Production unit table

Production unit table from the Atlantic salmon Dam Impact Analysis model v67. Division of Penobscot River watershed into sections, or Production Units (PUs). Gives boundaries, habitat units, production potential, and length of each PU.

Usage

Format

A dataframe with 15 observations of 12 variables

PU Production unit number (Neiland et al. 2015) Boundaries Boundaries used to delimit PU HU Habitat units HU_scen Habitat units in default scenario Proportion_of_HUS_in_scenario Proportion of habitat units within PU (of entire watershed) Adjusted_proportion_of_HUs_in_scenario Adjusted cumulative proportion of habitat units within PU (of entire watershed) Smolt_production_potential Number of smolts that can be produced in each PU based on HUs Longest_segment_length_km Maximum segment length of PU (km) Partial_segment_length_1 First partial segment length, if applicable Partial_segment_length_2 Second partial segment length, if applicable Hatchery_segment_length Length of hatchery stocking segment Dam Name of dam at downstream end of PU
