Platte River Basin

Ovid Reservoir: In November 2006, the District 64 Reservoir Company formed as a
non-profit mutual ditch company, to purchase the Ovid Reservoir site, conditional water
right decree (5,800 AF with refill), and preliminary engineering, from the Groundwater
Appropriators of the South Platte (GASP). Since the purchase, Company representatives
have had several meetings with SPWRAP members (South Platte Water Related
Activities Program) and CWCB staff to begin discussions on possible partnerships for
the development and use of the reservoir. The Company has been working on a SB-179
Grant Application to be submitted in July 2007. In addition, discussions have begun by
CWCB staff on the possible use of $500,000 in existing State funding (SB 01-157),
intended to be used for a feasibility level continuation of the Lower South Platte
reservoir sites reconnaissance study completed in 2001. It is envisioned that the parallel
studies would be coordinated by a joint committee. The Company efforts would focus
on technical issues related to the reservoir construction (revised hydrologic/operations
model, final design documents, construction and O&M costs, permits), and the CWCB
efforts would focus on policy issues related to operation and usage of the reservoir
(potential uses/partnerships, legal considerations, reservoir operating plan/agreement,
facilities ownership & management, financing). Potential uses of the reservoir are
agricultural well augmentation, water administration and Compact management, Platte
River Recovery Implementation Program (3-States) activities, and other fish and wildlife
opportunities.

Chatfield Reservoir Reallocation Study Update: The Chatfield Reservoir
Reallocation team is extremely pleased that the U.S. Army Corps of Engineers approved
$354,000 in the FY 07 budget for continuing efforts on the project. The funding was part
of a Continuing Resolution authority approved by Congress last month. In addition, the
local water users recently provided and extra $200,000 in cash funding for EIS study
purposes. A revised study schedule from the Omaha Corps is pending, and will reflect
all remaining tasks in order to obtain a Record of Decision from the Assistant Secretary
of the Army (ASA) as soon as practicable.

The fundamental scope of the study is to look at the feasibility of converting flood
control storage space in Chatfield Reservoir, owned by the U.S. Corps of Engineers
(Corps), into water supply storage space. The volume for the reallocation analysis has
been set at 20,600 acre-feet based on an Antecedent Flood Study model that was
approved by the Corps.

Cherry Creek Probable Maximum Flood (PMF) Study: The Omaha District of the
U.S. Army Corps of Engineers continues their efforts regarding the Cherry Creek
Probably Maximum Precipitation (PMP) review and revised Probable Maximum Flood
