Webster Pond Fish Management

Colorado Parks and Wildlife will treat Webster Pond on April 14, weather permitting, with a very low concentration of rotenone. Rotenone, a natural pesticide derived from the roots of certain members of the bean family from South America, is a common tool that fisheries use to manage fish populations and assist in the management of endangered species. The picnic shelter and trail along Webster Lake will be closed for 30 days after the natural pesticide is applied.

The goal of the project is to establish state-listed native fish species in Webster Pond. Species include the state endangered Northern Redbelly Dace and state threatened Brassy Minnow. In order to properly establish populations of the endangered and threatened species, all sportfish will be removed from Webster Pond.

Parks & Open Space transitioned Webster Pond from a warm water sport fishery to a native fish refuge after the 2013 Flood. Parks & Open Space received a grant from Colorado Parks and Wildlife to create a complex wetland to provide habitat for small native fish. Volunteers contributed hundreds of hours to install over 21,000 plants. Webster Pond is and will remain closed to fishing.

Wetland habitats, nestled within the surrounding Great Plains, support aquatic plant and animal life and serve to lure in large numbers of migrating bird species. With grasses, wildflowers and trees surrounding the wetlands, these areas are biologically diverse both in and out of the water.

From Gravel Mine to Ecosystem

The eastern side of Pella Crossing was opened to the public in 1996 after it was donated to the county by Frontier Materials, Inc. in 1992. The property was an agricultural site before it was mined for gravel from 1975 to 1990.

In 1995 the western property was purchased from Willis and Alberta Marlatt and added to Pella Crossing.

The Name

This spot, called “Laramie Crossing” in 1860s, is where the Overland Trail stagecoach crossed the St. Vrain Creek en route from Denver to Laramie, Wyoming.

Hygiene Elementary 5th graders won a competition to name the donated open space property. They chose the name, Pella Crossing, because the property is the midpoint between 19th century towns Pella and North Pella.
