through the Los Angeles River watershed from our recent summer intern, Jake Tanda. Jake is a senior at USC and was one of USC Wrigley Institute\u2019s <a href=\"https:\/\/dornsife.usc.edu\/wrigley\/education\/undergraduate-internships\/environmental-communications-internship\/\" target=\"_blank\" rel=\"noopener\">2026 Summer Environmental Communications <\/a>Interns. He was co-mentored by USC Sea Grant\u2019s Dr. Amalia Almada and Sydney Rilum, and worked on promoting healthy watersheds through public education.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Across much of the highly urbanized city of Los Angeles, rainwater flows over streets and into storm drains and waterways, including the LA River, before eventually reaching the Pacific Ocean. Along the way, it can pick up litter, oil, bacteria, and other pollutants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The good news? We can all help protect our shared watershed by reducing waste, properly disposing of pollutants, and keeping our streets and waterways clean. Small actions upstream can make a big difference downstream.\u00a0<\/span><\/p>\n<p><strong>Watch his video &#8220;What is a watershed?&#8221; below to learn more.<\/strong><\/p>\n<p><a href=\"https:\/\/dornsife.usc.edu\/uscseagrant\/2026\/07\/29\/usc-sea-grant-summer-2026-intern-spotlight-jake-tanda\/\" target=\"_blank\" rel=\"noopener\">Read more about Jake&#8217;s summer intern experience<\/a>.<\/p>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--rich-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--rich-text\"\n    \n      >\n\n    \n      \n<div class=\"f--field f--wysiwyg\">\n\n    \n  <div class=\"video-embed\"><iframe loading=\"lazy\" title=\"What is a Watershed?\" width=\"422\" height=\"750\" src=\"https:\/\/www.youtube.com\/embed\/UOXXzDJP-gw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":74,"featured_media":11542,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[110,20,49],"tags":[],"class_list":["post-11539","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-education","category-news","category-student-blog"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What is a Watershed?<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/dornsife.usc.edu\/uscseagrant\/2026\/09\/30\/what-is-a-watershed\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"What is a Watershed?
