4.6 Ditch Issues

As detailed in section 3.2.4 above, there are eight jurisdictional ditches in the watershed; the District assumed responsibility for those ditches in 1971.  A detailed review of the eight ditches in was completed in 2003 to obtain a history of ditch constructions, benefiting properties, and current use.

The Board has considered several options for managing these ditches, including continuing as ditch authority, or abandoning or transferring some or all of the conveyances.  A key consideration in determining the most appropriate management strategy is whether the ditch continues to provide a valuable stormwater conveyance function for the watershed or whether it has become primarily of local function.

Four ditches continue to provide valuable subwatershed drainage conveyance.   Both Judicial Ditch #2 (Six Mile Creek) and County Ditch #10 (Painter Creek), convey drainage from an entire subwatershed to Lake Minnetonka.  County Ditch #27 (part of Long Lake Creek) and County Ditch #32 (part of Gleason Creek) are integral to the outlet of the Long Lake and Gleason Lake subwatersheds.

Four ditches have been replaced by storm sewers or some combination of storm sewers and open channels:

  • CD #14 (Bass Lake area into Lake Calhoun)
  • CD #17 (Edina into Lake Calhoun)
  • CD #29 (St. Louis Park into Lake Calhoun)
  • CD #15 (Plymouth into Gleason Lake)

These ditches no longer serve their original function, which in most cases was to drain wetlands and other lands to provide for agriculture.  These ditches or storm sewers provide localized stormwater conveyance, and in many cases maintenance has been provided by the city through which they run.
