West Broadway River Corridor Project
UPDATE: Draft West Broadway River Corridor Master Plan is ready for public review:
Following several years of public engagement, feasibility investigations and design work, Missoula Parks and Recreation and our project partners are excited to share a draft West Broadway River Corridor Master Plan. This ambitious project includes significant changes to riverfront parklands, trail systems and the Clark Fork River itself. This is a unique opportunity to provide comment on a project that will redefine how people and wildlife interact with the Clark Fork River in downtown Missoula.
The survey to give public feedback on the draft West Broadway River Corridor Master Plan is available here! Public comment period is through December 14, 2025. Please review the draft West Broadway River Corridor Master Plan Report for more detail on the design concept.
If you would like to provide feedback on design concept above please follow this link to the survey and for a more detailed report is available here: draft West Broadway River Corridor Master Plan.
The draft West Broadway River Corridor Master Plan outlines a new vision for the West Broadway River corridor. This report also captures the decision-making process and explains various aspects of the project area including plan approach, site assessments, infrastructure analyses, management challenges, key assets, preferred design concepts, alternative design concepts, feasibility and construction considerations, environmental permitting, and estimated project costs and timeline.
A thorough master planning process was critical to ensure this project aligns with community goals and to be competitive for future funding opportunities. Development of this Master Plan was made possible by the Missoula Redevelopment Agency Board’s allocation of tax increment financing (TIF) funds from Urban Renewal District II for professional design and engineering services. Project development and oversight is being coordinated by Missoula Parks and Recreation’s Ecosystem Services Division. Trout Unlimited is serving as the project manager with oversight from a steering committee with representatives from Missoula’s Parks & Recreation, Redevelopment Agency and Public Works & Mobility departments, and Montana Fish Wildlife & Parks. A consultant team including SWCA Environmental Consultants (formerly River Design Group), Morrison-Maierle Engineering, Field Studio Landscape Architects, and Recreation Engineering & Planning were contracted to develop the Master plan.
The draft West Broadway River Corridor Master Plan design elements:
- Silver's Park Boat Ramp Reconstruction: The existing boat ramp will be rebuilt to improve safety and function. Improvements include widening the boat ramp and angling the boat ramp downstream to increase ramp length and reduce the slope and construction of an eddy to ease loading and unloading. An adjacent pedestrian trail and stone terracing will accommodate increased use in this area.
- South Bank Grading, Stabilization & Vegetation: Restoration and revegetation of the south bank is proposed to achieve stability, habitat, and safety objectives. The proposed work would employ a natural channel design approach that includes re-building the bank, extending the bank out into the river, and establishing a narrow floodplain bench planted with native riparian vegetation.
- Main Channel Debris Removal & Construction of Class II Rapid: The entire project area is riddled with concrete and metal debris that poses safety hazards to wildlife and the public. Following the removal of man-made materials a Class II rapid will be constructed to create a grade control at the crest of the rapid to divert a portion of available river flow into a newly constructed side channel. This rapid will improve recreational experiences while also providing enhanced upstream fish passage and improved aquatic habitat.

- Irrigation Ditch Infrastructure Removal: The concrete irrigation headgate structure will be demolished, and the abandoned ditch behind the headgate adjacent to Downtown Lions Park will be filled in. An estimated 2,600 CY of imported or native fill will be placed in the ditch to restore the surface to match the elevation of the adjacent park and trail. This area, once flattened and revegetated, will expand Downtown Lions Park by formally connecting the park to the adjacent riparian area along the Clark Fork River.
- Side Channel Restoration & Overflows: Much of the fill needed to fill-in the Flynn Lowney Ditch and create a bench for Ron’s River Front trail extension would be generated by digging a new perennial side channel along the north bank of West Broadway Island. The downstream end of the new side channel would tie into the existing slack-water alcove below the California St. Bridge. This channel will be designed to safely accommodate floater passage, serve the wave feature, while also providing aquatic and terrestrial habitat. To protect the side channel during higher flows, overflow channels are included in the side channel design. These overflow channels would be situated at the upstream end of the side channel and would provide locations for controlled overtopping of the side channel banks during high flow to convey water back to the main Clark Fork River channel. The overflow channels would not only reduce potential for flood damage to the side channel but also provide routing and storage of instream debris onto the head of the West Broadway Island.

- North Bank Grading & Revegetation: The steep north bank of the Clark Fork River between Burton and Hawthorne Streets will be regraded and expanded to create gentler overall slopes in the area between private property and the river. The upland bench, outside of the floodplain, will accommodate the extension of Ron’s Riverfront Trail. The riparian bench will accommodate natural surface trails, river access points and riparian forests.
- Ron's River Trail & South Riverfront Trail Improvements: The design proposes an extension of Ron’s River Trail on the North bank from its current terminus at Burton Street to Scott Street. A protected shared-use trail is intended to replace the existing bike lane and sidewalk facilities between Scott St. and the Bitterroot Branch trail. It will provide an improved experience by protecting trail users from vehicles with a raised median wide planted with trees.
- West Broadway Island Habitat Improvement & Protection: West Broadway Island provides important habitat for wildlife migrating through the Missoula Valley. This project will restore and improve this habitat while also establishing an oasis for wildlife within a dense urban landscape. Recreational access to the island will be limited in order to protect riparian habitats. Widening the side channel and removing the bridges from the mainland to the island removes terrestrial access to the island. Establishing “float-in” only access to the island will reduce human impacts protecting spring and early summer migratory bird nesting seasons when there is high flow.

- Recreation Wave Feature: A recreational wave feature is proposed at the downstream end of the side channel. This feature will be designed with river-board surfing as the primary use but will be navigable by other watercrafts. The recreational wave feature will be designed as a fixed feature (no adjustable components) and flows to the wave will be controlled by the design of the side channel and the upstream overflow channels. The feature will be designed to benefit the largest numbers of users during peak river use season. The feature will be designed to be navigable by all river users and emergency services personnel, with no portage necessary.
- River Access Points: On both sides of the river, natural surfaces access trails will connect paved commuter trails to adjacent riparian areas and designated river access points. Establishment of sustainable river access points is essential for protection of streamside vegetation and maintenance of bank stability throughout the project area. These access points will vary in size and may or may not be hardened based on anticipated use.
