Clamp study - updated feb. 2005

  1. 2. <ul><li>Capitol Lake is in trouble </li></ul><ul><li>Objective of Capitol Lake Committee 10-year Management Plan: “ Complete an estuary feasibility study to determine a long-range management decision” </li></ul><ul><li>Study to provide objective, scientific information for impartial decision on the long-term management of Capitol Lake </li></ul>Why is the study needed?
  2. 3. <ul><li>We need this information to make a decision about the basin’s future. </li></ul><ul><li>We have more than 50 years of data on a lake environment, but virtually no information on how an estuary might function within the Capitol Lake basin. </li></ul><ul><li>The Estuary Feasibility Study is designed to fill this data gap. </li></ul><ul><li>NOTE : Undertaking the study does not mean a decision has been made about the future of the basin. </li></ul>Why the study is needed?
  3. 4. What are the options for Capitol Lake? <ul><li>Fresh Water Lake – This option will require extensive dredging of the middle basin now and the middle and north basins every year into the future. Last dredging was in 1986. </li></ul><ul><li>Fresh Water Marsh – This option is the “Do Nothing” alternative. Capitol Lake will continue to fill with sediment creating shallow wetland habitat. </li></ul><ul><li>Tidal Estuary – This option is what will be evaluated under this study. Is it feasible to restore an estuary within a highly developed urban community? </li></ul><ul><li>Combined Lake/Estuary – This option may result from alternative estuary designs with an area for fresh water created within the basin. </li></ul>
  4. 5. <ul><li>Sediment is filling in Capitol Lake </li></ul><ul><li>Poor habitat and water quality </li></ul><ul><li>Noxious weeds infest the lake and shoreline </li></ul>What are the problems with the lake?
  5. 6. <ul><li>Deschutes River dumps 20,000 to 57,000 cubic yards of sediment into the lake each year </li></ul><ul><li>Lake volume has decreased 26% since 1951 </li></ul><ul><li>Capitol Lake is turning into a freshwater marsh </li></ul>How much sediment is there? Courtesy The Olympian
  6. 7. What is wrong with the lake’s water quality? <ul><li>High levels of phosphorus, which can increase algae blooms </li></ul><ul><li>Contamination from more than 80 stormwater outfalls </li></ul><ul><li>High water temperatures in summer that harm fish and wildlife </li></ul><ul><li>A warm, shallow lake is a perfect place for noxious weeds to grow, such as Eurasian watermilfoil </li></ul>
  7. 8. What are the goals of the feasibility study? <ul><li>Increase our understanding of the estuary alternative - to a level equal to that for the management of Capitol Lake. </li></ul><ul><li>Determine if it is possible to create a viable, self-sustaining estuary - given all the existing physical constraints and the urban setting. </li></ul><ul><li>Create an objective analysis of the costs and benefits of the estuary alternative - in terms of social and environmental issues. </li></ul><ul><li>Provide the completed study to the CLAMP Steering Committee. </li></ul>
  8. 9. What will be studied? <ul><li>Hydraulic and Sediment Transport Analysis: Determine where sediment would go if an estuary was restored. What would be impacts of sediment moving from the lake into Budd Inlet? </li></ul><ul><li>Capitol Lake Bathymetry Study: Survey the bottom of the lake. </li></ul><ul><li>Reference Estuary Study: Examine other Puget sound estuaries to determine how they function. </li></ul><ul><li>Biological Considerations: What type of habitat will form, and how long will it take? </li></ul>
  9. 10. What will be studied? (continue) <ul><li>Design Alternatives: Use studied data to develop feasible design alternatives. A large portion of the original estuary has been filled. It is not as simple as removing the dam. </li></ul><ul><li>Net Benefit Analysis: Compare the benefits and costs of restoring the estuary, dredging the lake, or doing nothing. Consider the community values and infrastructure replacement costs and impacts. </li></ul><ul><li>Independent Technical Review: The final data, reports, and recommendations will receive scientific peer review. </li></ul>
  10. 11. How much will the study cost? <ul><li>Working estimate: $900,000 </li></ul>How much money is available now? General Administration $232,500 Ecology $32,000 State Fish & Wildlife $22,000 City of Olympia $20,000 Port of Olympia $10,000 Puget Sound Action Team $30,000 Salmon Recovery Funding Board $222,000 TOTAL: $568,500 Cash & in-kind support $900,000 $0 $568,500
  11. 12. What are other possible funding sources? <ul><li>U.S. Fish and Wildlife Service (USFWS) </li></ul><ul><li>National Oceanic and Atmospheric Administration (NOAA) </li></ul><ul><li>Environmental Protection Agency (EPA) </li></ul><ul><li>LEGISLATURE </li></ul>
  12. 13. How much is the Legislative budget request? <ul><li>$222,000 Multi-Agency Budget request submitted by the Department of Fish and Wildlife </li></ul><ul><li>This money ($222,000) will fund the design alternatives and the net benefit analysis. </li></ul>Courtesy The Olympian
  13. 14. What is being done now? <ul><li>Implement initial study tasks as funding becomes available </li></ul><ul><li>Seek additional opportunities to fully fund the study through grants, appropriations, and local resources </li></ul><ul><li>Support Ecology’s water cleanup study of Capitol Lake and Budd Inlet </li></ul>USGS staff conducting the bathymetric survey
