TICKY CREEK. Ticky Creek rises seven miles northeast of McKinney
and three miles west of Altoga in central Collin County (at
33°14' N, 96°32' W). Intermittent in its upper reaches, the
creek follows a southeasterly course for 16½ miles, passing
within a mile of Princeton and Culleoka. Ticky Creek flowed into
Pilot Grove Creek until the early 1950s, when its course was
diverted to empty into Lavon Reservoir (at 33°06' N, 96°29' W).
The stream lies entirely within the Black Prairiesqv region of
Texas, long considered one of the most productive agricultural
areas in the state. It runs through gently sloping terrain
surfaced by clay at its source and level terrain surfaced by
deep clayey and loamy soils at its mouth. Bois d'arc trees shade
the stream and early in the twentieth century provided timber
for lumber mills at Princeton. Ellen Jeanene Walker,
