. The Lower Columbia River has been impacted over the past 100 years by the implementation of navigation features associated with the Columbia and Lower Willamette Rivers Navigation Channel, urban and rural development, federally funded flood control projects, and flow fluctuations attributable to the Federal Columbia River Power System. The cumulative effect of these actions has contributed to the degradation of the quality and quantity of the off-channel habitat in the Columbia River Basin. -

Davis Bar and the I-5 area should continue to produce some catches of spring chinook. Gillnets will take the week off as test netting yielded more wild steelhead than spring chinook. These quality steelhead are likely destined for the Sandy and Clackamas systems. Willamette flow continued to moderate through the end of February as winter steelhead counts tapered off. -

Beyond Eutrophication: Vancouver Lake, WA, USA As a Model System for Assessing Multiple, Interacting Biotic and Abiotic Drivers of Harmful Cyanobacterial Blooms

Bollens 1,2 1 School of the Environment, Washington State University, Vancouver, WA, 98686, USA; [email protected] (T.L.); [email protected] (V.R.); [email protected] (S.M.B.) 2 School of Biological Sciences, Washington State University, Vancouver, WA 98686, USA * Correspondence: [email protected]; Tel.: +1-360-546-9115 Received: 16 April 2018; Accepted: 8 June 2018; Published: 10 June 2018 Abstract: Eutrophication of lakes and reservoirs has contributed to an increase in the magnitude and frequency of harmful cyanobacterial blooms; however, the interactive effects of nutrient availability (eutrophication) and other abiotic and biotic drivers have rarely been comprehensively studied in the field. We undertook an eight-year (2005–2013) research program that assessed the interaction of multiple factors driving cyanobacterial blooms in Vancouver Lake, a large, shallow eutrophic lake in Washington, USA. Our program consisted of nearly continuous monthly or weekly monitoring of water quality and plankton community composition over eight years, as well as multiple zooplankton grazing experiments over three years. We found a relatively consistent seasonal succession of phytoplankton and zooplankton assemblages, and a pattern of interacting factors influencing cyanobacterial bloom dynamics. Typically, a combined effect of decreased dissolved inorganic nitrogen (N), a sudden increase of dissolved inorganic phosphorus (P), and a cascading effect of zooplankton grazing created a ‘perfect storm’ of conditions that promoted the rapid proliferation of cyanobacteria over the two to three weeks before a bloom. -

Explore Your Watershed Answer
Welcome teachers! This work booklet is based on the Stormwater Partners new online tool, ‘Explore Your Watershed’, an ArcGIS StoryMap. This StoryMap was created by Eric Lambert of Clark County Public Works with a grant from the Lower Columbia Fish Recovery Board to be an immersive learning experience based on information about the ten major watersheds in Clark County. These asynchronous, self-paced worksheets can be added to your Google classroom, or printed in packets for physical distribution, and can be used in lieu of the Student Watershed Monitoring Network’s in class introductory presentation to prepare students to understand how watersheds function while setting the stage for collecting and interpreting their monitoring site’s water quality data. These worksheets can be done in the order and/or subject matter you choose. To explore this StoryMap, follow this link: https://arcg.is/iGXrq If you have any questions, contact Eric Lambert at [email protected] or Rainy Rau at [email protected] Chapter 1 – Clark County Watersheds! 1. What is a watershed? Hint: Watch the video in the ‘What is a watershed?’ section. a. An area of land that drains to a common stream, river or lake. b. A shed that holds water. c. A place in the forest where water comes from. 2. How many miles of streams are in Clark County? Hint: Look in the ‘Our streams’ section. a. 1,000 miles b. 2,000 miles c. More than 2,400 miles 3. What is the largest watershed that is entirely in Clark County? Hint: Watersheds along the border of Clark County also encompass other counties. -

Monitoring Report Lacamas Lake Annual Data Summary for 2007
Monitoring Report Lacamas Lake Annual Data Summary for 2007 Background Since the original settlement of Clark County, land use changes have dramatically altered Lacamas Lake and resulted in conditions that reduce the lake’s suitability for fishing, swimming, and aesthetic enjoyment. High nutrient inputs (primarily phosphorus but also nitrogen) from the watershed have been identified as a major contributing factor. Ongoing problems include summertime dissolved oxygen depletion, poor water clarity, high levels of algae growth, nuisance blue-green algae blooms, and dense beds of aquatic plants. Grant-funded activities implemented by Clark County and other agencies between 1987 and 2001 reduced agricultural phosphorus sources and increased public awareness of lake issues. Water quality monitoring indicated that phosphorus concentrations in the lake and its major tributary, Lacamas Creek, were substantially reduced during this period. Despite these improvements, however, water quality problems persist in Lacamas Lake. Since the conclusion of grant-funded work in 2001, Clark County’s Clean Water Program has continued routine monitoring of this resource to provide information for future lake management decisions. This report summarizes monitoring activities and data collected from May through October 2007. Historical lake data and nutrient loading were most recently summarized following data collection in 2003. The April 2004 report Lacamas Lake Nutrient Loading and In-Lake Conditions may be viewed at http://www.clark.wa.gov/water-resources/documents.html. Summaries of grant-funded activities from 1987 through 1998 are also available. Lake Description Location Lacamas Lake and Round Lake are located in Clark County, Washington, on the northern boundary of the city of Camas. -
