Goals

  • Improve LPR flow & aquatic health.
  • Improve surface-groundwater connections &

water retention.

  • Alleviate flooding.
  • Improve & expand habitat & recreation
  • pportunities.

Flow Restoration Plan

  • Dozens of wells affect

flow.

  • Closer wells have more

impact.

  • Prioritizing actions by

location / benefits.

  • Groundwater model

quantifying flow increases.

Depletion potential from MODFLOW (WGNHS & USGS)

Potential Flow Restoration Actions

  • Village well operation

changes.

  • Transitioning irrigated

agricultural land to conservation areas.

  • Additional agricultural

irrigation changes.

  • Other actions.

2016

Discharge peaked at 70 cfs. Took 10 days to come back to baseflow.

Reshape channel morphology so the stream interacts with its floodplain more frequently. Based

  • n 1.5 year recurrence interval

that would be 25-30 cfs.
