The original radio piece ran for 14 months. Following are recordings of the piece re-conceived as a 10 sided record album in April/May 2025.

At the mouth of a river, salt meets sweet water. Tides fluctuate. The river floods and dries with the seasons. The muddy delta shifts position over centuries. At the tideline, life persists. It exists both in and out of the water. A sand spit rises once a day and disappears again. It's a home for clams, oysters, other mollusks, anemones, sand dollars, shore birds and seals. A rock shelf full of tidal pools is filled with tiny fish, crabs, urchins, starfish, bivalves, and seaweed. Fish swim down the river to the sea and return to spawn. Plants and trees are engulfed or left high and dry. As a consequence of (over)use by modern cities and societies, extractive industries dominate a major river and its ecologies, then atrophy and decay, replaced by new modes of global commerce, tourism, and shipping. As ice packs diminish, the seas warm,. Water levels rise and rain patterns change. The spaces between high and low water become more and more exaggerated. The dynamics of change seesaw across the year, creating dangerous patterns in this time of climate crisis.

Water Line is a generative audio piece that imagines the space between the tides and between the salt and the muddy waters. Depending on the height of the tide, listeners are oriented below or above the surface, from deep sea to thousands of meters in the air. Combining field recordings (acoustic and electro-magnetic) with poetic composition, Water Line works with both documentary and imaginary riverspace, the creatures and organisms that live there, the human and the more-than-human. The dynamics range from the roar of engines and turbines to the very subtle sounds of clams, the scuttle and high pitched hisses of crabs, or the scattering of sand fleas. Environmental sounds meet electronic compositions to express the many perceptions of being above or below water. From the undersea kelp forests and high tide zones across the mud flats and swampy areas; from the industrialized river to nearby rocky coves; the artists incorporate field recordings mixed with imaginings and playful interpretations of the river to craft a composition that oscillates across the day, the month and the year.

The piece is centered on the muddy, shifting delta of the river that is called stal̕əw̓ by indigenous hən̓q̓əmin̓əm̓-speaking Musqueam people, or stó:lō by indigenous halq’eméylem speakers, Coast Salish peoples who still inhabit the river valley of what is also known as the Fraser, which winds through the greater metropolitan area of the city of Vancouver. The Fraser's colonial legacy is one connected to extractivist enterprises such as fur trade, logging and pulp mills, mining, fishing and farming; eventually the suburbs of Vancouver encroached across the river delta displacing farms with houses, parking lots, and an international airport. But the river is still its own, a place that the salmon have defined ecologically in many ways, and currently stó:lō still has the largest salmon run of any river in Canada.

Water Line stages and juxtaposes the fictional confluences of stó:lō with sounds from across the Salish Sea (Nanaimo and the Gulf Islands: where the river waters eventually disperse completely into the salt water of the Gulf) and also takes some sounds from the Danube (as homage to the radio stations that supported the project). After 14 months of accumulating new sounds and compositional segments, the piece became Estuary Almanac, a compilation of river-times, documented and imagined, with our ears attuned to the waterline. Though the river banks are built more and more concretely, though the waters hold ghosts of the past that the summer drought brings into view, these are vital rivers whose life spans have and will surely outlast empire.
