2014 Watershed Health Report Card Analysis
•
0 likes•374 views
The document provides an overview and results from the 2014 Watershed Health Report Card for Pierce County. It discusses two key metrics used to evaluate watershed health: 1) the rate of compliance with stormwater requirements, and 2) trends in watershed health as measured by water quality and benthic indices. Overall compliance rates have increased countywide since 2009. Some watersheds showed improvements in both indices while others showed declines or mixed results. Specific results are presented for several watersheds, including the Key Peninsula/Islands, Nisqually, and Chambers-Clover watersheds.
