Introduction to Hybrid Waterfront Management Plan

Get engaged in the development of the State ⁄ DES produced Environmental Impact Statement (EIS) to select a new long-term Community Plan for our Deschutes Urban Watershed and Capitol Lake. Read the CLIPA Document- July 2018

Hybrid/Split Lake with Restored Estuary and Waterfront Plan

This plan provides specific benefits and advantages to the Community and Environment when compared to other alternatives being considered. Through compromise and creativity, it provides a remarkable system which balances the values and needs of our environment and the vast majority in our community. Read the CLIPA Document- July 2018

Review of Supplemental Modeling Scenario Report

The Washington Department of Ecology’s Report, “Supplementary Modeling Scenarios” purports to demonstrate that Capitol Lake has a negative effect on Puget Sound. That Report presents outputs of a complex computer simulation, the “Budd Inlet Model,” that are said to support the authors’ claims. That is not the case. In fact data in that report supports the view that Capitol Lake’s effects on Puget Sound are actually beneficial. Summary, Outline, and Chapter or Full Report PDFs Dr. David H. Milne, PhD - July 2018

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

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 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

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

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 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

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.
