Narrative:

IFR had been cancelled! On 45 degree entry to downwind for runway 32R, a single engine, small aircraft appeared on my right side. No evasive action was taken; however, the 2 aircraft were almost too close. Due to workload, the tower did not give either aircraft traffic, or did not deem it necessary. Due to the traffic load, the 45 degree entry and departure from an airport brings aircraft very close together. This is an example! Tower people cannot always inform every aircraft of every other aircraft in the pattern. I have no solution! Could have inbnds on a 90 degree turn at midfield and departure traffic on the 90 degree/45 degree 2 mi from the aircraft, perhaps.

Title: NMAC ENTERING PATTERN AT CTLED ARPT.

Narrative: IFR HAD BEEN CANCELLED! ON 45 DEG ENTRY TO DOWNWIND FOR RWY 32R, A SINGLE ENG, SMA APPEARED ON MY RIGHT SIDE. NO EVASIVE ACTION WAS TAKEN; HOWEVER, THE 2 ACFT WERE ALMOST TOO CLOSE. DUE TO WORKLOAD, THE TWR DID NOT GIVE EITHER ACFT TFC, OR DID NOT DEEM IT NECESSARY. DUE TO THE TFC LOAD, THE 45 DEG ENTRY AND DEP FROM AN ARPT BRINGS ACFT VERY CLOSE TOGETHER. THIS IS AN EXAMPLE! TWR PEOPLE CANNOT ALWAYS INFORM EVERY ACFT OF EVERY OTHER ACFT IN THE PATTERN. I HAVE NO SOLUTION! COULD HAVE INBNDS ON A 90 DEG TURN AT MIDFIELD AND DEP TFC ON THE 90 DEG/45 DEG 2 MI FROM THE ACFT, PERHAPS.
