A sampling of the BDAs (Beaver Dam Analogs) we have built along San Antonio Creek, including a post-less BDA. Our BDAs have mostly utilized posts as anchors to lodge other woody materials against, in order to create robust structures. Surface bedrock along some stretches of stream posed a creative challenge and opportunity to construct some without posts.

In 2020, we expanded upon previous restoration efforts along San Antonio Creek between the Valles Caldera boundary and San Antonio hot springs. We installed 9 BDAs and 17 log baffles within the stream channel, and protected a 10 acre swath of riparian meadow from elk and cattle browse using fencing with passthroughs for recreational access. We decommissioned .25 miles of old road, installed erosion control structures in several ephemeral, eroding gullies and reset two eroded alluvial fans.
