Greenleaf Creek and Greenleaf Slough ...
Greenleaf Creek heads on the north and east flanks of Table Mountain, west of Greenleaf Peak and the Red Bluffs, and flows south across Greenleaf Basin. It becomes Greenleaf Slough (also known as Greenleaf Lake) near North Bonneville, at approximately Columbia River Mile (RM) 144. Greenleaf Slough then flows southwest where it merges with and becomes Hamilton Creek. Greenleaf Slough was at one time was the channel separating Hamilton Island and the Washington mainland. Hamilton Creek enters the Columbia River at approximately Columbia River Mile (RM) 143.

Lewis and Clark and Greenleaf Slough ...
Lewis and Clark passed by Hamilton Island on October 31, 1805, calling Hamilton Island "Strawberry Island". They make mention of a dry brook and narrow channel forming the Island, part of the Greenleaf Creek/Greenleaf Slough/Hamilton Creek system.

"... a Brook falls into the narrow Chanel which forms the Strawberry Island, which at this time has no running water, but has every appearance of dischargeing emence torrents ..." [Clark, October 31, 1805]

Greenleaf Creek/Greenleaf Slough/Hamilton Creek ...
Today Greenleaf Creek flows into Greenleaf Slough which then flows southwest where it merges with and becomes Hamilton Creek. All three of those names have appeared on maps as names for this drainage system which once made Hamilton Island an "island".

An 1860 cadastral survey (tax survey) map for T2N R7E show's the "Hamilton Creek" name on today's the Greenleaf Slough and lower Hamilton Creek, forming the north/northwestern channel separating Hamilton Island from the Washington mainland.

Clark, October 31, 1805 ...
A Cloudy rainey disagreeable morning I proceeded down the river to view with more attention [Cascade Locks area] we had to pass on the river below, the two men with me Jo. Fields & Peter Crusat proceeded down to examine the rapids the Great Shute [Cascade Rapids] which commenced at the Island on which we encamped [Ashes Lake, now under the waters of the Bonneville Reservoir] Continud with great rapidity and force thro a narrow chanel much compressd. and interspersed with large rocks for a mile, at a mile lower is a verry Considerable rapid at which place the waves are remarkably high, and proceeded on in a old Indian parth 2 miles by land thro a thick wood & hill Side, to the river where the Indians make a portage, from this place I dispatched Peter Crusat (our principal waterman) back to follow the river and examine the practibility of the Canoes passing, as the rapids appeared to continue down below as far as I could See, I with Jo. Fields proceeded on, at a mile below the end of the portage [Fort Rains] ...     at 2 miles lower & 5 below our Camp I passed a village of 4 large houses abandend by the nativs, with their dores bared up, ...     from a Short distance below the vaults the mountain which is but low on the Stard. Side leave the river, and a leavel Stoney open bottom Suckceeds on the Said Std. Side for a great Distance down, the mountains high and rugid on the Lard Side this open bottom is about 2 miles a Short distance below this village is a bad Stoney rapid and appears to be the last in view I observed at this lower rapid the remains of a large and antient Village which I could plainly trace by the Sinks in which they had formed their houses, as also those in which they had buried their fish- from this rapid to the lower end of the portage [vicinity of Fort Cascades at the lower end of Hamilton Island] the river is Crouded with rocks of various Sizes between which the water passes with great velociety createing in many places large Waves, an Island which is Situated near the Lard. Side [Bradford Island] occupies about half the distance the lower point of which is at this rapid. immediately below this rapid the high water passes through a narrow Chanel through the Stard. Bottom forming an Island of 3 miles <wide> Long & one wide, I walked through this Island [Hamilton Island] which I found to be verry rich land, and had every appearance of haveing been at Some distant period Cultivated. at this time it is Covered with grass intersperced with Strawberry vines. I observed Several places on this Island where the nativs had dug for roots and from its lower point I observed 5 Indians in a Canoe below the upper point of an Island near the middle of the river Covered with tall timber [???],    which indued me to believe that a village was at no great distanc below, I could not See any rapids below <for> in the extent of my view which was for a long distance down the river, which from the last rapids [Middle Cascades] widened and had everry appearance of being effected by the tide,- I deturmind to return to Camp 10 miles distant [on an island by Ashes Lake, across from Cascade Locks, Oregon], a remarkable high detached rock Stands in a bottom on the Stard Side [Beacon Rock] near the lower point of this Island on the Stard. Side about 800 feet high and 400 paces around, we call the Beaten rock.     a Brook [Hamilton Creek] falls into the narrow Chanel [Hamilton Slough, today's Greenleaf Slough] which forms the Strawberry Island [Hamilton Island], which at this time has no running water, but has every appearance of dischargeing emence torrents &c. &c. Jo. Fields Shot a Sand hill Crane. I returned by the Same rout on an Indian parth passing up on the N W. Side of the river to our Camp at the Great Shute [an island near Ashes Lake, across from Cascade Locks, now under the waters of Bonneville Reservoir]. found Several Indians from the village, I Smoked with them; Soon after my return two Canoes loaded with fish & Bear grass for the trade below, came down from the village at the mouth of the Catterack River [Klickitat River], they unloaded and turned their Canoes up Side down on the beech, & camped under a Shelveing rock below our Camp ...

This Great Shute or falls [Upper Cascade Rapids] is about a mile with the water of this great river Compressed within the Space of 150 paces in which there is great numbers of both large and Small rocks, water passing with great velocity forming & boiling in a most horriable manner, with a fall of about 20 feet, below it widens to about 200 paces and current gentle for a Short distance. a Short distance above is three Small rockey Islands, and at the head of those falls, three Small rockey Islands are Situated Crosswise the river, Several rocks above in the river & 4 large rocks in the head of the Shute; those obstructions together with the high Stones which are continually brakeing loose from the mountain on the Stard Side and roleing down into the Shute aded to those which brake loose from those Islands above and lodge in the Shute, must be the Cause of the rivers daming up to Such a distance above, <and Show> where it Shows Such evidant marks of the Common current of the river being much lower than at the present day
