Reflecting Lake or Estuary? There is no easy, cost-free solution. read article

Science & Ecology

The managed lake option is the best alternative for managing the Deschutes River’s annual sediment load. This insures the continued viability of water dependent and public uses of the Olympia Harbor. read article

The Nature of Capitol Lake

Olympia began a Faustian bargain when it filled part of the Sound to create land for development. These uses have become a fixed part of life in this community. Capitol Lake has become part of this picture. read report

15 Reasons Why Capitol Lake is Better Than An Estuary

There is not even one scientifically demonstrable way in which the headwaters of an estuary improve the environment of Puget Sound and specifically the Budd Inlet estuary more than does Capitol Lake. Read the article

Capitol Lake: The Healthiest Lake in Thurston County

Capitol Lake is an environmental treasure that is worthy of preservation for many reasons, and sustainable by well known routine management procedures for all of the foreseeable future. The Lake has changed in ways that require understanding and action after a long period of neglect.summary & report

Capitol Lake: Protector of Water Qualty in Budd Inlet

A review of the Wa. State Dept. of Ecology document "TMDL Tech Report (2012)". The conclusion of this review is that Capitol Lake is the Deschutes River Watershed's biggest and best asset for preventing and reducing water quality degradation in Budd Inlet. summary & report

The Construction and Maintenance Cost of Turning Capitol Lake into Tidal Mud Flats

CLAMPs contention that removal of the dam is less costly than maintaining the lake is severely flawed. Not only are the ten year costs of dam removal far higher than maintaining the lake ($157 million versus $23.5 million) the long term costs of maintaining and improving the lake are also far less. read report

A Review Of Economic Impacts Associated With Capitol Lake

Converting the Lake into tidal mudflats would contribute nothing to the economy and would seriously degrade current economic benefits along with the loss of intangibles such as aesthetics and public pride. read report

Review of Estuary Infrastructure Costs

The concept for realigning Deschutes Parkway and reconstructing 5th Avenue represents a significant reduction in the usefulness, aesthetic quality, and safety of the overall facility. I believe that the design suggested by CLAMP for the tidal basin alternatives would not ultimately be acceptable to the community . . . read report

Impact on Fisheries & the Environment

I do not believe that turning the lake into a mud flat will enhance or improve the existing salmon and trout populations of the watershed. The restricted flow of water into the area above 4th avenue will not provide the typical flushing that would occur in an undisturbed estuary. read letter

Review of the "Capitol Lake Alternatives Analysis- Final Report"

Address is what is happening in the Deschutes River watershed that results from silt and sediment, along with toxic chemicals from storm water run off. If the proper steps are taken to control storm water runoff, the managed lake alternative will result in less sediment reaching the marinas and Budd Inlet. read report

The CLIPA White Paper

A realistic, practical & science based plan to improve water quality & sediment management in the Deschutes Watershed. Improving Capitol Lake requires a watershed-wide sustainable solution that is in line with the original lake vision as well as current and future needs. go to document
