The egg-mat data describe a sub-set of the egg-mat network operated by the Idaho Department of Fish and Game. The sub-set inlcudes two sites, 1. near an area commonly known as Shorty's Island, and 2. near the Kootenai River confluence with Myrtle Creek at an area commonly known as Myrtle Bend. The egg-mats consist of artificial substrate mats that are deployed and retrieved every 24-48 hours by IDFG personnel. The egg-mat material is designed to trap eggs that come in contact with the mat, allow personnel to quanitify the number of eggs for the deployed period. The egg-mat data is described by date, quantity of eggs retrieved, and the spatial location (geographic and projected coordinates).
