Adventures of fly angler in Poland

 Due to prolonged heat season, we have very low water in all rivers in Poland. The flow in Poprad near the mouth is about 6m3/s. Normally the river flow in September is about 11-16 m3/s.  I came to the river near 7:00. The first stop was in Głebokie. There's fast run under the bridge, where I saw fish 2 years ago. I checked this hole, and barbels are there! There's 3 or 4 fish in very shallow, knee-deep water. I came down and tried to catch it. Unfortunately, probably fish are gone because were spooked by casts. I think I hooked one, but fish briefly flashed and immediately came off the hook. I drove about half kilometer upstream. Parked my car on the dirt road and descended to the river. The area is very shallow, only about 30 cm of water. I concentrated on deeper part of the run, near the opposite bank. I worked through the run, it looks attractive, but not very long.  Then I skipped some very shallow water, and fished the next deep run. Ok, it's not very deep, slightly...
