Airspace Structure; Procedure
The event being reported is a near miss at DWH while in the left traffic pattern for Runway 17R. While on the downwind leg just passing midfield; I noticed Aircraft Y slightly above my position coming at me from the 11o clock position. While at pattern altitude; I took positive exchange of flight controls and proceeded to pitch down and to the left aggressively to avoid traffic. When I recovered the aircraft at 900 ft. MSL; I asked the Tower who was above me and they said that the traffic ahead was indicated 1;400 feet MSL no factor. Unfortunately; this was a factor because the aircraft came within 200 feet of my aircraft. Due to the event; my student became stressed and I determined it was time to terminate the flight. To prevent the situation; Tower will have to be made aware of the situation and an earlier scan for traffic could have made the deviation less aggressive.
GA flight instructor reported taking evasive action from traffic ATC failed to report which resulted in NMAC at DWH airport.
