The Dodder lay well beyond the original city of Dublin but began to have an important impact in the 13th century when water from its course was diverted to boost the small Poddle River, which in turn supplied fresh water to parts of Dublin. In the late 1400s, the river itself was probably regarded as part of the defensive ditch of
the Pale which surrounded Dublin, according to Archbishop Alen's Register, which in 1487-8 described the line of the Pale thus: And in the third yere of King Henrie the seventhe, by acte of Parliament in Drogheda holden the friday after the Epiphanie, the bundes if the iiij obedient shires within the Macre distinct from the Marches were limite with in the countie of Dublin from Miryonge (Merrion) (inclusive) to the water of Dodor (
Dodder), by the neve diche (
ditch) to Tassagarde,
Rathcowle,
Kilhele,
Rathmor and
Ballymor, and so from thens to the
countie of Kildare etc. Over centuries, the Dodder and its tributaries drove many mills, crucial to Dublin's industrial base, but all are now disused. In many cases, all traces have been erased but there are some remaining, such as millraces. The
de Meones family, who gave their name to the nearby suburb of
Rathmines, owned a mill in that area as early as the mid-fourteenth century. In the sixteenth century much of the surrounding lands belonged to the Talbot family, ancestors of the Talbots of Mount Talbot. In the seventeenth and eighteenth centuries the
Domvile family, who owned much of
Templeogue, effectively controlled access to much of the river, which passed through their estates. At that time the Dodder was the main source of Dublin's
drinking water, and whether fairly or unfairly, the Domviles were accused of using their control of the Dublin water supply to further their own selfish ends, by threatening to divert its course if their wishes were not met. In fact, the legal right to control the course of the river was vested in the Mayor and Corporation of Dublin; this was confirmed by a court ruling as early as 1527.
Flooding The river floods some surrounding areas from time to time, as it is too short and shallow to hold the volume of water which pours into it from its tributaries during heavy rain. The River Dodder "has a history of flooding and is known as a "flashy" river with a quick response to rainstorms." A flood on the Dodder in March 1628 claimed the life of Arthur Ussher, Deputy Clerk to the
Privy Council of Ireland, who was "carried away by the current, nobody being able to succour him, although many persons.... his nearest friends, were by on both sides." The two greatest Dodder floods before 1986 occurred on 25 August 1905, and on 3 and 4 August 1931.
Hurricane Charley (often spelt "Charlie" in Ireland) passed south of the country on 25 August 1986. In 24 hours, 200mm (almost 8 inches) of rain poured down on
Kippure Mountain while 100mm fell on Dublin causing heavy river flooding, including the Dodder in many places, and hardship and loss were experienced. ==Flora and fauna==
