The Watershed Health Monitoring (WHM) program visits probabilistic (randomly-selected) sites and other hand-selected sites across Washington. We sample about 50 random sites within each of 7 Status and Trends Regions (STRs) during each round of sampling. Data in this file represent information collected during Round 1 probabulity sampling in the Upper Columbia STR (summer 2012) along with some other events from the region. Reported here are just a select few of the metrics. The full suite of habitat data is available from our web site: http://tinyurl.com/WatershedHealth. Macroinvertebrate community scores reported here are from this source: http://pugetsoundstreambenthos.org.
This is a list of wood volume measurements among randomly selected stream sites in Washington State during 2009-2016. Data were collected for the Department of Ecology's Watershed Health Monitoring surveys. This list only displays data from the most recent sampling event at any site.
This file lists random sites sampled by the Department of Ecology's Watershed Health Monitoring program during 2009-2016. The list is limited to those sites known to be occupied by salmon or trout at some time during the year. It also shows percentage of the stream network represented by the site and whether the observed sediment on the surface of the stream bottom exceeded levels estimated to be optimum for sediment-sensitive salmonids.
This dataset lists random sites sampled by Watershed Health Monitoring surveys during 2009 to 2016. It provides adjusted spatial weights (km of stream represented by the site). It also provides metric values for proximity-weighted presence of riparian disturbance from any type (PWP all) and the disturbance condition rating (low, medium, or high). Sites are assigned regional and survey year membership.
This is a list of random sites sampled by the Department of Ecology's Watershed Health Monitoring Program during 2009-2016. It includes data for riparian cover as measured with a densiometer at the bankfull margins and the amount of stream network represented by the random site. Densiometer data are assigned ratings of riparian condition relative to reference conditions.
Large woody data (as volume per area) from Watershed Health Monitoring surveys conducted by the Department of Ecology during 2009-2019. Data from Recovery Regions is intended for the 2020 State of the Salmon Report. In the Watershed Health database, refer to the metric called "LWDVolumeMSq".
Average percent of "pebble count" stations that are of sand or smaller size. Data are from Watershed Health Monitoring surveys conducted by the Department of Ecology during 2009-2019. Data from Recovery Regions are intended for the 2020 State of the Salmon Report. Reference the metric "PCT_SandFines" in the Watershed Health database. The reference category is based on Table 2 of Bryce et al (2010) J. N. Am. Benthol. Soc., 2010, 29(2):657–672 plus 5.5% for adjustment to bankfull channel rather than wetted.
Riparian canopy data, as measured with convex densiometer. These are from Watershed Health Monitoring surveys conducted by the Department of Ecology during 2009 through 2019. Data from Recovery Regions are intended for the 2020 State if the Salmon Report. Reference this metric in the Watershed Health database: "X DensioBank".
