Howard Miller Steelhead Park (HMSP) is a County Park that is managed by the Skagit County Parks Department. The park is located in the Middle Skagit River Floodplain near the confluence of the Sauk River. The Upper Skagit River upstream of the confluence with the Sauk contains the highest density of spawning areas for the threatened Chinook salmon in the entire Skagit watershed. The off-channel sloughs and wetlands associated with the floodplain in the middle and upper Skagit River provide critical rearing habitat for juvenile Chinook and coho salmon originating in the Upper Skagit, Sauk and Middle Skagit River.

Skagit Fisheries Enhancement Group (SFEG) has been working with Skagit County Parks and the U.S. Fish and Wildlife Service (USFWS) at the HMSP site since 2006, restoring riparian habitat. Riparian restoration has been conducted in two phases. Invasive species control and planting native trees and shrubs in 2007 and 2008 focused on the area along the Skagit River. In 2009 the planting areas were expanded to include the west side of the existing tributary, and an area adjacent to the existing forest on the west side of the park. Planting days included working with school groups and volunteers. Riparian vegetation planted to date has included conifers and deciduous species such as willows and cottonwoods that will withstand the effects of periodic flooding. Overlook gaps were left in the vegetation to allow for public observation of salmon and salmon habitat. Howard Miller is a pesticide-free park, and thus creative maintenance activities including mulching and installation of cardboard have been required for invasive plant control. Invasive plant control focused on blackberry, reed canary grass and Scotch broom removal. Prior to restoration the undeveloped portion of the Howard Miller Steelhead Park lacked woody riparian vegetation and had been heavily colonized by invasive species such as Scotch Broom, Himalayan blackberry and reed canary grass. Lack of bank stabilizing vegetation has resulted in erosion and excessive sediment to the salmon bearing waters of the Wild and Scenic Skagit River. This project aims to restore native riparian vegetation along 2,440 feet of the Skagit River at the Howard Miller Steelhead Park.

In 2010 SFEG proposed relocation of a small tributary stream that currently crosses the park into a former Skagit River channel on the north side of the park that flows parallel to the base of the old railroad grade. More information on this project can be found in Habitat Work Schedule as the Howard Miller Off Channel Enhancement Project.
