About this file
This document is a technical engineering drawing file from the Oregon Department of Fish and Wildlife, specifically detailing rearing and picking trough specifications for the Klamath Hatchery. The file provides comprehensive design specifications for 20 rearing troughs and 4 egg picking troughs, with detailed technical requirements for construction materials, dimensions, and structural components. Key specifications include a 25-mil glossy smooth inner isophthalic gelcoat layer, aluminum screen construction, PVC drain couplings, and precise dimensional requirements for trough design, including maximum deflection limits and screen slot configurations.
The technical drawings specify precise manufacturing details such as 14-gauge aluminum sheet materials, 18" round perforations, aluminum angle framing, and specific mounting instructions for screens and baffles. Each trough type has unique construction requirements, with rearing troughs featuring deflection control members and picking troughs including specialized baffle plates and egg basket supports. The drawings include exact measurements, material specifications, and total quantity requirements, indicating a standardized approach to hatchery infrastructure design with attention to precise engineering tolerances and fish management infrastructure needs.
