These stepping stone sets are installed at intervals along the channel - not only to help peope cross over, but also to 'break up' the flow of water and presumably keep it from stagnating.

Paint Branch Stream by Janna Chapman

This image is of Paint Branch Stream in College Park, Maryland towards Metzerott Road. Construction on The Enclave (background) and new Tempo apartments (downstream) off of Route 1 are major contributors to the poor water quality of the stream. Sediment runoff from construction sites like these in addition to riparian tree loss along the 14-mile stream has resulted in turbid water that blocks sunlight and makes it difficult for underwater organisms to survive. Sediment also stresses stream capacity and velocity. This in turn affects land organisms that rely on fish and macroinvertebrates. Restoration efforts have included building fish passages for easier migration and bank supports/improving root density to prevent erosion. Better sediment trapping at construction sites themselves also helps prevent water degradation.

This photo is connected to Sustainable Development Goal 14: Life Under Water. Even though Paint Branch itself is not a large body of water like this goal focuses on, it flows into the Anacostia River and that flows into the Chesapeake Bay. Suspended sediment can travel far and is a prominent problem in the Bay area that threatens various aquatic species from Oysters (C. virginica) to Striped Bass (M. saxatilis). Preventing erosion at lower stream orders helps lower accumulation at higher orders, and makes for a healthier marine environment.

This image looks nothing like what I saw. My camera simply knows that lights and colors are present, even when my eye sees nothing but gray and brown. My job is only to present possibilities to my gear, not to "see" finished images.
