Dexter 30-Dam 2 nears completion on Aug. 12, 2020, as the contractor mulches the nearly 2,000-foot-long earthen berm that has a peak height of 21 feet. This berm is the biggest project ever built by CRWD under its Capital Improvement Plan (CIP) to improve water quality and reduce flooding.

CRWD surpasses flood-reduction goal

Largest project yet now functional for stormwater storage in Dobbins

Aug. 21, 2020 — Five years ago this month, local leaders met at the confluence of the Cedar River and Dobbins Creek to announce a $3.2 million grant for improving water quality and reducing floodwaters.

Staff with CRWD and the Jay C. Hormel Nature Center launch a canoe in August 2020 at “The Point” — the confluence of Dobbins Creek and the Cedar River State Water Trail — for a youth canoeing class to take a trip down the Cedar.

Dobbins Creek, prone to flash flooding, covers part of Interstate 90 in June 2008 in northeast Austin near its outlet to East Side Lake. This was one of Austin’s worst-known floods.
East Side Lake’s dam on Dobbins Creek roars during the June 2000 flood — the Austin area’s second worst-known flood. CRWD’s CIP projects will reduce flooding at this site and improve water quality.
