Mid Summer Update
Data from the nearest USGS current gauge, located downstream of the study reach,
at Bijou Avenue and Monument Creek.
Student interns completed the high resolution stream profiles at 25 meter spacing, and are working to bring these into GIS and generate a 3D model of the bedrock and gravel stream bed, which will include natural bedrock vanes and constructed vanes. An essay describing their work is just out online! Read more here.

What better way to start the week...
... than with stream-profiling, outdoors on Monument Creek?
Here is a look at the team at work on a stream profile just north of the Uintah Avenue bridge. The water levels are very low. And -- very interesting to the geologists among us -- much of the gravel has been transported away, revealing the underlying bedrock of Pierre Shale.
The crew in the fluoro-vests are, from right: Geodesign interns Darryl Filmore, Will Rundquist, and David Sachs. Jonny Norwine, on left, is a willing geology student who assisted for the day. Seated, on right, is Cyndy Hines, program coordinator for SOTR and Innovation at CC. Cyndy guided the set-up of the stream profile and shared her knowledge of stream hydrology and riparian systems -- to advance the accumulation of foundational knowledge, observational skills, and investigation methods.

Close observation of Monument Creek
The first task is getting to know the stream reach! On Friday afternoon, after two days of discussion, reading of reports and published literature, and initial steps of assembly of the GIS database for the project, David Sachs and Will Rundquist got out on the bank of Monument Creek, for an assessment. State of New Mexico environmental scientist Karen Menetry joined in on the walk and discussion. She was returning to Santa Fe after attending the 2018 Annual Meeting of the Society of Wetland Scientists.

CC interns Will Rundquist and David Sachs met up with environmental scientist Karen Menetrey, to observe the creek and talk over examples of riparian restoration approaches that are successful in similar settings in New Mexico. |

The Good Idea: Monument Creek Phase II, Slowing the Water
This Summer, three Colorado College interns will spend 10 weeks in the field and in the Geospatial lab, measuring stream morphology and flow, gathering data on the riparian ecosystem, and using science and geospatial data to develop a design for environmental restoration of Monument Creek. The project is Phase II of The Good Idea: Monument Creek, sponsored by Innovation at CC and State of the Rockies. Inspired by the Colorado Springs’ founding principles and Colorado College’s strategic plan, the aim of the project is to create a model framework for the kilometer-long stretch of Monument Creek that forms the western border of campus.
Student interns are:

Will Rundquist, senior, Geology Major
Darryl Filmore, junior, Comp.Sci. Major
Collaborators/Mentors are :
Matt Cooney (GIS Technical Director)
Cyndy Hines (Program coordinator, Innovation and SOTR), with expertise in stream ecology & hydrology
Interns will gain strong GIS skills, experience in dialog with community stakeholders, and a strong grounding in the fundamentals of Geodesign. The objective of the summer work is to develop a 3D model design for remediation of the riparian environment along the urban reach of Monument Creek that borders the Colorado College campus. The hope is that the design will provide impetus for joint implementation of measures that will improve streamwater quality, mitigate impacts of floods, aid in education about how riparian environments function/enhance urban environments. The work is carried out in knowledge of the concerted work / ongoing projects of the Fountain Creek Watershed District; Colorado Springs Parks, Recreation, and Cultural Services; Colorado Springs Utilities; and Rocky Mountain Field Institute. Stormwater mitigation and the health of Monument Creek as a part of the Fountain Creek Watershed are an enormous priority for the City of Colorado Springs.
The geospatial database and 3D Geodesign will be used and refined by a larger cadre of students in Block 8, 2019, when CC’s Introduction to Geodesign course is offered for a third time. The landscape design models developed in the course will involve conversation and collaboration with community stakeholders, and culminate with models to be shared with campus and city decision makers who have an ability to aid the objective of reintegration of a clean, healthy watercourse into the CC campus and Monument Creek Park. The project is to be CC’s flagship contribution to Changing our Global Infrastructure, an international geodesign collaboration among academic instutions.
Financial Support is provided by the State of the Rockies Project and Innovation at CC at Colorado College. Thank you!
