Fish go further down than the ice. The ice usually doesn't freeze all the way to the bottom. If the fish are trapped in shallow water or if the lake or stream freezes to the bottom, they will freeze.
An ephemeral stream is a stream that flow with water only following rain storms. The stream quickly disappears when the rain stops.
There are no proper rivers as such, but a number of smaller burns or streams - the most common being the Tower Burn, which is where the town got it's name from - Dunfermline is translated as "the fort by the crooked stream." This is a post glaciation meltwater channel and as such has steep embankments, and today there is only a small, "misfit stream" at the bottom. The stream meanders by over 180 degrees which provided the perfect defensive site for Malcolm Canmore's tower, the remains of which can still be seen today within Pittencrieff Park, or the "Glen" as known by locals.
Not all are. Some stream beds are sandy, and some are rocky.

A stream bed is the bottom (floor) of the stream.

Definition of Streambed: the bottom of the stream below the usual water surface.
Sediment that is carried by a stream along the bottom of its channel.
heavy particles that move along the bottom of the stream.
The particles bouncing along a stream bottom is called saltation. This process involves particles being lifted and transported by the flow of water, before being dropped or settling back to the stream bottom. Saltation is common in streams with moderate flow velocities and bed roughness.
A stream lengthens when downcutting occurs, downcutting is when the bottom of the stream is slowly dug out, this process will dig at the end of the river until it becomes part of the river.
kicking around on the bottom of a stream to collect invertebrates or other small water living animals to check the condition of the stream.
