Waterscapes can have meaningful benefits for people’s wellbeing and mental health by helping them feel calmer and more connected to nature, especially in times of stress such as the COVID-19 pandemic. The waterscapes along the San Marcos River (Texas, USA) provide economic, social, environmental, and emotional benefits to the surrounding community. To assess the social demand for and emotional experiences in these blue spaces, we used a new framework called Blue Index that collects noncontact data from photo stations. From 10 photo stations across different waterscapes, we collected and analyzed 565 volunteer assessments from May 2021 to March 2022—during the COVID-19 pandemic and following the reopening of riverside parks. Most respondents (57%) indicated they spend more time at the river than they did before the onset of the pandemic. Moreover, 93% of respondents agreed that the waterscape they were visiting represented a refuge from stress and isolation caused by COVID-19. Overall, people valued waterscapes for ecological benefits and relationships with the place, rather than for recreation and tourism. Emotions experienced at all 10 waterscapes were overwhelmingly positive. Statistical tests revealed that higher positive emotions were significantly associated with biophysical perceptions of flow, cleanliness, and naturalness. Our results demonstrate that the benefits of blue spaces derive from an interrelated combination of ecosystem and mental health. The new Blue Index approach presented here promotes participatory land management through noncontact community engagement and knowledge coproduction.
