Newman Lake Watershed Plan

In 1989, the Newman Lake Flood Control Zone District received a Referendum 39 Grant from the Washington State Department of Ecology to perform the Newman Lake Restoration Project Phase II. This watershed plan is one element of the Phase II project. The Department of Ecology grant funds 75% of the original $860,076 project, and local Flood Control Zone District assessments fund the remaining 25%. (The total project costs were revised later to include additional expenses associated with the aeration system.)

The information and recommendations in this plan were generated by the Newman Lake Watershed Plan Committee, a group of Newman Lake area residents and governmental agency representatives. Staff from the Spokane County Engineer's Office, as administrator of the Flood Control Zone District, provided the necessary coordination and support for the documentation.

The objective of this watershed plan is to evaluate water quality problems associated with watershed activities and to formulate means of correcting the problems. The goal is to reduce the nutrient loading to Newman Lake. To view or download of the Newman Lake Watershed Plan in Adobe PDF format, please link to the Newman Lake Watershed Plan
