Narrative:

While climbing out visually from dca runway 1 we received a TA and RA for aircraft in opposite direction. We were attempting to follow the river visually and were approximately 2 mi to west of river ground track. The river turns from west to north, and due to our light load and high angle of attack, we didn't pick up our visual reference below until we were beyond them. Supplemental information from acn 458833: I didn't notice the north bend in the river because of the high deck angle of the climb and because it turned away from my side of the aircraft. I was probably 2 mi to the southwest of the river. I think these types of visual departures in high density areas should be discontinued. In the future, I will use the 328 degree radial (which is visual backup) as my primary departure reference. In my opinion, it should be the only departure, as that river gets very narrow and difficult to monitor visually.

Title: A B737-300 CREW, DEPARTING DCA ON A VISUAL FROM RWY 1, LOST SIGHT OF THE RIVER AND DRIFTED APPROX 2 MI SW OF THEIR INTENDED POS, CAUSING A TCASII RA.

Narrative: WHILE CLBING OUT VISUALLY FROM DCA RWY 1 WE RECEIVED A TA AND RA FOR ACFT IN OPPOSITE DIRECTION. WE WERE ATTEMPTING TO FOLLOW THE RIVER VISUALLY AND WERE APPROX 2 MI TO W OF RIVER GND TRACK. THE RIVER TURNS FROM W TO N, AND DUE TO OUR LIGHT LOAD AND HIGH ANGLE OF ATTACK, WE DIDN'T PICK UP OUR VISUAL REF BELOW UNTIL WE WERE BEYOND THEM. SUPPLEMENTAL INFO FROM ACN 458833: I DIDN'T NOTICE THE N BEND IN THE RIVER BECAUSE OF THE HIGH DECK ANGLE OF THE CLB AND BECAUSE IT TURNED AWAY FROM MY SIDE OF THE ACFT. I WAS PROBABLY 2 MI TO THE SW OF THE RIVER. I THINK THESE TYPES OF VISUAL DEPS IN HIGH DENSITY AREAS SHOULD BE DISCONTINUED. IN THE FUTURE, I WILL USE THE 328 DEG RADIAL (WHICH IS VISUAL BACKUP) AS MY PRIMARY DEP REF. IN MY OPINION, IT SHOULD BE THE ONLY DEP, AS THAT RIVER GETS VERY NARROW AND DIFFICULT TO MONITOR VISUALLY.
