Project Goals and Objectives
desired future conditions) and the watershed benefit. 1. Support the development of a hydrologically inefficient riverscape that contributes to increased surface flow volume, duration, and extent, and ultimately an increase in salmonid habitat quantity and quality. 2. Accelerate the recovery of self-sustaining hydrologic, geomorphic, and biological processes that increase the extent and diversity of wetland, riparian, floodplain, and channel habitat within the Hay Creek.
Structure Construction Elements
Structure Types and Configuration Primary Structures: The project focuses exclusively on Beaver Dam Analogs (BDAs), not other wood mimic structures like PALS. Quantity: Approximately 160 BDA structures are planned, spread across two treatment reaches: the Wet Fork and the Mainstem Hay Creek. Complexes: BDAs are grouped into 14 structural complexes, each designed to function as a cohesive unit to achieve geomorphic and hydrologic outcomes. Design Specifications Elevation: Crest elevations range from 0.3 to 1.0 meters, designed to encourage overbank flow dispersal and floodplain connectivity. Structure Widths: Crest lengths vary from 2 to 20 meters, depending on location and channel width. Elevation Zones: Design planning used 0.5 m and 1.0 m floodplain elevation surfaces to target short- and medium-term reconnection goals.
